About RainOrRun

RainOrRun is a simple, free weather tool built for runners. It answers one question: should I run outside today?

Enter your city or allow GPS access, and you'll get an instant verdict - Go, Maybe, or Don't Bother - based on current precipitation, temperature, wind speed, and severe weather conditions.

How it works

We use the Open-Meteo weather API to fetch real-time hourly forecast data for your location. Our algorithm scores conditions across four factors:

• Precipitation probability and amount
• Temperature (too cold or too hot reduces the score)
• Wind speed
• Severe weather codes (thunderstorms, blizzards)

The combined score gives you a clear verdict plus the best hourly window to run and condition-matched gear recommendations.

Privacy

RainOrRun respects your privacy. We use Plausible Analytics - a privacy-first, cookie-free analytics tool. We don't track you, sell your data, or use third-party advertising trackers.

If you grant GPS access, your coordinates are sent directly to Open-Meteo to fetch weather data. We don't store your location on any server. Your last-searched city is saved in your browser's localStorage so you can quickly check again on return visits.
