Thailand has two distinct seasons. From November to April the weather is consistently sunny and dry with temperatures at around 30°C degrees. The predominantly light to moderate northeast winds are ideal for sailing. From May to October the southwest winds pick up and are sometimes quite strong with occasional squalls. Weather conditions during this period are generally good. Although you can expect rain showers but they tend to be short lived. Winds blow from 5-20 knots over the two seasons.
