July Drought Forecast Map

JULY 2019 SPI DROUGHT FORECAST FOR JAMAICA

As we start to transition into what is considered to be the secondary rainfall season for Jamaica (May-June) and the start of summer in the northern hemisphere, we are likely to receive about average amounts of rainfall as well as warmer than average temperatures. Although, the island could experience an increase in rainfall over current conditions during May and June. However, in July the island could receive below normal rainfall with warmer than normal temperatures, which could result in some areas experiencing drought and heat stress.

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.
