Should you go sailing today? SailWindow answers in one glance, then shows you why. Built by a racing sailor for the hours before you leave the dock, SailWindow puts the official NOAA marine forecast, the nearest buoys, six wind models and a route planner in one app. No account, no ads, no subscription. ONE-GLANCE SAILING VERDICT • Good, Caution or No-Go for the hours ahead, based on wind, gusts, waves, rain and thunder • Tap the verdict to see exactly which limit was crossed and when • Set your own limits for each spot: a dinghy sailor and a 40-footer need different numbers SIX WIND MODELS, SIDE BY SIDE • Animated wind map with GFS, HRRR, ECMWF, ICON, GEM and Météo-France guidance • Scrub through the next 48 hours and tap anywhere for speed and direction • Model table lines up every model's wind speed and direction hour by hour, so you can see when the models agree, and when they don't ROUTE PLANNER FOR DISTANCE RACES AND DELIVERIES • Pick a start and a finish and compare routes from four wind models • Synchronized playback shows every model's boat over the changing wind • Hourly wind along each route, ETA spread and optional GFS ensemble check • Uses a measured J/105 polar. A planning aid, not a navigation system: routes do not avoid land, shoals, currents or waves. NOAA DATA, READ FOR YOU • NWS gridpoint forecast for wind, gusts, waves, wave period, temperature, rain and thunder • The NOAA marine text forecast for your zone, matched automatically and formatted for reading • Active marine warnings and Small Craft Advisories • Nearby NDBC buoys and shore stations on a map, with live wind, waves and pressure • Rain radar with animated recent frames and the official NOAA reflectivity layer MADE FOR WHERE YOU SAIL • Start on your own water: pick from 30 spots in California, Florida, the Gulf, the Atlantic coast, the Great Lakes, Hawaii and Puerto Rico, or use your location • Save more spots, like Point Loma, Key West or your home lake, and switch between them • Notifications when wind, gusts or waves cross your limits, when the verdict changes, or when a marine warning is issued • Dark mode that won't wreck your night vision in the cockpit • On iPhone Duo, the inner screen shows tabs in a side rail and the NOAA forecast beside your numbers Forecasts, alerts and buoy data come from NOAA, the National Weather Service and NDBC, so the full feature set covers U.S. coastal waters and the Great Lakes. The wind map and route planner work anywhere. SailWindow is for planning and situational awareness. Conditions change quickly; always check official sources and local conditions, and carry the required safety equipment.
