The climate in Honduras is hot and tropical in the coastal lowlands with annual temperatures averaging 26°– 29°C; it becomes more temperate in the highlands where annual temperatures average 16°– 24°C. Average annual precipitation is lowest in the central mountainous interior (800 –2000 mm) and highest in the Caribbean coast (+2,000 mm) where rainfall is year-round.
The Pacific coast and interior highlands have a dry season (summer) from November – April and a wet season (winter) from May – October that experiences a short break (1–4 weeks) in July/August (the canícula). For the most part, El Niño events decrease rainfall and increase temperatures, while La Niña events decrease temperatures and increase rainfall.
