# Weather — Arelo

Arelo surfaces relevant weather conditions on the stop detail page so you know what to expect while you wait.

[Arelo](/) / [Docs](/docs) / Weather

## Weather data source

Arelo uses **Open-Meteo** to fetch weather conditions for each stop location. Open-Meteo is a free, open-source weather API that requires no account or API key and does not receive your location data.

## What is shown

Weather is surfaced as ambient context on the stop detail page, not as a forecast. The goal is to give you just enough information to know what to expect while you wait. Arelo shows:

- **Rain or snow probability:** how likely precipitation is at the stop
- **Sunset time:** useful for evening commutes
- **Heat advisory:** shown when temperatures are unusually high
- **Wind alert:** shown when wind conditions are notable

Arelo does not show a current temperature, condition icon, or hourly forecast. Weather context is intentionally minimal.

## Privacy

Weather requests are made using the coordinates of the stop you are viewing, not your precise location. No personally identifiable information is sent to Open-Meteo. See our [Privacy Policy](/legal/privacy-policy) for full details.
