SailFlow is the ultimate Android application designed for sailors, racers, and coastal enthusiasts who demand precise meteorological data. Whether you are navigating open waters or cruising near the shore, having access to real-time local weather and live wind reports is essential for a safe and enjoyable experience. The app leverages a vast network of over 65,000 proprietary Tempest Weather Systems to deliver hyper-local conditions exactly where you sail.
With exclusive stations placed on near-shore markers, buoys, piers, yacht clubs, and key waterfront locations, SailFlow ensures comprehensive coverage of your favorite sailing areas. The core of SailFlow’s accuracy lies in its proprietary Tempest Rapid Refresh Model, which generates the most reliable Nearcast predictions available. This system supplements its own data with information from major government agencies, including NOAA, NWS, AWOS, ASOS, METAR, and CWOP.
By combining proprietary hardware with public domain forecasts, SailFlow creates a complete weather view that includes radar, forecast maps, and customized alerting. The app provides ground truth observations using haptic rain sensors, sonic anemometers, and local barometric pressure sensors deployed at marinas and beaches. For those who love detailed data, SailFlow offers live wind flow maps augmented by advanced quality control from current station reports.
