Temperatures range from 70 in the winter to the 80s in the summer. Rainy seasons vary by island, but usually late spring and fall are the wettest months. Hurricane season stretches from June through November. As summer progresses, the hurricane probability increases; the most likely month for a storm is September. The Dutch Leeward Islands--Aruba, Bonaire and Curacao--and Trinidad and Tobago are south of the hurricane zone.
