December Drought Forecast Map


For the period of October to December, rainfall amounts are likely to be near-normal to above-normal based on the latest forecast from our computer model. Also, ocean temperatures are likely to remain near average over the next three months. This will result in little or no ocean signals and, therefore, lower forecast confidence. The forecast continues to indicate that temperatures are more likely to remain warmer than normal for the upcoming three-month period, October to December, based on the latest findings from the seasonal climate forecast model.

Although the forecast indicates near-normal to above-normal rainfall amounts, Jamaicans should continue to utilize various water conservation methods to cushion the effects from dry spells experienced in recent months. Citizens are also, advised to remain alert since the chance of flash flood events during the wet season, is likely. The Meteorological Service will continue to monitor the findings from the models in the upcoming months and advise our stakeholders accordingly, especially our farmers.
