Zihuatanejo has a southwest facing bay so that helps. We have utterly open ocean. The neat part about this area is Mex 14-D. In an car the tolls to Patzcuaro and Morelia are not expensive. 0 to 7,000 ft altitude in two and a half hours.
The region is unsurpassed for agriculture. I bring fruits, vegetables, nuts and other items back, prep them and into the freezer they go. Avocados. Gigantic black avocados that belong on the cover of a gourmand's magazine .50 EACH. That 40 pounds of berries I mentioned earlier cost thirty dollars. Carnero (lamb) a dollar eights cents a pound. Having a chest freezer for this is a must. And while some pooh-pooh the idea, I have the stuff and they don't plus I go to the store one-fourth as often.
When we arrive in Patzcuaro around noon, the girls immediately pass-out. The adults yawn. I doubt if anyone sleeps worth a damb when sunrise means 80+ degrees and 90% humidity. Everyone in the pueblo gets testy during hot spells.
Mexicans endure it stoically. But when new transplants claim "Mexicans are used to it" I smirk.
Savvy gringos make a small windowless room, punch a hole in a wall opposite the afternoon sun, for a small window A/C stick a couple of recliners in there with laptops and hole-up from 1:00 - 6:00 PM
A high velocity fan upon exiting the shower is a treat.
My special hours of the day are 0500 to 0700
