Birgit Hackl and Christian Feldbauer on SY Pitufa have compiled this virtual, interactive global wind atlas which summarizes the weather forecasts they have used on Pitufa since they began their cruising adventure in 2011.
Unlike classical pilot charts, this atlas is based on satellite data (uniformly-sampled, unbiased). It visualize world-wide ocean wind data from the SeaWinds scatterometer onboard the QuikSCAT satellites monthly-averaged over ten years. It shows prevailing wind directions and speed for each month and is a great tool to plan passages.
It also includes weather bulletins, surface-analysis charts, cyclone warnings, El-Niño discussions, and of course all Saildocs codes. It also embeds all those current forecasts, so it’s a convenient all-in-one weather site for cruisers.
