Wind – December 8, 2024

¡Buenos dias! The thickening high clouds that crept up from the south yesterday put a lid on our developing thermal, and while the wind gauge at the campground showed sustained winds peaked at 15-17 mph, it only lasted for about 1.5 hours (see nerd note below). Infrared satellite loops early this morning showed persistent thick, mid-level clouds over our area, but all of the latest model forecasts show these should begin to move off to the east around noon today and give us a window this afternoon for our local thermal to al least partially kick in. An Oceansat satellite pass last evening measured 10 knot NNW background flow over the southern Sea of Cortez but model forecasts show the background flow will weaken a bit this afternoon and approach the lower threshold for activating our local wind machine. Bottom line is it’ll be really close today. The latest model forecasts for Monday show sufficient north background flow and with mostly sunny skies expected, we should see a rideable afternoon. The norte is still on track to hit Tuesday, with typical first day norte gusty conditions expected. Low-end norte conditions should last though Wednesday, with better quality winds expected. The latest model forecasts for Thursday through Saturday are a hot mess, with models showing significant differences in the overall surface pressure pattern over our region. At this point it looks like we may see rideable wind each day, but confidence is very low.

  • Today…Cloudy this morning, then becoming mostly sunny this afternoon. North wind 14-16 mph.
  • Monday…Mostly sunny. North wind 16-18 mph.
  • Tuesday…Partly sunny. North wind 22-26 mph and gusty.
  • Wednesday…Sunny. North wind 20-24 mph.
  • Thursday…Sunny. North wind 16-18 mph.
  • Friday…Sunny. North wind 16-18 mph.
  • Saturday…Mostly sunny. North wind 18-22 mph.

Nerd Note: Yesterday was a great example of how sensitive our local wind machine is to cloud cover. The wind gauge at the campground measured winds at 15-17 mph from just before noon to a little after 1 pm (see graph). Satellite images from just before noon showed a narrow clear slot in the high cloud shield right over us. That’s about the time that the winds peaked, but by around 1 pm the clouds had quickly moved back in and our winds dropped rapidly.

Wind – December 7, 2024

¡Buenos dias! Although an Oceansat pass last evening measured similar background NNW flow to what we’ve enjoyed the last several days, infrared satellite loops this morning showed a band of thickening high clouds was creeping northward into our area, and this will likely at least partially dampen our local thermal today. A couple of the model forecasts do show some thin spots may form this afternoon in the cloud shield, so I’ll be optimistic that we can get just enough filtered sunshine to give us a rideable day. Most of the high clouds should move off to the east on Sunday, and model forecasts show just enough north background flow will continue to bring us a windy afternoon. Similar conditions are expected on Monday, but we may see a few more high clouds returning. Strong surface high pressure is forecast to build into the southwestern U.S. on Tuesday and send a surge of north wind down the Sea of Cortez, with norte conditions expected here. The norte should subside a bit on Wednesday, but we will still likely see another windy afternoon. Long-range model forecasts disagree on the amount of north background flow that will remain on Thursday and Friday, but a couple of them do show enough to continue our streak of windy days.

  • Today…Partly sunny. North wind 16-18 mph.
  • Sunday…Sunny. North wind 16-20 mph.
  • Monday…Mostly sunny. North wind 16-18 mph.
  • Tuesday…Mostly sunny. North wind 22-26 mph and gusty.
  • Wednesday…Mostly sunny. North wind 20-24 mph.
  • Thursday…Mostly sunny. North wind 16-18 mph.
  • Friday…Sunny. North wind 16-18 mph.

Wind – December 6, 2024

¡Buenos dias! A pair of ASCAT satellites measured 10-15 knot winds over the southern Sea of Cortez last evening, and again, all of the most recent forecast model runs show similar background north flow will continue today. Infrared satellite loops do show a few thin, high clouds streaming in from the west, but we should see ample sunshine to trigger our local thermal. The surface high centered far to our north over Utah will gradually weaken tomorrow, but enough background north flow will continue, and with only some thin, high clouds expected from time to time, we should add to this latest windy streak (see nerd note below). It now appears that a weak ridge of high pressure will form over the central Baja Peninsula on Sunday and last through Monday…with just enough north flow to give us rideable days. Strong high pressure is then forecast to build into the southwestern U.S. on Tuesday, with norte conditions developing here. The norte may continue through next Wednesday, but long-range model forecasts show winds decreasing substantially on Thursday.

  • Today…Mostly sunny. North wind 18-22 mph.
  • Saturday…Mostly sunny. North wind 16-20 mph.
  • Sunday…Sunny. North wind 16-20 mph.
  • Monday…Mostly sunny. North wind 16-18 mph.
  • Tuesday…Mostly sunny. North wind 22-26 mph and gusty.
  • Wednesday…Sunny. North wind 22-26 mph.
  • Thursday…Mostly sunny. North wind 16-20 mph.

Nerd Note: So far it seems like this has been one of the best windy seasons in recent memory, so I did a quick check of the number of windy days so far. Using the metric of sustained winds of 15 mph or more for at least 1 hour, there were 22 days in November, or 73%! The trend has continued into December, with 100% of the days so far meeting those criteria. If the current extended range model forecasts hold, we could see kiteable winds through the 16th of December. Our current windy streak started on November 28th, so that would make 19 straight days!!

