Jamaica’s rainfall pattern consists of two peak periods with higher values of rainfall and corresponding periods of lower rainfall amounts. The primary peak occurs in October and the secondary in May. The lowest amounts are at a minimum during the period of January and February. This is based on long term reports and deviations from this pattern do occur year to year. The hottest temperatures generally occur between the months of May and October.
The general monthly temperatures range between 21 and 33 degrees Celsius, however, a fluctuation between temperatures throughout the day must be taken into consideration. Mornings tend to be the coolest time of day, with little or no rainfall. While late morning through late afternoon experiences a rise in temperature, with occasional showers with the peak hitting in the mid-afternoon. Early evening into night generally brings cooler temperatures with little or no rainfall.
