How can we help?

windr pulls forecast data directly from the official US government weather service — the same underlying data professional mariners rely on. Forecasts are updated every few hours as new model runs complete.

windr shows a 7-day hourly forecast for your selected location, broken out by period so you can quickly assess the best windows for your sail.

Your most recently viewed location is remembered automatically between sessions. Full multi-location bookmarking is on the roadmap — if that's important to you, let us know at the contact below and it'll move up the priority list.

windr displays wind speed in knots — the natural unit for sailing. This reflects how the app was built: by a sailor, for sailors.

windr is a Progressive Web App (PWA) and will cache the last-loaded forecast for offline reference. A live internet connection is required to pull fresh forecast data.

On iOS (Safari): tap the Share icon → "Add to Home Screen." On Android (Chrome): tap the menu → "Add to Home Screen" or look for the install prompt in the address bar. windr installs as a full-screen app with no browser chrome.

Different apps may use different forecast models (GFS, NAM, HRRR) or interpolation methods. windr uses the official US government marine forecast. Small discrepancies between apps are normal — always cross-reference before heading out in marginal conditions.

Please email us at [email protected] with a description of what happened, what you expected, and your device/browser. Screenshots are always helpful. We take bugs seriously and will respond promptly.
