The Lesser Antilles are situated in the Trade Wind zone with fairly regular winds that seldom exceed force 6. They blow from east, changing direction according on the season to north-east or south-east. They are more regular and fresher from December to May (period of lesser rainfalls). From June to November, the trade winds are irregular and may even abate completely. During summer, breezes from feeble to moderate from west may blow occasionally on the leeward coasts.
Normally, the dry season with less rainfalls is between December and May. In May begins the rainy season, called "the big season of little rains". By the end of September the frequency of rain decreases, followed by the "little season of big rains" until end of November or beginning of December, when the Trade Winds return.
Temperatures vary between 25° and 30° centigrade (77° - 86°F) according to the season, the warmest being summer. Whatever temperature and sunshine are, the impression of heat is mostly due to the presence or absence of the cooling factor of the Trade Winds. The humidity, as all over the tropics, is important, particularly between July to November.
The part on the Atlantic coast could be rough, depending on Trade Wind's force. In the channels between the islands, sea could be choppy. The leeward coast is calm, sometimes with small surge. The tidal range is between 1 ft to 1.5 ft (0.30 - 0.50 m).
