Best time of year?
We are very fortunate here at our location in the Gulf of Thailand to get steady and consistent winds year-round. The southwest monsoon fills in from April to October, bringing occasional rain showers or stronger squalls later in the season - excellent sailing experience, and is replaced with northerlies from November thru March, consistent winds all day, dropping out in the evenings.
While it is not impossible to get a very light or fluky wind day, we average over 300 good sailing days per year. Additionally, our relatively protected top-of-the-Gulf location means we very rarely get wave heights above 1.5 meters, keeping things comfortable aboard the training yachts so we can focus on the lessons of the day.
In all fairness, December to February and May to September would be good choices, but we run successful courses year round. I recommend you join the first available course dates you can fit into your schedule. You will have a great experience with SailQuest every time!
