Amazing work ! May I ask where do you get the data source ?

The same source as any other forecast-related websites. For wind, temperature, waves, etc there is just THE ONE: https://en.wikipedia.org/wiki/Global_Forecast_System

There is a very big industry build on it. All are happy this data is complex, but very complete and very free :-)

I've long pondered about accurate hyperlocal (200m?) terrain/wind/tidal models for inshore yacht racing - including measuring the frequency & direction of shift, and combining forecasting/modelling with live readings from local weather stations.

Most harbours have fairly accurate bathymetry data, and accurate terrain data is available. Wind data, and the wind & tide flow modelling is the complicated part -- afaik most data is only accurate to 10-20km?
