Show HN: Windria – Local wind/wave forecasts for sailors visualized in a heatmap

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?

Wave heights are missing. The text is problematic when it mentions the "NAM RAP" model. There isn't such a model, there's the NAM which runs every 6 hours out to 84 hours, and there's the RAP which runs every hour for 18 hours.

This would actually be useful to me in the center of the continental US. I haul big sheds down the highway, and being able to travel on a day with the wind behind me allows me to go 20mph faster.

https://www.windyty.com/ has similar functionality, but in my point of view a much nicer UI

Much nicer visualization than current sites. Will share with my sailing friends.

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

Wow, looking neat.
