Find a better time for fresh air
Is now a good time to open the windows or head outside? OpenWindow turns local weather and air-quality data into practical guidance, with hourly outlooks to help you choose a better time.
iPhone, iPad, Mac, Android, Windows, Linux
- Two recommendations. Separate guidance for opening your windows and for going outdoors, based on temperature, humidity, precipitation, wind, visibility, UV, and air quality.
- Look ahead by the hour. Find a more comfortable time later in the day.
- Choose your location. Use optional device location or search for a place manually.
- Make repeat checks easy. Save a default location and your preferred units.
