Tides around Grenada

Grenada has a small tidal range — typically well under a metre between high and low water. Tide alone rarely causes flooding here.

The risk comes from combination: a high spring tide arriving alongside storm surge and heavy rainfall can push water into low-lying parts of St. George's that any one of those alone would not reach.
