I discovered surfing last year in my early 40's its been a journey and a half and more fun than taking up golf at my age.

SwellSlots squeezes swell height, period, wind speed/direction, and tide state into a color-coded weekly grid. One glance tells you when conditions are 'good' for the next few days.

I wanted it to look completely different to what was out there (UI wise), as most of the forecast apps looks very clinical and cold.

Some technical details:

- SvelteKit + TailwindCSS 4, deployed on Hetzner (LOVE their cloud-console-ux! So simple)

- 2,000+ surf spots worldwide (sourced via a separate AI-assisted pipeline I call "Surf Scout" — got ~80% accuracy, rest is manual curation)

- The spot database was its own challenge — Google Maps couldn't distinguish surf beaches from swim beaches, and LLMs got about 75–80% of the way there

I'd really appreciate feedback on:

- Is the grid scannable enough on first visit?

- Any surf spots missing from your area?

- What else would you like to see?
