About
SailFlow is a purpose-built weather platform for anyone whose hobby or livelihood depends on the wind. Developed by WeatherFlow-Tempest, it aggregates data from more than 50,000 weather stations around the globe — including the company's own ultra heavy-duty PRO Stations, designed by MIT engineers and strategically placed by professional meteorologists for maximum accuracy. The platform delivers a rich suite of tools: live wind and gust maps, nowcast maps, radar and precipitation overlays (North America), satellite and cloud imagery, sea surface temperature charts, StormTrack forecast maps, and on-site community reports. Users can configure wind alerts so they never miss an optimal session, save favorite locations, and access GRIB data downloads for advanced planning. SailFlow supports a wide range of wind and water sports including sailing, kiteboarding, kitesurfing, windsurfing, surfing, paragliding, and yacht racing. Its tiered model offers a solid free experience with basic maps and station data, while PLUS and PRO subscriptions unlock premium forecasts praised by industry professionals as best-in-class. Available as a responsive web app and native iOS/Android apps, SailFlow keeps athletes connected to conditions wherever they roam.

Pros
- Unmatched Station Density: Over 50,000 weather stations globally — including proprietary PRO Stations — provides hyper-local accuracy that generic weather apps cannot match.

Cons
- Radar & Satellite Limited to North America: Radar/precipitation and satellite/cloud map overlays are only available for North America, limiting utility for international users.
- Best Forecasts Locked Behind Paywall: The highly praised PRO forecasts require a paid PLUS or PRO subscription, which may deter budget-conscious users.
- Niche Audience: The platform is narrowly focused on wind and water/air sports, making it less useful as a general-purpose weather application.
