Nicaragua in the southern half is HOT. Ometepe does get a lake breeze from the east, and it has a lot of shade trees.
The NW of CR is similar to Nica, arid lowlands and farms, the coast is always hot.
The mountains are cooler, so Arenal area, Monteverde Cloudforest, Orosi and the Central Valley are always pleasant, even the capital is nice its at 3000ft above sea level, San Jose is always a nice breeze, night is perfect..
Chirrpo, San Isidro, Rivas, San Vito are rather pleasant....
