The climate of Bonaire
The island of Bonaire is part of the Leeward Islands in the Caribbean. Since Sunday 10 October 2010 Bonaire has officially been a Dutch municipality. This means Bonaire has the warmest climate of the Netherlands. According to the Köppen-Geiger climate classification Bonaire has a tropical savannah climate (Type Aw). Temperatures are reasonably constant all year round. Maximum temperatures are 30-32 degrees Celsius which are reached quite early in the day. As soon as the evening falls temperatures drop to 23-25 degrees Celsius. Because of the influence of the Caribbean Sea and a north east trade wind there is little variation in temperatures. During the winter these two elements warm the land while during the summer they offer a cooling effect. However, do not take this too literally; it never really gets cold on Bonaire. Temperatures below 20 degrees Celsius are hardly ever recorded. Wintry conditions such as snow and subzero temperatures are simply impossible here.


Many internet sites describe Bonaire’s climate as tropical-arid. This means it has a dry climate with tropical temperatures. Temperatures are indeed continuously around tropical values. However, the climate isn’t really dry. The Flamingo Airport weather station records about 500 millimeters of rain per year. This is an average though. Some years get less precipitation, about 300-400 millimeters. It may also happen that the total amount of precipitation in one year exceeds 1,000 millimeters. Especially when a hurricane comes close or there is one or more tropical depressions the amount of rain will increase. Most of the rain falls during the last quarter of the year. October, November and December get about half of the total annual amount of rain. February, March, April, May and June are the driest months. These months get less than 50 millimeters of rain per month. However, during some months there is no rainfall at all which makes nature crave for water.

Bonaire is a sunny island that gets about 8-9 hours of sunshine per day. On an annual basis this means about 3,000 hours of sunshine which is very sunny. The blue skies are often mixed with clouds; a beautiful sight over the azure blue sea. About one third of the time skies are cloudy. Chances of cloudy skies all day long are highest in the period from September till December.

Diving destination
Bonaire has a beautiful underwater world which attracts many divers and snorkelers every year. The temperature of the sea is 26.8 degrees Celsius on average; it hardly ever drops below 25 degrees Celsius. This makes for ideal conditions for tropical fish. If you would like to go diving in autumn you should bear in mind that the sea is rougher because of tropical depressions.

Humidity figures
Bonaire doesn’t get a lot of rain. However, humidity figures are reasonably high with an average of 76%. The difference between the dry months and the most humid months is only a few percent. The reason the moist air doesn’t grow into showers is because the island is small and the lack of differences in altitude. Most of the rainy clouds pass Bonaire to cause rain on the mainland. This often is Venezuela.

From the start of June till December there are chances of hurricanes and tropical storms in the Caribbean. Bonaire is situated in an area with a small chance of hurricanes. Some internet sites say that tropical storms and hurricanes don’t occur here. However, in October 2008 tropical storm Omar caused a lot of damage on Bonaire. Fortunately, Bonaire usually doesn’t have the risk of getting hit by this phenomenon. Depressions usually are north of Bonaire and the only inconvenience is more rain and rough seas.

Winter sun
The pleasant temperatures in combination with a lot of sunshine make Bonaire an ideal winter sun destination. Especially from February till April it is very nice to go diving, snorkeling or swimming here. Bear in mind that the UV-index is still very high during winter.
