You're so right! On a cruise where we stopped at the San Blas Islands off Panama in late April it was very hot.......imagine! It was a wonderful stop and so few ships stop there I feel very fortunate to have been there. It was a wonderful experience.
Getting back on the ship and on the elevator, everyone was complaining about the heat - I remarked (just before getting off), "Uh, it's April, it's near the Equator, it's hot. Didn't you know we were coming here? You might want to investigate an Alaska cruise". Thankfully I got out alive.
I also am annoyed that so many people say "I don't know why we stopped here - there's nothing here". Ah, no Target, no Nordstroms, no Taco Bell, no Applebee's - I get it. Some people should not travel.