Cerralvo Island Adventures

In October, my dad and I enjoy/survive our annual Isla Cerralvo Camping Trip. October is one of the best times to find snakes in our area and — amazingly — this was our third year in a row pulling off a Cerralvo trip during this crazy time of year. 

When we arrived on the beach of the island, spirits were high. We had everything we needed for a great trip. We started setting up camp but then the wind made its Appearance. We brought out our tarps and discovered that they were very old and would rip if you looked at them wrong. 

After a frustrating few hours, we gave up on our tarp fragments and either huddled under our umbrella or stayed in the ocean for the majority of the day. Once the sun started to set, I began exploring the dunes. I found my favorite little junk pile and flipped every bit of metal in hopes of finding the endemic Savage’s Sand Snake (Sonora savagei). 

These little snakes are not easy to find because they spend most of their time below the surface of the sand. However, underneath objects they will come up to enjoy the heat coming through the object, while still being protected from scary day creatures plus have access to their favorite foods such as crickets and scorpions. 

I flipped the entire metal pile and found nothing. I was disappointed until I noticed one more piece of metal underneath the exact center of an extremely extensive and luscious thorn bush. 

I was barefoot as I was not expecting to go thorn diving, but I have experience with thorny areas and bare feet, and I couldn’t miss this opportunity. I shuffled my way on all fours into the mass of vegetation. After a few minutes relocating branches and getting an impressive majority of leaves stuck in my hair, I arrived at the target. I took a deep breath, and flipped it.

Underneath that metal there was a lot of life, including a sand snake! It burrowed underneath the sand, and I started raking with my fingers in the sand with hopes of finding it burrowed underneath. To my surprise, my raking did turn up a sand snake, but this time it was a young one. I was able to grab it, and I kept going to find the other one. Then I noticed a scorpion in the corner. It was a little bit too close, and it was staring at me with the air of an irritated assassin. I recoiled a bit, but then the sand moved, and I extracted the second sand snake. The scorpion left its post and I put the metal down. I was so excited that I almost forgot about the prison of thorns. I made my escape, and I had just found two Savage’s Sand Snakes.

Pantropical spotted dolphins 

We had many dolphins swimming in our bay recently! Common and bottlenose dolphins are the most common species here in La Ventana, but each now and then we find other species, one of them being the pantropical spotted dolphins (Stenella attenuata). Smaller than other dolphins, they are fast, playful, and highly acrobatic, irradiating a contagious joy. They love bow-riding and are very interactive, sometimes making eye contact from the water as they swim. 

As their name indicates, they inhabit tropical and sub-tropical waters worldwide being probably the most abundant dolphins in the world. They are grey, with a darker dorsal cape, and have a dark and light spotting which is highly variable between individuals. They have no spots when they are born and develop them as they age, their spotting pattern is unique and can be used for photo identification. As they glide in the blue water, their spots look like glitter, shining bright. 

Pantropical spotted dolphins often associate with yellowfin tuna, hunting together, last day we saw them, we could see the tuna hunting in front of the group. They feed on different offshore pelagic fish like lanternfish and flying fish, but they also eat squid and crustaceans and they usually hunt at night. Their association with tuna, caused a sharp reduction in their population during the 1980s, as tuna fishing boats were frequently capturing them together. Many dolphins were killed during this time, and more than 4 million were pantropical spotted. This sparked the famous and successful dolphin-safe tuna campaign, which led to changes in legislation, reducing mortality greatly. Thanks to these efforts, pantropical spotted dolphins now are listed as Least Concern by the IUCN. Change is possible, always be an informed consumer and choose what you eat to minimize impacts on our planet!

Side-blotched Lizards

At first glance, side-blotched lizards appear to be essentially classic lizards: small, fast and brownish with a bit of blue. Yet these lizards are remarkable in their own ways. My goal this week is to teach you how to identify one — and how to impress your friends by teaching them how to identify one — along with a few fun facts.

There is some debate whether we have here in LV/ES the western or common subspecies, but it doesn’t really matter unless you plan on doing DNA samples. Side-blotched lizards are usually no more than 5 cm (2 in) long, excluding the tail, which is sometimes longer than the lizard itself. Side-blotched lizards are actually somewhat hard to find around here; they aren’t rare, they just seem to live in little pockets of desert, completely avoiding other areas. Just an hour north, however, they become ever present.

If you see a side-blotched lizard, usually you see a little movement, then you stare into the spot where you saw it for a while, then you decide it was nothing and start turning around before the lizard moves again, and stares at you with the superior air of royalty, knowing he’s untouchable. Then it runs deep into the nethers of whatever bush it was sitting next to, and there is no hope of seeing it again. 

