The weather on St Martin is awesome. It is, on average, 80-85 degrees all year round with gentle trade winds which keep the humidity low. The only deviation is in the summer when water temperatures rise. This consistent weather with blue skies and clear waters bring smiles to the faces of St Martin visitors. Water temperatures range from 78-80 degrees in the winter and 82-84 degrees in the summer. The winds blow a fairly regular 15 knots from mid-November to mid-April, and in the summer thermal effects and tropical waves frequently bring a bit stronger drafts. As in all tropical environments, brief rain showers are to be expected. While there is no rainy season, hurricane season for the entire Caribbean is Jul - Nov.
