Twelve-month statistical averages for temperature, wind, humidity, and daylight duration
The climate profile for Île Plate presents detailed atmospheric measurements based on a representative coordinate in the Rivière du Rempart District. Covering the 1991 to 2020 climatology period, these monthly averages provide consistent data for mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and total daylight hours. These figures represent long-term regional patterns rather than daily forecasts or current weather conditions.
