In February, the wind moves to the east and by June it changes to the south-east averaging 10 to 15 knots. In September and October, the trade winds are at their weakest and the weather can be less settled. By November the high pressure system around Bermuda starts to stabilise and 15 to 20-knot breezes become the norm. Immediate weather conditions can be found at http://www.weather.com.
