I’m doing a similar thing with open-meteo for surf forecasts (for myself primarily)

Only one region, but could quite easily expand. It takes the open-meteo ocean data and combines it with some short and long range weather. Then run a preprocessed refined version of that through an LLM to turn it from quantitative into qualitative. It basically does what I would do in my head.

If you have any ideas, please let me know
