Climate:
The climate in Costa Rica is hot all year round. Temperature variations are low because the country is located near the Equator, so the main difference between the seasons is found in the rains. Most of the country is so rainy that it is covered with rainforests. On the Pacific coast and the plateau, the dry season is from December to April and the rainy season from May to November, during which rainfall is abundant. In contrast, in the eastern plains and coasts the climate is equatorial, with abundant rainfall throughout the year. The Pacific coast is slightly warmer than the Caribbean coast, especially in winter, when the north-east trade winds descend from the mountains and become hot and dry: the average daytime temperatures are around 30°C in October and November and November and can reach 35°C in March and April, before the rainy season. There is a well-defined dry season from November to April, at least in the central-northern part, while going south, the dry season becomes progressively shorter (it rains fairly often even in December and April), and in the southernmost part the climate is even equatorial, like on the coast of the Caribbean Sea. The north-central part (province of Guanacaste, canton of Puntarenas) is particularly hot from February to April; moreover, it is the least rainy area of the country, with average rainfall around 1,300/1,600 mm per year and savanna-like vegetation.
