Oh we have humidity
In the summer it is generally from 85% to 98% and the temps are in the 90's F. What seems dry to us is in the winter when the humidity drops to the mid 50% to 60% area, I need chapstick then
Spring is our most uncomfortable season, April and May are very hot (often over 100°f) and very humid but with no rain. When the rains finally start in June they drop both the temperature and the humidity and the "feel" becomes much better. The lesson here is if you are coming to the Yucatan, don't do it in April and May
