Aruba is a constantly windy island that is located on the southern fringes of the Caribbean. Although a hurricane is rare, there is still the possibility of storms in the vicinity during hurricane season. Storms may actually cut down on the wind at times, but there are times when the effects of a Caribbean hurricane will cause beach sand to blow around.
With an average rainfall just over 20 inches, anytime of the year is perfect for a visit to Aruba. Rainy season runs from late October into the beginning of January, but mainly in the form of short showers. December will see an average rainfall of 3.3 inches or rain versus May which receives a half inch of rain. Either way no worries here about being stuck in a hotel room staring at raindrops all day. Day time temperatures run a summer average of 90° F. and winter average of 87° F. Night time lows rarely fall below 80° F. in the summer or 76° F. during the winter. The only need for a sweater arises from the air conditioning when the restaurants or casinos get too chilly.
