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. According to the USAID Climate Risk Profile, key historical climate trends include:
- Average annual temperature has increased by 0.6°C per decade since 1960, with greatest warming in the dry season.
- The number of warm days and nights have increased.
- Heavy rainfall events have increased by 1.2% per decade since 1960.
- Although trends in annual rainfall are inconsistent, rainfall patterns reduced in northwest and southeast since 1960.
- Since 1960, El Niño/La Niña cycles have increased in frequency and intensity.
