Recommend you check with "SailSports Belize - Windsurfing" under "Goods & Services" above using the drop down menu. They probably have data on previous November's weather. We have had both great windsurfing around Thanksgiving on the island and no windsurfing around Thanksgiving. It's quite unpredictable that time of year. Many times cold fronts bring the best windsurfing wind Nov-Jan. Chris and Jo that operate SailSports are fine, honest people and will give you straight answers. Happy jibing!
