Where is it?
It looks lovely but I don’t recognise it.

I appreciate your points about grid size and data. However, contour data from the map could be used to predict how the general wind direction within the grid would be deflected by the terrain, eg be deflected around high points and as in crosses the shore line. This would be an addition level of modelling within the current grid rather than the current modelling on a smaller scale.

As a keen and frequent yacht and dingy sailor I find that wind direction and speed are often affected by the local terrain. This can be a navigational and even safety issue as well as significant in racing. Currently your wind directions and speeds are uniform over any localised area. In reality, around, for example, the mountainous islands of the Ionian Sea, Greece or the inlets of my local lake in Devon, Uk, direction and speed are a function of the terrain and local heating effect on it. Your maps includes the contour information that would be required along with the time of day and sunlight forecasts.

Incorporating terrain effects would make Windy invaluable to sailors.
