19 degrees north of the Equator, the Cayman Islands experience a tropical and rather pleasing climate year-round. The warmest season is the rainy season of May-October, when temperatures climb and rain contributes to rather uncomfortable levels of humidity. Thundershowers are often heavy and brief during these months, and cause occasional flooding. Hurricanes sometimes lash the islands. Rainy season temperatures top-out at about 85 degrees F (29 C) and during the rest of the year average 10 degrees F cooler (24 C).
