Last updated:
Sweet spot: January, February, June. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
💡 Good to know
- February–April and September–October often bring drier spells to the Caribbean coast. This itinerary keeps Cahuita to a land-based coastal walk; snorkelling requires a separately arranged boat and suitable sea conditions.
- Green turtles nest around Tortuguero from July to October. This itinerary includes the daytime visitor centre and a short Cuatro Esquinas land-trail visit; nesting walks require a separately arranged licensed guide and are not included.
