Cuba is an island located at a latitude very close to the Tropic of Cancer by which receives high values of solar radiation throughout the year resulting in a warm climate. It is oriented east-west and being a long narrow island, its entire territory is exposed to the refreshing trade winds and sea breezes. Cuban climate is usually classified as moderate subtropical, seasonally wet, with marine influence and some parts of the country show signs of semi-continental.
Notwithstanding this, there are specific areas dominated other types of climate such as the upper reaches of the main mountain ranges (Topes de Collantes, Sierra Maestra and less Viñales) or the southern coastal provinces of Santiago de Cuba and Guantánamo where the climate is classified as tropical semi-dry with little rain presence.
Between November and April noticeable climate changes occur due to the influence of continental anticyclone, the passage of frontal systems and extratropical low pressure centers. By contrast, between the months of May and October the weather changes very little due to the influence of the North Atlantic anticyclone, the variations that can occur in this period are easterly waves and tropical cyclones.
