Check the best time to run, ride or hike with clear reasons. Set an optional daily planning reminder, or unlock full hourly comparison with Pro.
Find a time to run, ride or hike. GoWindow compares the forecast for your activity and recommends a window to head out.
Choose running, cycling, or hiking and an outing length from 1 to 4 hours. Wind, temperature, rain, daylight, and air quality can affect each sport differently, so GoWindow scores them separately.
Start free with one sport at a time
See the best window for today and the available forecast days, plus the reasons behind the recommendation. When another time works for the same outing length, you'll see that option too. Switch your focused sport whenever you like. Check your current location and save one regular place. Adjust your preferences, add a window to Calendar, and check your sport from the Lock Screen widget. No account required. Set an optional daily planning reminder for your chosen time and weekdays, without needing a saved place. Planning reminders start off and you choose when to enable them. Free weather alerts are for Excellent windows only, with a 7-day pause after a qualifying alert.
Plan more with Pro
Compare all available forecast hours before you choose a start time. See all three sports together, save up to 10 places, and set custom weather alerts for up to three places with your choice of sports and score thresholds. Pro weather alerts do not have the Free weekly pause. Check multiple sports from the Home Screen widget.
Monthly and annual subscriptions are available. Eligible subscribers can try the annual plan free for 7 days. Subscriptions renew automatically unless canceled; manage them in your Apple account settings.
About the forecast
Scoring uses air temperature, wind, precipitation and other weather inputs, with air quality when available. Weather forecasts come from Apple WeatherKit and are fetched on your device; air quality requires a network lookup. Road and trail wetness are estimated from precipitation forecasts, not measured surface conditions. Daily planning reminders prompt you to open the app and check the forecast. Scores help you plan, but do not guarantee safe conditions.
iPhone only. Requires iOS 17 or later.
