Geography & Environment
Dominica is a rugged volcanic island in the Eastern Caribbean, with steep ridges, deep river valleys and narrow coastal lowlands. Morne Diablotins is the island's highest peak, and moist trade winds interacting with the mountains produce a humid tropical marine climate.

Understand the landscape
What Dominica's geographic profile is telling you
Dominica's steep volcanic relief strongly controls its local weather and drainage. Trade-wind moisture rises across the central mountains, helping generate heavy rainfall and a dense network of short, fast-flowing rivers and valleys.
