Raw forecasts at your own custom spots. Originally crowdfunded by surfers worldwide. Over 2 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 5,000 people helped beta test Swell Scope throughout 2025!
