Tonnr: Surf Forecast & Alerts

Tonnr is the surf forecast that tells you when your spot is working. An alert is a single sentence Tell Tonnr what your spot needs: swell size, period and direction, wind and tide. It watches the forecast for you and lets you know when it all lines up, the night before or as it kicks off, by push notification, email, or both. Before you save an alert, you see when it would go off over the coming week. No more checking the forecast every morning. Swell and wind on one map The ocean is colored by wave height, with arrows showing which way the waves are heading. Tap a live buoy to see what the ocean is actually doing, right next to what was forecast. Wind stations show what's blowing on the coast, and every surf break opens its forecast, tide, guide and reports. Search any break or buoy by name. Every spot at a glance Open a break and get the sea right now in one sentence, then the next 7 days, hour by hour if you want: swell, wind and weather, with the tide curve and high and low tide times. Offshore or onshore? Where a break's orientation is known, the wind is read against the way it faces. Simple, Classic or Complete: you choose how much detail you see. Your spots stay yours Drop a pin where the wave breaks and give it a name: your spots are private by default. Sort your spots, surf breaks and buoys into lists, and share a list with a single link, with a password if you like. Nobody needs an account to open it. Your surf log Log a session in a few taps, or start one as you paddle out and keep the timer on your Lock Screen. Rate it, add your photos and clips, and Tonnr keeps what the ocean was doing. After a few good sessions at a spot, it shows you the conditions you like there, and one tap turns them into an alert. The waves right now Surfers post photos and videos of a break as it is. Each report is checked before it shows: shot at the break, in the last two hours, and actually showing the waves. Save a break to a list and you'll hear when a new report comes in. Guides written by locals Each break has a guide written by the people who surf it: the kind of wave, the tides, swells and winds it likes, how to get there, where to paddle out, what to watch out for. A line shows to everyone once surfers who saved the break, or a moderator, confirm it. On your Home Screen and Lock Screen Home Screen widgets show the sea now at one of your saved places, the next few hours, or your first favorites, and the sea now fits on your Lock Screen too. Turn on Live Activities, and when your spot starts working it shows up on your Lock Screen and in the Dynamic Island instead of a notification. No account needed for the map Buoys, breaks, forecasts and tides are open to everyone. An account keeps your spots, lists, alerts and sessions. Free, for real No subscription, no ads, nothing sold, and analytics only if you say yes. Tonnr is open source under the AGPL, and every number comes with its source: public buoy and wind-station networks and open forecast models, each credited with its license.
