Windblock helps you keep your schedule clear when it’s windy. This Google Calendar™ add-on monitors trusted public weather forecasts for your ZIP code and automatically blocks off hours that meet your wind threshold. If conditions improve, Windblock adds new events; if the wind drops, it frees the time back up. Your Google Calendar™ always reflects the latest forecast without you having to manage it manually.

Setup takes less than a minute: enter your ZIP, set your wind speed threshold, and choose the hours of the day you want to protect. Windblock creates a dedicated “Windblock (ZIP)” calendar and updates it automatically every 4 hours. You can also refresh instantly from the sidebar with a single click.

Windblock runs entirely within your Google Account™. Your settings are stored securely using Google Apps Script™, and forecast data is retrieved from the public Open-Meteo API. No personal data is exported, sold, or shared.

Avoid double-bookings, stop juggling weather apps, and make sure your Google Calendar™ always leaves space when it’s windy.
