Surf forecasts tell you what the ocean might do. Wave Day helps you understand what those conditions mean for you — at each individual spot. Wave Day combines detailed surf forecasting with a personal Surf Log that learns from the sessions you actually surf. Save a session and Wave Day stores the conditions from that exact time window. As your history grows, it compares those sessions with upcoming forecasts and identifies the conditions that have worked best for you at that specific spot. When similar conditions are expected again, Wave Day can notify you with the spot, day and time that best match your own surfing history. YOUR SURF. YOUR SPOTS. YOUR CONDITIONS. Generic forecasts often classify surfers as beginner, intermediate or advanced. Wave Day takes a different approach. Your ideal conditions are personal — and they can change from one beach to the next. The same swell, wind or tide can produce a great session at one spot and a poor session nearby. That is why Wave Day learns by spot. The more Surf Logs you save, the more useful your personal history becomes. PERSONAL SURF LOG After a session, save it to the corresponding spot and rate your experience. Wave Day keeps the conditions from that period so you can understand what made the session work. • Save sessions by surf spot • Preserve the conditions from each session • Rate your sessions • Compare past sessions with future forecasts • Receive alerts when matching conditions return • Build a different profile for every spot DETAILED SURF FORECAST AT A GLANCE See the forecast by hour together with key ocean and weather information, including wave conditions, wind, tides, water temperature and weather. Wave energy is also included — an important metric for experienced and professional surfers who want more context than wave height alone. SEE HOW WIND AND WAVES HIT THE SPOT A satellite view of each location helps you understand the geography of the beach and how forecast conditions may interact with it. View the spot together with wind and wave direction by time range, making it easier to understand why the same values can behave very differently from one beach to another. SURF SPOTS AROUND THE WORLD Add spots anywhere in the world by searching by name, entering coordinates, or dropping a pin on the map. Save favorites, check upcoming conditions, create a Surf Log for each location, and discover suggested spots worldwide. BUILT FOR EVERY LEVEL — WITHOUT REDUCING YOU TO A LEVEL Wave Day can be useful whether you are starting out, surfing regularly, competing, or practicing another water sport. Instead of assuming that every beginner, intermediate or advanced surfer wants the same conditions, Wave Day learns from your own sessions and from each individual spot. GLOBAL AND PERSONAL Wave Day supports 4 languages, adapts automatically to your device language, and also lets you change language manually. Choose the measurement system and metrics that work for you. You can also discover surfers connected with Wave Day, together with partners, sponsors and brands that are part of the community.
