Spot advisor is a personalized surf forecast and surf spot rating app. We know it's hard to create a realistic nearshore forecast just from swell, period, and direction. With Spotadvisor you can enter your surf sessions and rate the current conditions. After entering a few sessions, we show a personalized forecast for your favorite surf spots based on marine weather data and your ratings. The more sessions you enter, the more accurate the forecast will be. If you come to a new spot where you haven't entered any sessions so far, you can benefit from the ratings of the other users. Get a surf forecast from many known spots or create your own private spot to get a forecast from every place around the world. Connect with friends and share your sessions and your experience.
