Weather Update.....What Clouds ?

Yesterday Mazatlan experienced a rarity....fog that covered the beach and lingered for much of the day. While it does make a very occasional appearance, typically any fog in Maz gets burned off rather early in the morning. Or it may pop up during the day for 30 minutes or less, then retreat outside the islands or just disappear altogether.

Since this is a misunderstood subject let's spend a minute talking about exactly what fog is, and how it's fits into the climate.

Everybody understands it's wet when it's raining. However most people don't realize there can be a lot of moisture in the air on a "dry" day without a cloud in the sky. The fact is there is always moisture in the air, even in the desert summer. The only question is....what form it takes.

In the Mazatlan summer we'll talk about how humid it is. That is a result of water in suspension, that soon becomes water on our brow. Since the water molecules are so small and evenly disbursed into the air...you can't see them.

Later that afternoon a cloud cover moves in, and a rain storm will form. Now you have that very same water coming out of suspension and turning into rain drops big enough for you to see as they fall to the ground.

In the Mazatlan winter we may have a day without a cloud in the sky, then suddenly fog seems to roll in out of nowhere. In truth the fog doesn't "roll" anywhere. What does come in are conditions which cause the moisture that was suspended there in the air, to change form.

Not into bigger drops that fall as rain, but tiny, tiny drops that catch the breeze and float while turning the air into a soupy mix too thick to see through.

Just remember that most of the time clouds form when moisture comes out of suspension well up in the sky. If these moisture drops become big enough or heavy enough, they eventually fall as rain. However with fog you are literally seeing a cloud form right at ground level.

Moving back to our weather picture, as predicted today on Wednesday the royal blue sky returned and it left the high white clouds behind. Better yet the sun joined with calm seas to create seas in a gorgeous shade of aquamarine. The temperature got into the 70's quickly, and then kept moving right on up over 74 degrees. It was a classic beach day.

Look for more of the same with clear skies and beautiful conditions for most of the days going into next week. One or two days may have some cloud cover, but there is no rain or fog in the mix. Temperatures will continue to be right in the perfect range, with Friday and Saturday the coolest days.

The only negative, and it's a small one all things considering, is it may be a little breezy tomorrow and Friday. Not too strong, but enough to cool things slightly on Friday and Saturday as mentioned. By Sunday things should be right back to the calm days.

In fact Sunday looks perfect for that afternoon excursion to El Quelite or Copala....so have a great time !

Mazatlán, Sin...

Quick update:

The breezy conditions may be arriving later than expected, mostly occuring later this afternoon and evening with a noticable drop off for tomorrow. Consequently today may end up being quite warm like yesterday, and it wouldn't be until Saturday any cool down would occur.

By cool down we're still talking about 70 degrees (21.2 C.) for a high, and with very mild winds so it would still feel nice and warm. Sunday still looks to be the end date for any temporary effect on the terrific weather Mazatlan is currently having.

Looking forward from there into next week we could see even warmer days ahead. Stay tuned.

We figured it was a sign it was time for us to go home with the gloom on Tuesday after a perfect Monday for our last full day! The fog did not extend very far inland as the airport was clear but when we flew out you could see it on the coast by town and motel zone.

The number of days Mazatlan has any fog at all is rather low. To see a day where fog actually envelopes the beach and lingers throughout the day? Wow, that probably averages less then one day per year so for a random tourist to have that experience would be a real long shot. ridgerunner you are yours joined a very, very exclusive club.

The wind took it's time arriving, but once in town it didn't waste any showing some bluster. By 3 P.M. it was very breezy, and just before sunset there a couple gusts close to 30 mph (48 kph)

Don't be discouraged for while tomorrow will still have some wind, the strong stuff will die off overnight. Moreover the direction is from the due north, more or less straight down the beach. So if you're not on the water the wind drops off considerably. For example the velocity at the airport today was limited to an unremarkable 12 mph (19 kph).

The sky will still be very clear so a warm sun will help temper the wind chill factor, and by Saturday the calm will return. Now for those who are packing up for next week in Maz ?? Stay tuned for the next update, because I think you're going to like what you hear.

Just finished packing this morning and driving to Spokane this afternoon for our flight out tomorrow, so this is very welcome news indeed. My wife is in need of a great vacation and weather is an inevitable part of that equation.

Thanks for the weather updates AquaMaz, you are good with a turn of phrase and definitely the" Bard of the Barometer ! "

As maxexp mentioned (in the beach walking thread) the Mazatlan sky was visited bright and early today by a band of cumulus clouds They're the ones that look like big cotton balls. Originally these clouds were tracking northerly across the neighboring state of Sonora. However the strong winds yesterday afternoon pushed them south into Sinaloa.

Today is a mixed bag of news. The cloud cover will prevent the temperature from reaching its expected high of 70 (21.2 C.), however the winds are dying down as expected. They're about half the velocity of yesterday, and the ocean was noticeably calmer at noon then it was at dawn.

The clouds will gradually drift back to the north as the wind subsides; the only question is will it clear today or tomorrow. The good news is they'll leave with a nice parting gift, and if you're currently in Mazatlan don't miss the sunset. Cumulus clouds often provide the most colorful and breath taking sunsets you could imagine.

Saturday will continue with our clearing sky, while both the sea and the air will calm to normal conditions. The air temperature will also climb a little. Here's the best news of all. Sunday through Tuesday is still on track to have lots of sun and warming temperatures.

Yes, yesterday's gusts caused a few flying beach umbrellas. Bring a jacket or sweater if you are going to be out in the evenings, as it's better to have it and not need it, than the other way around. It cools quickly when the sun vanishes.
