Climate and monthly weather forecast
Monteverde, Costa Rica

Nestled in the mountainous northern part of Costa Rica, the climate of Monteverde is shaped by the predominating Köppen climate category - Aw, otherwise known as tropical wet and dry or savanna. This classification points toward the dual character of Monteverde's climate: months of lingering moisture interspersed with distinct dry periods.

Throughout the course of a calendar year, the average high temperatures in Monteverde range narrowly between 26°C (78.8°F) to 29°C (84.2°F), with the mercury hovering more towards the upper limit during the months of February to April. Concurrently, the average low temperatures across the year vary from 18°C (64.4°F) to 19°C (66.2°F), suggesting a meager distinction between night and day temperatures. This phenomenon creates a uniform thermal profile that sees both diurnal and seasonal fluctuations within a slim margin.

Aside from temperature, Monteverde experiences favourable sunshine with an average daylight duration varying from a comfortable 11.5 hours to a generous 12.7 hours per day. These numeric values widely correspond to the UV index that remains high at 10 to 12 throughout the seasons. While the sun shines copiously, around 6 to 8 hours of it constitute direct sunshine.

Despite seemingly stable temperature and sunlight patterns, the rainfall scenario presents stark contrasts. A distinct dry period from February to April is marked by rainfall under 67mm (2.64") which gives way to bountiful precipitation from May to November.
