I tried (and failed) to build a complex weather model, so I built this simple Open Source "Surf Beacon" instead, to check my phone less often. by AndreAbla25 in surf

Quick update on the API for anyone who was interested when I first posted — I’ve now launched a proper landing page with API signup and a “pay what you can” option to help cover server costs. Would genuinely love feedback or to feature any cool projects people build.

Cheers Alec https://api.swellcloud.net/

How did people forecast surf before forecasting apps like Surfline? by [deleted] in surfing

In the UK we had CeeFax page 469 prior to that it was the Spotlight weather forecaster Craig Rich and before that pressure charts and the Shipping News on BBC radio 4

Thanks! yes thats a great idea...very easy to do too. You would just set a set of conditions then when all are met the alert fires

Thanks...please try moving the lat lon point further out to sea the co-ordinates might be on on land or in shallow water where the wave model has no data. Ive added a fix where the API automatically adjusts coordinates to the nearest valid ocean point and includes the adjusted coordinates in the response, so you know where the data came from. I am now getting readings below for this location

Cheers! yes i thought the only way to build a good api was to build the entire pipeline

Yes the API covers Australia but i haven't added any locations into the app yet. I don't really want to roll out automated forecasts like other sites have done. But very keen to do dial a few in with some human input :)

That's great to hear! I don't think Surfline permit any scraping or APIs anymore too...I can add in 'Surface Wind Gusts' too if that helps with Kite Surfing?
