GoWindow

Find your best outdoor window to run, ride, or hike.

A thermometer can't tell you when to go out today. GoWindow compares the hourly forecast and picks a window for your sport.

See how it works

For runners, riders, and hikers · 1–4 hour windows

Start free with one sport, your current location, and one saved place.

One answer to one question: when should I go?

GoWindow scores the forecast hours that matter for your sport, not just the temperature.

The window score

Forecast data, turned into a decision.

A single score is useful only when it knows what you are doing. GoWindow changes the weighting for running, cycling, and hiking.

Different sport, different score

Running leans on air temperature and dew point. Cycling scores sustained wind and gusts. Hiking adds UV, trail wetness, and thunderstorm risk. The inputs change with the activity.

More than one number

GoWindow scores air temperature, dew point, sustained wind, gusts, precipitation, visibility, and estimated heat stress separately instead of combining them into a single feels-like value.

The risks a forecast tends to bury

UV load, heat stress, thunderstorm timing, and air quality when smoke or haze are around. If conditions get risky, the score moves.

Three sports. Three answers.

The score changes with the way you move.

Wind can ruin a ride. Dew point can ruin a run. Thunderstorms can end a hike. GoWindow keeps those decisions separate.
