For those who don’t like humidity 5,000’ of elevation reduces heat and humidity. Due to elevation and mountains nearly all climates are in Ecuador. I’ve even read that around the equator ppl can just about order their climate such as “I want upper 50s at night and low 80s daytime with humidity below 60%” and it can be found.
Oh, and many of these places are on the dollar or have favorable exchange rates. Some even have Super Walmarts in town. Health care is cheaper too.
5000 feet up the side of a volcano. 70s by day high 50s by night year round and a large expat community you just described San Marcos Costa. It’s on my list of Central American places to chill at. Panama City is also on the list but the climate is brutal. Patagonia and the Argentine Pamapas as well. Starlink opens the entire planet for $200 a month to digital nomads. Truly paradigm shift, Iridium which I own a sat phone from us basic voice and sms. Starlink is broadband anywhere on Earth if you can make profit digitally remote it’s the way to.go.
The wife’s best friend lives near Lake Chapala, Mexico, loves it. Apparently there upwards of 30,000 Americans in the area.
