In the winter, temperatures rarely fall below 60°F, and usually reach 77°F by mid-afternoon. During the summer, temperatures fluctuate between 85–90°F in the daytime and 75°F or less in the evening. Although humidity can reach about 80% (relative humidity for September is 82%), prevailing easterly winds lessen personal discomfort. Temperatures vary from a low of 76.7°F in January to a high of 89.1°F in August. Humidity causes mildew on leather and textile products, but homes equipped with central air‑conditioning or dehumidifiers neutralize the harmful effects.
Rainfall often occurs in the form of fairly intense showers, frequently accompanied by strong, gusty winds. These storms are usually short and are followed by clear skies. Weather conditions can change rapidly. Statistically, a hurricane can be expected to occur in some part of the Bahamas every nine years.
