Cuba is actually an archipelago with some 4,000-plus islands and cays dominated by the main island (104,945 square kilometers), which is 1,250 kilometers long—from Cabo de San Antonio in the west to Punta Maisí in the east—and between 31 and 193 kilometers wide. Plains cover almost two-thirds of the island. Indeed, Cuba is the least mountainous of the Greater Antilles, with a median elevation of less than 100 meters above sea level.
Slung beneath the mainland’s underbelly is Isla de la Juventud (2,200 square kilometers), the westernmost of a chain of smaller islands—the Archipiélago de los Canarreos—which extends eastward for 110 kilometers across the Golfo de Batabanó. Farther east, beneath east-central Cuba, is a shoal group of tiny coral cays—the Archipiélago de los Jardines de la Reina—poking up a mere four or five meters from the sapphire sea. The central north coast is rimmed by a necklace of coral jewels limned by sand like crushed sugar shelving into bright turquoise shallows, with surf pounding on the reef edge.
Topography of Cuba
The fecund flatlands are disjoined by three mountain zones, where the air is cool and inviting and the roads dip and rise through very untropical-looking countryside. The westernmost mountains are the slender, low-slung Sierra del Rosario and Sierra de los Órganos, which together constitute the Cordillera de Guaniguanico, forming a backbone along the length of northern Pinar del Río Province. In their midst is the striking Valle de Viñales, a classic karst landscape of limestone formations called mogotes.
The Sierra Escambray rises steeply over west-central Cuba, dominating eastern Cienfuegos and southern Villa Clara Provinces. A third mountain zone, incorporating several adjacent ranges, overshadows the provinces of Granma, Santiago de Cuba, and Guantánamo and spills over into Holguín Province. To the west, the precipitous Sierra Maestra rises steeply from the sea, culminating atop Pico Turquino (1,974 meters), Cuba’s highest mountain. To the east are the Cuchillas de Toa, Sierra de Puriscal, and Sierra de Cristal.
Down by the Shore
Cuba has more than 400 beaches in shades of oyster white, chocolate brown, gold, and taupe. The most beautiful line the ocean side of the innumerable coral cays beaded like pearls off the north coast. Most beaches along the south coast can’t compare; exceptions include Playa Ancón and Cayo Largo. The north coast is indented by huge, flask-shaped bays, not least Bahía de Habana, on whose western shores grew Havana.
Cuba has over 500 rivers, most of them short, shallow, and unnavigable. The principal river, the 370-kilometer-long Río Cauto, which originates in the Sierra Maestra and flows northwest, is navigable by boat for about 80 kilometers. Most rivers dwindle to trickles in the dry season, then swell to rushing torrents, flooding extensive areas on the plains when the rains come in summer. Cuba is studded with huge artificial reservoirs.
Cuba lies within the tropics, though its climate—generally hot and moist—is more properly semi- or subtropical. There are only two seasons: wet (May to November) and dry (December to April), with regional variations.
The island is influenced by the warm Gulf Stream currents and by the North Atlantic high-pressure zone that lies northeast of Cuba and gives rise to the near-constant brisa, the local name for the trade winds that caress Cuba year-round. Indeed, despite its more southerly latitude, Havana, wrote Ernest Hemingway, “is cooler than most northern cities in those months [July and August], because the northern trades get up about ten o’clock in the morning and blow until about five o’clock the next morning.” Summer months, however, can be insufferably hot and humid.
Cuba’s mean annual temperature is 25.2°C, with an average of eight hours of sunshine per day throughout the year. There is little seasonal variation, with an average temperature in January of 22°C, rising (along with humidity) to an average of 27.2°C in July. Nonetheless, in summer the temperature can rise to 32°C or more, and far higher in the Oriente, especially the lowlands of Guantánamo Province (the hottest part of the country). The southern coast is generally hotter than the north coast, which receives the trades. Winds sometimes rip across the central plains in summer, drawn by the rise of hot air off the land.
Midwinter temperatures can fall below 10°C, when severe cold fronts sweep down into the Gulf of Mexico. Atop the higher mountains temperatures may plunge at night to 5°C.
Rain falls on Cuba an average of 85–100 days a year, totaling an annual average of 132 centimeters. Almost two-thirds falls during the May–October wet season, which can be astoundingly humid. Summer rain is most often a series of intermittent showers (or dramatic, short-lived deluges), but downpours and lingering storms are common. Years of relative drought are common.
Central and western regions experience a three- to five-month dry period known as La Seca. February through April and December are the driest months. Nonetheless, heavy winter downpours are associated with cold fronts sweeping south from North America.
The Atlantic coast tends to be slightly rainier than the southern coast. The mountains receive the highest rainfall, especially the uplands of eastern Oriente (up to 400 centimeters fall in the Cuchillas de Toa). The mountains produce regional microclimates, forming rain shadows along the southeast coast, so that pockets of cacti and parched scrub grow in the lee of thick-forested slopes.
Cuba lies within the hurricane belt. August through October is hurricane season, but freak tropical storms can hit Cuba in other months, too. Most hurricanes that strike Cuba originate in the western Caribbean during October and move north over the island. Cuba has been struck by several hurricanes in recent years. In fact, 2008 was one of the worst years in history, with three direct hits in two months: Gustav came ashore on August 30; Ike blasted the country September 7–9, and Paloma hit on November 8. Gustav and Ike displaced two million people and inflicted an estimated US$8 billion in damage (Cuba turned down the U.S.’s offer of US$6 million in rebuilding supplies).
The country has a highly developed disaster preparedness and exemplary civil defense network for evacuations.
