PredictWind is my go to weather forecast

I race Blokart landyachts internationally, dinghies locally on the Isle of Wight and my Beneteau yacht in the Solent and around the Channel. PredictWind consistently provides the most accurate short, medium and longer term forecasts. The tools such as routeing also work well and the developments such as summaries and iridium link are quality. Pete Newlands, previous Olympian and Fastnet Race winner.

For everything thing from Harbour sail to Ocean crossing

Excellent weather app for everything from harbour weather to Ocean routing. Easy to use. Recently routed us on a perfect passage from Bermuda to The Azores, seamlessly working with my Iridium Go. Then this weekend, checked out the forecast for a Sunday out on Sydney Harbour. Not cheap, but well worth it.

PredictWind accuracy

The tables etc look impressive but are they accurate?

For example we set sail at 6.30 am today 17th June 2018 on a 4.5 hour trip from near Bozburun Turkey to Palamut. During most of the trip we were subjected to heavy rain and impending thunderstorms. Yet there was absolutely no mention of rain by PredictWind. Yet Windguru Pro accurately forecast this bad weather.

Ironically the other forecaster to get it right was the free Navtex service that predicted thunderstorms!
