Nicaragua has two distinct seasons: the dry summer (verano) and the wet winter (invierno). Summer (Dec–April) can be extremely hot and often uncomfortably dry, but it's usually regarded as the best time to visit. Fewer travellers come in the rainy season (May–Nov) – which alone could be a reason for choosing to put up with the daily downpour. On the Pacific coast, rain often falls in the afternoons from May to November, although the mornings are generally dry. The central mountain region has a cooler climate with sporadic rainfall all year, while the Atlantic coast is wet, hot and humid year-round, with September and October the height of the tropical storm season.
