Panama Geography & Climate

Geography

Panama forms the narrow, S-shaped land bridge connecting Central and South America — a bridge that closed only about three million years ago, after which plants and animals crossed in both directions. The Panama Canal spans the whole isthmus in 83 kilometres.

A mountainous spine runs the length of the country, rising to Volcán Barú at 3,474 metres, the highest point in Panama, with the mountain and the land around it under national park protection. Frosts occur in the Cordillera de Talamanca in the west. The Caribbean side, including Bocas del Toro and Guna Yala, is defined by island archipelagos and coral reefs, and the Caribbean coastline has several natural harbours.

The Darién region, in the country's southeast, is Panama's most remote area, cut off from Colombia by the roadless Darién Gap — a nearly impenetrable jungle, and the only break in the Pan-American Highway's otherwise continuous run from Alaska to Argentina. Guerrillas and drug traffickers operate there and have taken hostages.

Panama is one of only three carbon-negative countries in the world, absorbing more carbon dioxide than it releases; the others are Bhutan and Suriname.

Climate Patterns

Panama has a tropical climate. Temperatures are uniformly high, as is the humidity, with little seasonal variation and a small daily range: on a typical dry-season day in the capital the early morning minimum may be 24 °C and the afternoon maximum 30 °C, and it seldom passes 32 °C for long. The Pacific side runs somewhat cooler than the Caribbean, and a breeze usually comes up after dusk.

What changes is rainfall, not temperature — which is why the climatic regions here are drawn by rain rather than by heat. Annual totals run from under 1,300 mm to over 3,000 mm depending where you are, and almost all of it falls in a rainy season that usually runs April to December but varies in length from seven to nine months. Rain is much heavier on the Caribbean than on the Pacific side of the divide: Panama City's annual average is little more than half of Colón's.

Panama lies outside the Main Development Region for Atlantic hurricanes, which is a real advantage, though nearby tropical cyclone activity still adds to the Caribbean side's rainfall.

The Chiriquí highlands around Boquete sit high enough to be markedly cooler year-round — a genuine relief from the lowland humidity.
