Agriculture weather

Rainfall and dry-spell outlooks for growers.

Not yet available from GMS

Agricultural guidance on this page will appear here once GMS publishes it.

Who this is for

Grenada's growers work nutmeg, cocoa, banana, and a wide range of vegetable and root crops, much of it on steep ground where rainfall runs off quickly. Livestock and small-scale poultry operations face their own heat and water constraints.

The weather questions that matter here are rarely about a single day. They are about whether a dry spell is breaking, whether a planting window will hold, and whether the ground is saturated enough that more rain becomes a landslide risk.

Rainfall by season

Season	Months	Character
Dry season	January – May	Lower rainfall, higher irrigation demand, elevated fire risk late in the period
Wet season	June – December	Higher totals, tropical waves and cyclone risk, saturated ground
Transition	May – June	Onset timing varies year to year and is the key planting decision

Guidance the service provides

Monthly rainfall summaries by station, seasonal rainfall outlooks, and drought status for the tri-island state. During dry spells these are the products that inform irrigation scheduling and water rationing decisions.

Heavy rainfall warnings carry particular weight for agriculture on slopes, where the risk is soil loss and landslip rather than standing water.
