Hm, Medellin might be a little "hot" in other ways to be a comfortable place to live, d'you think?
We usually have about 7 months of the year where we can sleep with the windows open. I adapt better to a few months of sunny and muggy than freezing and gloomy. In actual fact I think our hottest day this summer only got to 93, cooler than a lot of places! Even on the hottest day, the beach is delightful, and we played golf at least once a week in the evenings last summer. As long as there's a breeze it's fine. We'll often get a thunder shower in the late afternoon, too. That really cools things off.
I'm from the Pac. Northwest originally and it's very nice to visit up there in August, I'll admit.
