Climate and average weather in French Guiana

French Guiana has tropical monsoon climate with a lot of precipitation throughout the year. There is a clear drier period and a long rainy season.The temperature in French Guiana is virtually all year around the tropical value of thirty degrees Celsius (86° Fahrenheit). In the dry season it is usually slightly warmer as the sun shines much more. At night the mercury drops well after midnight to a minimum value of approximately 23-24 degrees Celsius (71-76°F). In the highlands of the tumuk humak mountains in the south of French Guiana it can be slightly cooler. The large amounts of rainfall and high temperatures provide a very high humidity so it may feel very clammy in French Guiana. This tropical dampness is experienced throughout the year.
