October Drought Forecast Map


Although the Caribbean Sea and the North Atlantic Ocean will remain warmer than normal (Linked to increased rainfall), other environmental conditions such as the Saharan Dry Air and warm sea surface temperature anomaly over the eastern Pacific Ocean will continue to influence rainfall patterns across Jamaica. Therefore, as we approach the upcoming rainfall period of August to October, there is a moderate chance that the island could experience a below-normal to near-normal season. Temperatures, on the other hand, are likely to remain warmer than normal throughout the period, based on the latest findings from the seasonal climate forecast model.

Jamaicans should brace for more heat stress and related impacts, especially during the month of August. The Meteorological Service will continue to monitor the findings from the models in the upcoming months so as to advise our stakeholders, especially our farmers.
