About the Grenada Meteorological Service

The Grenada Meteorological Service (GMS) observes, forecasts and warns on the weather affecting Grenada, Carriacou and Petite Martinique. It is the country's authoritative source for weather warnings, and the official provider of meteorological services to aviation and marine users.

The service runs the national observing network, issues the daily public forecast and the warnings that follow from it, provides aviation products for Maurice Bishop International Airport, supports the National Disaster Management Agency during high-impact events, and holds the national climate record.

Trusted — official, consistent, and traceable to forecaster authority.

Timely — issued on schedule, updated when conditions change, and archived for accountability.

Actionable — built around the decisions people need to make, not only what the weather will be.

Interoperable — machine-readable, standards-compliant, and shareable with regional and international partners.

Resilient — available during high-impact events, when it is needed most.
