Climate in Bonaire

The climate of Bonaire is tropical semi-arid, hot all year round, since the temperature fluctuates between 30 °C and 33 °C (86 °F and 91 °F) during the day. The hottest and more sultry period runs from May to October. However, the north-east trade winds constantly blow, tempering the heat.
From February to August, the south-east trade winds blow, which come from South America and bring dry weather, while from October to January, is the period of the north-east trade winds, which are a little less intense and can sometimes bring rain.

Bonaire is a flat island, with a certain shortage of fresh water because of the lack of rivers.

Bonaire is an island located in the Caribbean Sea at 12 degrees north latitude, about a hundred kilometers (60 miles) north of the coast of Venezuela, and it's an official part of the Netherlands. Together with Curaçao, Aruba and some islands of Venezuela, it is catalogued among the Leeward Antilles, namely, those islands that have an arid climate in comparison with the rest of the Caribbean, as evidenced by the vegetation consisting mainly of shrubs and cacti. The three islands that once belonged to the Netherlands Antilles (Aruba, Curaçao and Bonaire) are sometimes called ABC Islands.

Temperature and rain

Kralendijk

In the capital, Kralendijk, the average temperature fluctuates between around 27.5 °C (81.5 °F) in January and February, and 30 °C (86 °F) in August and September.
Rainfall only amounts to 465 millimeters (18.3 inches) per year. There is a relatively rainy period between October and December when, however, rainfall remains below 100 mm (4 in) per month. The rains, brought by the northeast trade winds, continue with some frequency also in January and sometimes in mid-February.
The sunshine amount is good in all seasons, so much so that there are over 3,000 hours of sunshine per year.

Sea temperature

---

The sea in Bonaire is warm enough to swim in throughout the year: the water temperature ranges from a minimum of 26.5 °C (79.5 °F) in February and March to a maximum of 29 °C (84 °F) in September and October.

Hurricanes

---

From June to November, but especially from August to October, there is the danger of tropical storms and hurricanes: at these latitudes, they are relatively rare compared with the rest of the Caribbean, but it is not impossible that they reach the Leeward Antilles and Bonaire, as happened with Hurricane Irene in September 1971, Joan in October 1988, Bret (tropical storm) in August 1993, Ivan in September 2004, and Felix in September 2007.

When to go

---

Having a hot climate with little rain, the island of Bonaire can be visited all year round. However, the best time is from mid-February to late May, being the driest of the year and outside of the hurricane season. During this period, temperatures gradually rise.
Summer, from June to September, is the hottest period, although the trade winds make the heat more bearable. The weather is almost always good even in this season, but there may be some showers, usually of short duration.
In the October-December period, there is moderate rainfall, although generally not excessive; sometimes, this relatively rainy period continues until the month of January or the first half of February.
The period from August to December can be avoided, because from August to October there is the risk (albeit low) of hurricanes, while from September to December it is the rainiest period of the year.

What to pack

---

All year round: bring light, tropical clothes, made of cotton or linen, and possibly a light raincoat for thunderstorms, especially from October to January. Those who are sensitive to cold can bring a light sweatshirt for the evening.
When going to the reef, you can bring snorkeling equipment, including water shoes or rubber-soled shoes.
