The Bahamas has a tropical savanna climate (Köppen climate classification Aw). The conditions are hot and humid throughout the year. The Bahamas is an island country within the Lucayan Archipelago in the Caribbean. The U.S. state of Florida lies in the northeast, Cuba, and Hispaniola Island are in the southwest, and the Turks and Caicos Islands are to the southeast of the Bahamas. Andros Island is the largest, followed by Great Inagua in the far south. Nassau lies in New Providence, while Freeport, the second-largest city, lies in the Grand Bahama Island. The tropical location has bright sunshine and an equal duration of days and nights throughout the year. Northeast trade winds reduce the effect of the tropical sun. The tropical location, the Gulf Stream, and the Atlantic Ocean chiefly influence the climate.

The Bahamas is an island-chain spread over 500 miles in the Atlantic Ocean and consists of more than 700 islands and cays. The archipelago's location is around the Tropic of Cancer. The Tropic of Cancer Beach in the Little Exuma Island in the Bahamas straddles the Tropic of Cancer. The landscape is mostly flat, with a very low elevation. Ridges rise mostly between 15 meters and 20 meters. The land is primarily rocky or mangrove swamp. Rocks are of limestone type, but the islands have a foundation of fossil coral. Much of the land is under low scrub cover. Pineyards grow on the northern islands, while the southern islands have tropical hardwood. The freshwater resources are in the form of a few lakes and only one river on Andros Island. Mount Alvernia, on Cat Island, is the highest point in the Bahamas at 64 meters above sea level.

The Bahamas has a wet season from May to October and a dry season from November to April. The wet season is hot, cloudy, and oppressive. The average daily temperatures range between 23.9°C (75°F) and 27.8°C (82°F) in the warmest months of July and August. More than 70% of the rainfall occurs between May and October. The wet season sees heavy rainfall and tropical storms. The Bermuda High brings a warm, moist tropical airflow from the southeast. The temperature increases and precipitation decrease from the northwest to the southeast. The dry season is mild, humid, and windy. The average daily temperatures range between 20°C (68°F) and 24.4°C (75.9°F) in the coldest months of January and February. Northeast trade winds and westerlies from the North American mainland affect the Bahamas in the dry season. Cold air masses push down temperatures up to 10°C (50°F) in Freeport and Nassau. Every month has a daily mean temperature above 17.2°C (63°F).
