Best time to run today: compare modeled air-quality windows
AirAgora can compare practical forecast windows for a run. Running changes the caution emphasis because exertion can increase ventilation, but it does not secretly rerank the environmental data or make a personal health decision.

The same environmental ranking, clearer exertion context
The engine evaluates complete two-hour windows using concentration-band component severity and the fixed 70/30 score. Choosing running preserves that ranking, so two users looking at the same city and forecast see the same environmental order.
The activity choice changes the caution threshold and explanatory copy. This separates a consistent comparison from individual advice that the product cannot responsibly infer.
Why an endurance activity needs more than one point
A run can span a forecast transition. AirAgora therefore rejects incomplete windows and includes the worst hour in the score. A short clean-looking point cannot hide a sharp change in the next hour.
The result should still be adjusted to your actual duration and route. A model grid cannot describe every roadside, tunnel, trail, hill, indoor track, or smoke plume.
Read the main pollutant as index context
AirAgora selects the main component from compatible pollutant concentrations rather than comparing raw micrograms of PM2.5 with raw nitrogen dioxide or ozone. Concentrations remain available as supporting context.
A named component can explain what controls the aggregate result, but it does not diagnose symptoms or identify the source of pollution in a city. The static page never invents a local causal narrative.
When the whole running window range is elevated
If every practical window reaches the internal poor band derived from provider concentrations, the product says “least polluted available,” keeps caution visible, and links to official guidance. It never turns relative rank into a safe-to-run claim.
During wildfire smoke or another official incident, local public instructions take priority. The modeled grid may lag or smooth a rapidly moving plume.
A repeatable pre-run checklist
Confirm the city and timezone, inspect the source timestamp, read the OpenWeather scale and category, compare adjacent hours, and note whether the result is stale or incomplete. If conditions are similar, choose based on logistics rather than false decimal precision.
Browser geolocation is click-only. Saved locations and custom threshold automation require an account, but the public running comparison and severe-event caution remain accessible.
- Check the route as well as the city.
- Avoid interpreting one category as a diagnosis.
- Look for changing conditions across the full outing.
- Follow official warnings during severe events.
- Use professional guidance for individual medical questions.
Direct answers
Frequently asked questions
Does running change which window AirAgora selects?
No. Activity changes caution copy and thresholds but not the deterministic environmental ranking.
Why might my route differ from the city forecast?
The forecast is a broad modeled grid. Roads, tunnels, valleys, parks, hills, and plumes can differ locally.
Does a lower AQI mean running is safe for me?
No. It is a relative public index signal, not individual medical advice or a universal safety guarantee.
What if all running periods are unhealthy?
AirAgora can identify the least polluted complete window but labels the whole range elevated and directs urgent choices to official guidance.
Can I save a running profile?
Yes. Free accounts can save one location and one profile; Premium raises those limits and adds longer planning and richer alerts.
Does the tool use live station data?
AirAgora uses modeled OpenWeather forecasts distributed through the official OpenWeather API.
