Climate of Guanacaste
Guanacaste experiences little rain and consistent heat from November to April, and a wet season from late May to November. Its hot, dry climate makes tropical dry forests to be the province’s natural vegetation type. The one exception is the highland portion of the province which consists of the upper Pacific-facing slopes of the volcanoes in the Guanacaste Cordillera and the northern half of the Tilarán Cordillera. The cool, moist conditions along these ridges support luxuriant cloud forests.
The main reason for the diversity in Costa Rica’s weather is the various elevations at which different parts of the country are located. For example Guanacaste has a dry arid climate as it sits on the lowlands.
The perfect time to visit Guancaste is year around. No matter if you visit during the dry season or during the wet season, both provide spectacular advantages.
The dry season affords the serious sun lover with plenty of tanning time, while the wet season brings the trees into bloom with explosions of colors and fragances. The rolling hills become carpeted in brilliant green.
