April Drought Forecast Map


For the forecast period of February to April 2018, the models are indicating, a higher probability of above-normal rainfall over most areas of the island.

Over the upcoming three-month season, the forecast seems to be highly confident that the period will be wetter than normal. There are very little concerns for drought at this time as current and forecast conditions point to higher than average rainfall during the season. Temperatures for the same period are likely to remain near normal to above-normal.

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.
