Aruba Weather in September: Rain, Temperatures

Aruba weather in September somehow escapes the bad weather that usually hits the rest of the Caribbean.

The average rainfall for the island in September is less than two inches. The average temperature is 91 degrees Fahrenheit or 33 Celsius.

September historically is the worst month of the annual Caribbean hurricane season. The region averages four tropical storms during the month. Three develop into hurricanes and two grow into major hurricanes.

Aruba Rain in September

When other destinations average six to 13 inches of rain during the month, arid Aruba averages less than two inches, according to the Aruba Meteorological Service. The nearby Curacao also averages about two inches. These averages are based on a 30-year history and may vary somewhat from year to year.

Aruba usually has about one inch of rain per month from January through August and then three inches from October through December.

Other Caribbean destinations experience bad weather in October and then a drop in total rainfall in November, which is the final month of the hurricane season.

The fact that Aruba historically has light rain in September is not a guarantee that it will get light rain every September. The paths of storms and hurricanes are unpredictable. Even if rain doesn't increase, bad weather in the region can increase cloud cover over Aruba.

Over a 30-year history, the island has averaged four days with rain in September compared to 11 in November and December.

Temperatures in September

The average high temperature of 91 Fahrenheit or 33 Celsius in September is the highest of the year.

August, October and November are only slightly lower at 90 Fahrenheit or 32 Celsius. They compare to the low point for daytime temperatures of 86 Fahrenheit in January.

Water temperatures around Aruba average a balmy 83 Fahrenheit during the month. Swimming is normally comfortable all day long.

Comfortable temperatures and low risk of rain make Aruba the best island to visit in the Caribbean for weather during September. But bad weather elsewhere makes Aruba more risky during September than earlier months of the year.
