Bonaire’s monthly weather has average daytime temperatures ranging from the low 80s Fahrenheit in the winter to the high 80s in the summer. Rainfall average one to three inches a month.

Some months are better than others. Bonaire’s climate and monthly weather are quite similar to nearby Aruba and Curacao. This southern Caribbean island is dry and warm most of the year.

Temperatures vary only a few degrees each month. It has much less rainfall than the rest of the Caribbean and only a slight increase in rain during the late fall and early winter months.

This Dutch island near the coast of Venezuela receives a small number of tourists each year from cruise and hotel visits. It is known mainly for snorkeling and diving.

When is Bonaire’s Rainy Season?

The Bonaire rainy season is during October, December and especially November, when it averages 4 inches, according to the Meteorological Department (of) Curacao. These are the peak months of the Caribbean hurricane season. It has only slightly more rain than nearby Aruba.

It also compares well to the 10 inches or more for places in the middle of the Caribbean hurricane season such as Cozumel.

Like Aruba and Curacao, Bonaire lies just south of the Caribbean hurricane belt, which is most active in the fall months. As a result, it rarely feels the effects of hurricanes that go through the 1 million square miles of the Caribbean Sea. But it is not immune to bad weather.

The chart shows average monthly temperatures in Fahrenheit and average monthly rainfall in inches.

Thanks in part to its southern Caribbean location, the average high temperature annually is 87 degrees Fahrenheit or 31 degrees Celsius. The average low temperature, which takes place mostly at night, is 78 degrees Fahrenheit or 26 degrees Celsius.

Temperatures reach a high point of 89 degrees Fahrenheit or 32 degrees Celsius in August, September and October, according to the Meteorological Department (of) Curacao. It is one of the warmest islands in the Caribbean.

The high temperatures are still warm during the winter when they reach an average of 85 degrees Fahrenheit.

Water temperatures vary by only a few degrees year-round. It makes swimming a more comfortable experience during the winter months than what visitors experience in Cancun, the Bahamas and other northern destinations.
