WeatherFlow is a California-based developer and weather instrumentation company focused on wind, marine and outdoor forecasting tools. Their app portfolio — which includes WindAlert, FishWeather, SailFlow, iKitesurf, iWindsurf and Tempest Weather — serves sailors, anglers, kitesurfers and wind-dependent communities with localized forecasts, live observations and map-based visualization. Beyond mobile apps, WeatherFlow builds and supports a growing network of personal weather stations and the Tempest Weather System, which feed higher-resolution data into their services.
The company is notable for bringing hardware and software together: compact sensors connect to cloud services and power real-time layers used across their apps. WeatherFlow’s products emphasize transparent data sources, user-contributed observations and tools tailored to specific sports and maritime use cases. Their apps are often selected by recreational and professional users for wind maps, tide and marine forecasts, and storm monitoring.
