This has been my go-to for sailing conditions for a while. I used other sites before it (Predict Wind, Surf Watch), but Windy is fast and responsive and usable on a phone. The data for sites like these all ultimately come from the same sources (the big weather models) so the differentiators in this space are mostly in the user experience.
