Read full description

The MTL SURF app provides live data on river metrics like the water temperature, the level and the debit. According to those metrics, you now have a hint at your fingertips to know wether or not the wave is good. The app also tells you if you should put on your spring suit or your full hooded 6/5 winter wetsuit. You can also watch if those metrics are going up or down one month back with line charts. Make sure to check the app before your next session at Habitat 67 or at "Vague à Guy"!
