The average weather in St. Maarten in August has a high temperature of 89 degrees Fahrenheit or 32 Celsius. Rainfall is about four inches.

This eastern Caribbean island is hugely popular with cruise visitors because of the fabulous port at Philipsburg on the Dutch side of the island. Philipsburg has both a vibrant shopping and dining district and a large beach—Great Bay Beach—within walking distance of the cruise docks.

The island is most popular from December through April, according to statistics from the Caribbean Tourism Organization. It is less popular in the summer and fall because of rain.

Total Rain and Rain Days in August

August is not nearly the most popular time to visit St. Maarten because the risk of rain is higher than normal as a result of the Caribbean hurricane season.

Still, the historical average of four inches, reported by the Meteorological Service of Netherland Antilles and Aruba, is not as bad as September with five inches and November with six inches.

Another way to judge the risk of bad weather is the average number of days with rain each month. St. Maarten has 14 average days with rain during August compared to nine in February and March, which have the lowest number of the year.

St. Maarten Temperatures in August

The island usually has more rain in August, but it also has more warmth. The average high air temperature is 89 degrees Fahrenheit or about 32 Celsius. The average low temperature is 79 Fahrenheit or 26 Celsius, the meteorological service says.

Water temperatures usually stay about midway between the highs and lows of the day. For St. Maarten, the average water temperature is about 83 Fahrenheit or 28 Celsius. Unlike winters, the water temperature is comfortable during most if not the entire day.

August is not the best month of the year to visit St. Maarten. For a combination of warm temperatures and low risk of rain, the better months are March and April. For summer travelers, June and July are better than August.
