Bonaire’s weather stands out in two key ways from many of its Caribbean neighbours: It is dry (les than 22 inches of rain annually, and it is a little bit hotter – it can get as hot as 35-37ºC on occasion in the summer months. Winds are remarkably consistent – 25 k.p.h. much of the time, making it ideal (on the Windward side of the island) for windsurfing and kite surfing. The Leeward side of the island is, by contrast, much calmer and perfect for diving & snorkelling. The consistent calm on the Leeward side is responsible for the profusion in coral growth in shallow waters, allowing many dive sites to be reached by simply wading into the sea and dropping down.
The resulting vegetation in Bonaire is suited to low rainfall and windy conditions – plenty of cacti and small bushes, though more arguably fecund in the north in Slaagbai National Park, and you’ll notice the remarkable (bent over) Divi trees, reminding you of just how consistently the winds blow around here.
The hottest months are April-September and the wetter ones are between October-January. One should remember that Bonaire is, for the most part, very dry and these wetter months are far drier than those of their Caribbean neighbours.
