Windguru - A good weather forecast for Boating

I love calm seas and gentle breezes. Little waves lapping against the boat's hull is okay. As much as I am able to, I avoid going out to sea when the winds blow greater then 15 knots and waves higher than 0.7m, I'd rather cruise around the sheltered waters off our local waters. Over the years, I have found one website that I totally rely on to make sure I don't get caught off guard. That website is www.windguru.com It is a free to use site and describes accurately the wind and waves in many regions that our local boaters frequent. This is an example of the forecast off Desaru Malaysia. I use this forecast whenever I fish off Horsburgh Lighthouse and up to 60 nautical miles North of the lighthouse. It has served me well all these years.
