Drought Forecast Map


The forecast for the upcoming three months, March to May 2018, indicates a near-normal to above-normal rainfall pattern over most areas of the island.

Over the period, the forecast indicates that rainfall and temperatures are likely to be higher than normal. Hence, there are very little concerns for drought at this time as current and forecast conditions point to higher than average rainfall during the season.

The Meteorological Service will continue to monitor the findings from the models in the upcoming months, so as to advise our stakeholders: especially farmers, accordingly.
