Magicseaweed shut down in May 2023.
It left a lot of surfers looking for a new forecast. Groundswell was built with them in mind: any coast on earth, clear numbers, and a forecast that's quick to read.
Global coverage, a clean forecast, $4 a month.
Your break, in your language.
Most of the world's surfers don't speak English as a first language. Groundswell is fully translated, from the surf ratings to the tide charts.

Out in the open
We publish our accuracy record.
Every forecast gets it wrong sometimes. Groundswell shows you how often: every day we check our tide times against NOAA's official predictions at 16 US stations and publish the results, station by station, for the past year. Not because we're perfect. Because you deserve to surf on information you can trust, and trust starts with honesty.
See our accuracy record →Multiple sources. One clean answer.
Tide data you can rely on.
Groundswell pulls tide data from NOAA, DFO and the NEMO global ocean model, and shows the best available source for your spot. Where a NOAA station is nearby, a live verification badge shows how closely the forecast matches it.
This one's simple
Check it as many times as you need.
No check limits, on any plan. The ocean changes, and you should be able to look again every time it does.
No cameras
No cams. Here's what you get instead.
Groundswell has no surf cameras. Every spot gets a forecast you can plan with: swell height, period and direction, wind and tides hour by hour for 10 days, plus a rating for each day.
Buoys
Why not just check the buoy?
A buoy tells you what is passing it right now, often far offshore. Groundswell turns open ocean data into a forecast for your break, 10 days ahead, with wind, tides and a rating, including the many spots with no buoy nearby.