Side-blotched lizards have pointy snouts and usually come in shades of grayish brown with lots of little spots of blue, yellow and other colors on their sides and backs. Their tails are most often just gray or slightly blue, and their eyes are black and extraordinarily snobbish, although I may be biased based on the fact that I have never managed to catch one. Somehow they always have an escape route. Anyway, they are gray, have blue spots, except for sometimes they don’t because sometimes they are striped, and sometimes they look just like every other type of lizard. For the sake of this column, we are going to stick with the most common color scheme: gray or brown with spots.

Male side-blotched lizards sometimes sport amazing reds, yellows, blues and oranges, and/or have black spots just behind their front legs. These should be the easiest traits to spot. They seem to love coming out right around the time the sun goes behind the mountains, and I have even seen them at night occasionally. There are some interesting studies about the males of different colors having different mating strategies, somewhat like a rock/paper/scissors match, but I am running out of space, so maybe more on this next time. 

What impresses me most about side-blotched lizards is how adaptable they are. They inhabit some tiny islets with just a few bushes on them; they thrive on the sidewalks of La Paz; and essentially the same lizard can be found all the way up to Washington state! They are definitely impressive lizards, even if they are a bit stuck up.

Pilot Whales

Recently we had some beautiful cetaceans visiting our bay: short-finned pilot whales (Globicephala macrorhynchus). They were sighted for a few days in our area. Even though they are not super rare to see here, they are not common, so it was fascinating seeing them, but also the fact that we saw maybe hundreds of them, as long as we could see, fins broke the water’s surface.

Pilot whales are odontocetes, toothed whales, and are part of the marine dolphin family. They can look like other dolphins but are much bigger, reaching 12 to 20ft in length (4 to 7m), and have a very characteristic rounded and bulbous melon. This round head gives them their scientific name, from the Latin globus, which means globe, and is an outstanding characteristic that will help you differentiate them. They are black to dark gray/brown with a white anchor-shaped patch in their chest, that looks like a bow tie and have a wide and hooked dorsal fin.

They live in warm waters worldwide and are known for being highly playful and social. They live in matrilineal groups, consisting of a matriarch with her immediate family. They remain in their family group for life. The males leave their groups to mate with members from other families during temporary aggregations of different groups. Females go through menopause, meaning they have important roles once they stop reproducing, like helping care for the calves and as keepers and transmitters of their ecological wisdom.

Short-finned pilot whales feed mainly on squid; they can dive more than 3200ft (1000m) hunting for it. Before we found the pod, we saw pieces of squid floating on the surface, so looks like they had a fest that day!

Pilot whales are often found in aggregations with other species, we saw them hanging out with bottlenose dolphins. They have a complex repertoire of sounds that they use to locate food and for communication. They have strong social bonds, which could explain the frequency of mass strandings in this species.

We enjoyed the presence of several families that formed a huge pod that surrounded us, sometimes coming close to our boat. Mothers traveling with their babies next to them and big males, all together swimming in our waters, a great start to a new season!

Kissing Bugs

Today I am not writing about reptiles because I believe this subject is important. Here in La Ventana/El Sargento, we are at around 24 degrees latitude, and this means we are very close to the tropics. We are lucky, for the most part, that there aren’t too many dangerous creatures in our area. Most of us are familiar with Black Widows and rattlesnakes, but there is one local dangerous insect that many people do not know about, and that is the Kissing Bug.

Kissing bugs are large, blood-sucking insects inhabiting much of Central America. Our local species, Dipetalogaster maxima, is not all that common, but I have seen individuals just outside of town. They are relatively easy to identify, as they are quite large.

The reason these insects are dangerous is because they transmit a disease called Chagas. The disease is not transmitted when they bite, but rather when they poop on you, which is basically whenever they bite. Chagas disease can be deadly. Learn more about it at the CDC.

Luckily, Kissing Bugs are nocturnal and like to inhabit rocky arroyos, so they are not often encountered. They only really feed at night so, as long as you are sleeping in a tent, you should have nothing to fear. 

The moral of this story is: Never sleep outside without a tent in Southern Baja.

Swimming with Oarfish

For those of you that missed my previous post, Swimming with Oarfish, a video I made earlier this summer, here it is again. This is my second Oarfish rescue encounter taking place this past May of 2024, on the very same beach where the video Oarfish Rescue was filmed just two years before, almost to the day.

Oarfish are truly amazing deep water filter feeders living in waters between 600-3000 feet deep. Why they get beached no one knows for sure, but in this video, Swimming with Oarfish, after observing the behavior of this fish, I take a shot at a hypothesis.

If you see a beached Oarfish, if it’s stilll alive and kicking, you can help it into the water. But do so carefully, because, although they can grow up to 36 feet, they are delicate creatures with sensitive skin and an easily breakable dorsal fin that they can’t swim without. Stay tuned, my next video post, How to Rescue an Oarfish, will provide tips on how to save an Oarfish without doing harm.

If you spot a beached Oarfish, note the time and location, please contact me. I’m launching the Oarfish Beaching Awareness Project to gather data on beached Oarfish around La Ventana Bay- reported by local residents. That way we can track the location, time and frequency of these beachings and learn a little more about this fish. 

If someone has a color printer and wouldn’t mind hanging a few posters about this project around town, please let me know. Thank you. Contact William at desertplayer@hotmail.com
