Tropical savanna climates are most commonly found in
Africa,
Asia,
Central America, and
South America. The climate is also prevalent in sections of northern
Australia, the Pacific Islands, in extreme southern
North America in
south Florida, and some islands in the
Caribbean. Most places that have this climate are found at the outer margins of the
tropical zone, but occasionally an inner-tropical location (e.g.,
San Marcos,
Antioquia,
Colombia) also qualifies. Similarly, the Caribbean coast, eastward from the
Gulf of Urabá on the
Colombia –
Panamá border to the
Orinoco river delta, on the Atlantic Ocean (ca. ), have long dry periods. The extreme is the BSh climate (see below), characterized by very low, unreliable precipitation, present, for instance, in extensive areas in the
Guajira, and Coro, western Venezuela, the northernmost peninsulas in South America, which receive < total annual precipitation, practically all in two or three months. This condition extends to the
Lesser Antilles and
Greater Antilles forming the Circumcaribbean dry belt. The length and severity of the dry season diminishes inland (southward); at the latitude of the Amazon river—which flows eastward, just south of the equatorial line—the climate is Af. East from the Andes, between the arid Caribbean and the ever-wet Amazon, are the
Orinoco river
llanos or
savannas, from where this climate takes its name. Sometimes
As is used in place of
Aw if the dry season occurs during the time of higher sun and longer days. This is typically due to a rain shadow effect that cuts off ITCZ-triggered summer precipitation in a tropical area while winter precipitation remains sufficient to preclude a
hot semi-arid climate (
BSh) and temperatures in the summer months are warm enough to preclude a
Mediterranean climate (
Csa/Csb) classification. This is the case in parts of
Hawaii, East Africa (Mombasa, Kenya, Somalia), Sri Lanka (
Trincomalee) and southeast
India, for instance. On coastal regions of Northeastern Brazil (from
Natal to
Salvador), it is rainy roughly from March to August due to
easterly wave disturbances. The difference between "summer" and "winter" in such tropical locations is usually so slight that a distinction between an
As and
Aw climate is trivial. In most places that have tropical wet and dry climates, however, the dry season occurs during the time of lower sun and shorter days because of reduction of or lack of
convection, which in turn is due to the meridional shifts of the
Intertropical Convergence Zone during the entire course of the year, based on which
hemisphere the location sits. ==Some examples of tropical savanna climates==
