The drought status on this page is not yet published from the GMS forecast system. The figures on this page are illustrative and must not be used for any weather, marine or safety decision.
| Area | Status | Trend |

| Northern Grenada | Mild dryness | Steady |
| Interior highlands | Normal | Steady |
| Carriacou | Moderate dryness | Worsening |
| Petite Martinique | Moderate dryness | Worsening |
Both islands are lower and drier than mainland Grenada and lack the interior highlands that generate orographic rainfall. They also depend more heavily on rainwater harvesting, so a dry spell reaches households faster.
A drought that is an inconvenience on mainland Grenada can be a water supply emergency on Petite Martinique.
Drought status combines rainfall deficits over several timescales — one month, three months and six months — because short and long dry spells have different consequences. A single dry month is not a drought; a persistent deficit across months is.
Assessment is done with water resources authorities, since the impact depends on storage and demand as much as on rainfall.
