October Drought Forecast Map


The forecast for the upcoming three-month period of August to October 2020 from the CPT indicates that rainfall amounts are likely to be above-normal, with warmer than normal temperatures.

Projections for the upcoming three months are that the island could experience a noticeable increase in rainfall when compared to recent months. This forecast is consistent with Jamaica’s annual rainfall cycle where September usually marks the beginning of the primary wet season, with the peak occurring in October.

With Meteorological Drought conditions currently affecting most parishes across the island, the expected rainfall should bring some relief from these conditions, as well as provide recharging for water storage facilities. The occurrence of bush fires should decrease as the number of days with rainfall increases during this season. Warmer than normal temperatures could result in heat stress impacts especially on days with little to no rainfall.

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