About this app

Raw forecasts at your own custom spots.
Originally crowdfunded by surfers worldwide. Over 1 million forecasts served already!

Swell Scope - the surf forecast app with no surf spots. Instead, you add your own custom surf breaks by dropping a pin anywhere in the world.

Use first-of-their kind tools to setup the exposure of your spot in just a few seconds.

Then jump into beautiful charts, animations, and visuals that show you the raw forecast data from the world’s premier weather models.

After your session, auto-import the conditions into your journal and add your own detailed ratings for things like breaking-wave shape and surface cleanliness.

Next time the conditions are similar, you’ll see your own ratings alongside the raw forecast data.

Everything is designed so that you can make the call yourself, instead of relying on mysterious predictions and algorithms.

My hope is to bring back the joy & excitement of learning your local, making the call, and chasing those special sessions.

Over 4,000 people helped beta test Swell Scope throughout 2025! Here are some of the favourite features they helped us develop:

14-Day Forecast
- Raw forecast data from the premier weather agencies. Primary, Secondary, and Wind Swells. Height, period, & direction. Wind strength & direction. Tides. Sunrise & Sunset times. Water Temp. Weather including rain & cloud cover.

Custom Surf Spots - Worldwide
- Drop a pin anywhere in the world to see the forecast there. Use first-of-their kind tools to setup the exposure & inform the app of onshore/offshore directions.

Surf Journal with Auto-Import
- Add your sessions to your journal and all the conditions are automatically imported. Fill out detailed ratings bout breaking wave shape, wind quality, and more

Similar Sessions
- Next time the conditions are similar, see your past ratings alongside the forecast. Use the comparison screen to see for yourself how similar the sessions are and make the call

Trend Charts
- See three full days of charted data for every detail in forecast on a single screen. Spotting trends is easy when you can see so much in one view

Fresh Data
- See which weather agencies & models are being used for every detail in the forecast. Data is updated in the app as soon as it's published by the sources. Most models update every 6-hours, with some being as frequent as hourly!

Ratings and reviews

Really loving it so far. Haven't come across anything I would describe as bugs or glitches. Easy to use and data seems quite accurate. My one suggestion would be if your list of surf breaks could have some sort of flag for what the overall conditions are so you can see the basic assessment at a glance rather than having to open each individual break to view that. You could then open the break to view more in depth data. Or the ability to click next and previous when viewing a break.

swelled energy seems to be a little off at times but everything else is really good. I love the interface, I love the log book, and the whole spot interaction is really good

Looked interesting and so I started using it to log sessions at my local break. I didn't like the way I was supposed to enter the data for each session, it felt patronizing... maybe it's meant for surfers who don't know how to read a swell chart. Anyway, after a month (and maybe 5 or 6 sessions) my free month ended and I thought that was way too soon... after all the app is supposed to learn about my surfing habits and preferences, and that's not going to happen in a single month.

What’s new

New this week...
- Improved similar sessions chart for users with many log entries
- Fixed: Beaufort wind scale usage in log comparisons
