Climate:
The archipelago of the Bahamas is stretched along a northwest-southeast axis: the northernmost islands are located to the east of Florida, while the southernmost ones are located to the northwest of Haiti. The climate is tropical, with a hot and rainy season from May to October (in which, however, the breezes temper the heat) and a cooler season from November to April, which is felt more on the north-western islands. In general, the best time to visit the Bahamas is the dry season, from late November to mid-April. However, on the north-western islands, from December to March the temperature is often not high enough for a beach holiday, and sometimes there are also some cool and windy days. On the southernmost islands, however, and in particular in Inagua, the winter is warm enough to enjoy the sun and the sea, while on the northernmost islands you may prefer April and May (though in the latter month the rains are a bit more frequent).
From May to October, the weather is hot and muggy, and thunderstorms can be intense (at least on the northern islands), although the sun is still frequent. If you want to choose the summer, the month of July is preferable both because there's a relative decrease in the rains (though this not happens in Nassau and on the north-westernmost islands) and because hurricanes are less likely than in August.
