Climate of Bonaire

Climate of Bonaire

The island of Bonaire belongs to the Leeward Islands in the Caribbean and has been officially a Dutch municipality since Sunday October 10, 2010. This gives Bonaire the honor of having the warmest climate in the Netherlands.

Bonaire has a tropical savanna climate (type Aw according to the Köppen-Geiger classification). Temperatures are fairly constant throughout the year, with maximum temperatures around 30-32 degrees Celsius being reached fairly quickly during the day. Once the evening has fallen, the thermometers slowly lower until a lower limit of 23 to 25 degrees is reached. Under the influence of the Caribbean Sea and the east trade, there is only little variation in temperatures. In the winter months, these two elements ensure that the land is warmed up somewhat, in the summer the wind over the at that time relatively slightly cooler sea has a cooling effect. Don’t take that last word too literally, because it never gets really cool on Bonaire.

Ideal holiday destination

If we choose to measure ourselves, Bonaire is climatically one of the very best holiday destinations in the world. It is always warm, without getting too hot. The predictable and almost always present easterly wind ensures that it is also bearable on Bonaire during the hottest days. The sun shows itself a lot and rain occurs, but not in too large quantities. You can hardly have better beach weather.

It is not for nothing that Dutch travel organizations such as TUI are successful in offering Bonaire holidays. They have been offering a very varied range of accommodations with flight and transfer for many years.


Many sites describe Bonaire’s climate as tropical-arid, meaning that it is a dry climate with tropical temperatures. We will not dispute that the temperatures are continuously at tropical values. To call the climate dry is something that is debatable, because on average there is almost five hundred millimeters per year at the Flamingo Airport weather station. This is really an average with quite a few drier years in between, with about three hundred to four hundred millimeters. However, it is also very possible that as much as a thousand millimeters of rain will fall within one year. Especially in a year in which a hurricane comes eerily close and/or one or more severe tropical depressions pass over, the total amount of rain can increase considerably.

Most rain falls in the last quarter of the year. The months of October, November and December account for about half of the total amount of precipitation per year. The months of February, March, April, May and June are the driest. On average, there is less than 20 mm of rain per month during that period. However, there are also months in which no precipitation is observed at all and nature craves some rainwater.


Bonaire is a sunny island, with an average number of hours of sunshine per day from eight to nine hours. On an annual basis, the total number of hours of sunshine averages around three thousand, which can be regarded as extremely sunny. The blue sky above Bonaire is often mixed with beautiful cloudy skies, which can stand out sharply above the azure coast and the deep blue sky above. About a third of the time, the sky is mostly or completely covered by clouds. The chance of this is about the same throughout the year. The chance of a whole day of cloudy weather or even longer is especially present in the period from September to December.

Dive destination

Around Bonaire you will find a beautiful underwater world, which attracts many divers and snorkelers to Bonaire every year. Seawater with an average annual temperature of 26.8 degrees Celsius and almost never cooler than about 25 degrees Celsius provides ideal living conditions for tropical fish in this part of the Kingdom of the Netherlands. If you want to go diving in the autumn, you should take into account that the sea can be rougher than usual due to tropical depressions.


As far as rain is concerned, it is not that bad on Bonaire, but there is a fairly high relative humidity on the island. The annual average humidity is 76 percent. Distributed over the year there is relatively little variation in this, the difference between the driest months and the most clammy months is only a few percent humidity. The fact that all that moisture in the air does not often grow into showers is mainly due to the limited surface area of ​​the island and above all the almost lack of height differences. Zones with clouds that mainly consist of rain clouds will therefore pass Bonaire fairly easily and only provide rain on the mainland. Venezuela is especially the victim of this.


In the Caribbean, there is a risk of hurricanes and tropical storms from early June to early December. Bonaire is located in a place within the Caribbean where the chance of a real hurricane is much smaller than elsewhere. Some sites report that tropical storms and hurricanes do not occur on Bonaire. That this is not based on truths is shown by tropical storm Omar, which in October 2008 caused a lot of misery on Bonaire and yet also caused the necessary damage. Fortunately, these kinds of circumstances on Bonaire are an exception. Most of the nuisance from hurricanes and tropical storms consists of rainfall and rougher seas as a result of depressions to the north of Bonaire.

Winter sun

The pleasant temperatures in winter in combination with a lot of sun make Bonaire a very popular winter sun destination. Especially the months of February to April are great to go diving, snorkeling or swimming on this beautiful island. People with skin that is not yet used to the sun must be extra careful during these months with regard to limiting the risk of sunburn and all the associated consequences. The sun power is also at a very high level in winter on Bonaire.
