Frequently Asked Questions

How does this website work?

We use weather data from OpenWeatherMap to analyze your local forecast—including rain, humidity, wind, and UV index. Based on this, our tool tells you whether it’s a good day to wash your car or better to wait.

For more background, see our About page.

Is this tool accurate?

While no forecast is perfect, we use live data and make a common-sense judgment call based on the latest information. We aim for practical, real-world guidance, not just a basic rain prediction.

Can I use this anywhere?

Yes! This tool works globally. As long as weather data is available for your location, we’ll give you a recommendation.

Is it free?

100% free. We might show ads to help support the site, but using the tool is and always will be completely free.
