The Windward Islands, also known as the Islands of Barlovento, are the southern, generally larger islands of the Lesser Antilles. They lie at the eastern end of the Caribbean Sea, between latitudes 12° and 16° N and longitudes 60° and 62° W and include, from north to south, the English-speaking island of Dominica; the French département of Martinique; the English-speaking islands of Saint Lucia, Saint Vincent, and Grenada; and, between Saint Vincent and Grenada, the chain of small islands known as the Grenadines.

The geology of the Windwards is volcanic, with craters, hot springs, and sulfuric vents found in the mountainous central ribs of the islands.

The climate of the Windwards is marine, and the extreme tropical heat is greatly tempered by the steady trade winds and daily sea breezes. A dry season alternates with a wet season, with the eastern sides of the islands receiving more rainfall because of the prevailing northeasterly trade winds. Hurricanes are a threat from June to October.
