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.
