The Cuban climate is tropical and temperate with cool trade winds to provide relief from the heat and humidity. Havana's weather is typical for Cuba; it is generally sunny and hot year round apart from when it is stormy, which is why it is considered a year-round tourist destination. There is not much variation between day and night temperatures along the coast, and average sea temperatures are 77°F (25°C). The rainy season, from May to October, is also the hurricane season, but most hurricanes strike between August and October, while the wettest months in Havana are May and June. Hurricanes are usually more of a problem on the south coast of Cuba and Havana is typically safe from the worst of the tropical storms. Summer temperatures average around 81°F (27°C) with humidity at about 80 percent. Temperatures of about 68°F (20°C) are normal in winter. The temperature very seldom drops below 50°F (10°C) in Havana. The most popular time to visit Havana is in the winter months of December and January but, although avoiding the hurricane season is probably wise, Havana's weather is pleasant for travellers all year.
