Your best window to ride
Wind, gusts, precipitation timing, and temperature — scored for cyclists who need to know before they clip in.
Why cyclists need GoWindow
Sustained wind and gusts are separate
GoWindow scores forecast wind speed and peak gusts separately. A steady breeze and a gusty hour affect the cycling score differently.
Strong gusts get their own penalty
Gust speed contributes to the hourly score and can apply an unsafe-gust penalty when it climbs.
Rain around your ride matters
GoWindow uses precipitation forecasts around your chosen hour to estimate wet-road risk. It does not measure the road surface.
What the cycling score weighs
Sustained wind is one of the largest inputs in the cycling score.
Forecast gust speed is scored separately and can apply an unsafe-gust penalty.
Air temperature is scored against your cycling preference; estimated WBGT handles heat stress separately.
Precipitation forecasts before and during the window help estimate wet-road risk; actual road conditions can differ.
Sticky air can lower the score even when airflow helps with cooling.
AQI above the Good band can lower the score when data is available.
When GoWindow helps cyclists
Choosing a morning ride before afternoon gusts build on an exposed route
Deciding whether a windy day is still rideable or genuinely unsafe
Finding a 2-hour gap between rain bands for a lunch ride
Checking tomorrow's forecast to set an early alarm for a long ride

Why Timing Matters More Than Temperature
Most people check the temperature before heading out. The best outdoor sessions depend on a narrow window where several conditions line up — not on one number.
AQI and your lungs: what the air quality number means when you're running
When you run, you breathe ten to twenty times harder than at rest. That changes how air pollution lands in your body. Here's what runners should actually do with the AQI number.
Cycling in the wind: why gusts matter more than the average
How to read wind speed and gusts before a ride, and why the calmest-looking forecast is not always the safest window.
How to choose a cycling weather window
Compare wind, gusts, rain, heat, and air quality across the ride instead of judging one forecast number.
