Plan when to head outdoors with a forecast that fits the time you expect to be outside.
Outdoor Window is a weather planner for running, cycling, motorcycling and outdoor workouts. See the next 48 hours, choose a 1–8 hour window, and compare forecast conditions across the time you plan to be out.
Seven separate forecast lanes
• Heat index
• Air quality
• Rain
• Wind gusts
• UV
• Temperature
• Daylight
Drag the time-window bracket across the chart to review the highest forecast value for each metric in your selected window. Check condition bands and compare start times using separate suggestions for lower heat, cleaner air, drier conditions or calmer wind. Each metric stays separate—there is no combined score that hides what is driving the forecast.
Made for your activity
Choose the sports you care about and focus on the conditions that matter to you. Adjust the planned window from 1 to 8 hours, switch between °C and °F or km/h and mph, and use light, dark or system appearance.
Understand the forecast
See each forecast’s source, type, issue time and freshness. Weather and air-quality values are forecasts, not measurements at your exact location. Air quality is model-based and may not reflect local monitor readings. The heat-index calculation assumes shade. Forecasts cannot show every on-the-ground condition, such as road surface, wet patches or fog.
Privacy and limitations
Your phone sends forecast requests for the place you check. Outdoor Window has no accounts, tracking or app-owned server. It compares forecast conditions to support planning; it does not say any time is safe and is not medical advice or a safety rating.
