I recently completed a 5 week westbound summer sailing cruise around the Great Australian Bight. This was planned last year using the historical data on Windy TV, which is much more relevant than the traditional alternative - Pilot Charts, which are based on the averaged noon reports of mariners going back hundreds of years. Pilot charts are at best issued averaging a whole month, over 5 degree squares. GRIB based data at 3 or 6 hour intervals, day by day, at 1/4 degree resolution provides a far far better tool for understanding how wind systems progress in past seasons. I'm a yachting writer, and reported this beneficial use of Windy TV, but had to add that the restrospective review of data was no longer supported by the site. I'd encourage WindyTV to restore historical data as soon as practical, and to progressively extend it to earlier years. It will become an important resource, not otherwise available to the ordinary sailor.
