I love heat too, and even humidity. I'm originally from Calif which is dry but moved here 5 years ago and it is very humid here. Mexico is a huge country and many parts of it are dry but mostly the coastal areas are humid (outside of the Bajas and northwestern desert coastline). There are many people, including Mexicans, that will tell you that Merida is unbearably hot and humid but I've found it to be less humid, and often less hot, than Houston or New Orleans. We are about 20 miles inland from the Gulf and get afternoon breezes without the steady driving winds. I adjusted pretty easily, don't even use AC, but keep the fans running in the summer. It helps that I live in a very old house with really high stone walls and ceilings. It stays cool inside even when it is a scorcher outside. My pond temps get up into the 90's in the summer and rarely drop below 80ºf anytime. I mostly have Mollies and Guppies in the ponds and the heat doesn't seem to bother them. I also have some Angel fish to keep the population of smaller fish under control, they too have adjusted to the high water temps and the high PH. I'd love to have some Discus in the ponds but they are said not to tolerate high PH very well so I've resisted.
