Here at Lake Arenal the tempuratures range year round from a freezing 70 degrees to a sweltering 85 degrees... ; )
In other words, perfect every day and night. A lot like Hawaii, too, as we will have short, heavy tropical rains which may last for an hour or two, and then the sun comes smiling through.
In this mild climate they don't build homes with heaters or A/C units, so the average electric bill is usually $10 to $20 per month!
What a change from the $400 to $500 we were paying in Fresno!
