It depends on what time of year you will be there. The temperature doesn't vary much but the humidity is a good deal lower in January/February (I've never been there in Dec. or March). We used to go to the Caribbean in June & the difference in the comfort level was enormous! Go in the "dry" months if possible! I'm not very heat-tolerent, but I find that visiting in February is not too bad & if there's a good breeze, which is almost all the time, it's quite comfortable. Of course, when you go into the interior, where the wind is cut off, it's a lot more uncomfortable!
