May Drought Forecast Map


The forecast for the upcoming three-month period of March to May indicates that rainfall is likely to be near-normal to above-normal, while temperatures are expected to be above-normal but seasonally comfortable.

During the forecast period, the island will transition from the dry season to the early wet season. This near-normal to above-normal rainfall outlook should, therefore, be interpreted within context; that is since rainfall amounts have been below-normal in recent months, some sections of the island could experience further deficits in water availability. Effective management of this resource, such as conservation, rainwater harvesting and the prudent use of irrigation are some strategies which could prove advantageous throughout this period.

The Meteorological Service will continue to monitor the situation and provide updates to our stakeholders.
