Guatemala has been dubbed the “Land of Eternal Spring,” a name which comes from the climate in the country's mountain regions. The mountains tend to have warm days and cool nights year-round. The temperate daytime weather makes the mountain region a pleasant place to visit at any time, but don’t forget a sweater for the chilly evenings. There are two basic seasons: wet and dry. The wet season is from approximately the middle of May to the middle of October. Wet weather can last for longer in the Petén region, where rains can continue into December. In the rainy season, the downpours do not last all day, but there are daily showers which normally fall in the afternoons. Humidity can also be high during these times. During the rainy season, roads can become more difficult to travel, particularly when you are heading further off the beaten track. The dry season runs from roughly November to April. During these months, temperatures can be very high along the coast and in the Petén area.
