Walking planner
Best time to walk today: compare complete local forecast windows
The walking tool compares complete two-hour city forecast windows. It supports a practical choice between available periods but cannot measure the exact air along a pavement, park, indoor corridor, or personal route.

A simple comparison with an explainable rule
AirAgora selects one OpenWeather scale from the location, maps each valid hourly value within that scheme, and scores consecutive complete windows. The 70/30 mean-to-worst blend keeps both the overall period and a deteriorating hour visible.
If candidates are materially tied, the earlier period wins. If the best period barely improves on the day’s median, the result says conditions are similar. These rules stop tiny numerical differences from masquerading as certainty.
A walking route can differ from the city coordinate
The data are modeled on a broad OpenWeather grid. Streets beside traffic, covered passages, parks, waterfronts, hills, valleys, and indoor spaces may not match the selected point. AirAgora therefore describes the result as city-level modeled planning.
Choosing device location can make the point more relevant, but geolocation is requested only after a click and still does not turn a grid into a street sensor.
How to interpret the main pollutant
The displayed main pollutant is the largest compatible pollutant-specific concentration-band context for the selected hours, with a stable tie order. AirAgora does not compare raw concentrations with different units to decide which one is “largest.”
That component can explain the aggregate index. It does not prove why the pollutant is present or identify a local source, so city pages stay factual rather than inventing traffic, industry, weather, or seasonal narratives.
Walking on a broadly elevated day
When every complete practical window is poor or unhealthy, AirAgora may still identify the least polluted available period. The label and caution remain explicit because ranking first is not a safety certificate.
Official local guidance takes priority in wildfire smoke, dust, industrial incidents, or other severe events. Public caution is never locked behind Premium.
What to check before using the result
Confirm the city and timezone, OpenWeather 1–5 label, source timestamp, modeled status, and whether the data are current, stale, or incomplete. Compare the hours that cover the whole walk rather than only the start.
If OpenWeather data are unavailable, AirAgora shows unavailable. It never substitutes fixtures, scraping, or another provider in production.
- Check the complete planned duration.
- Notice route-specific surroundings.
- Keep the OpenWeather scale with the category.
- Do not treat a lower window as universally safe.
- Use official instructions during urgent events.

Frequently asked questions
Does AirAgora know the air on my exact walking route?
No. It evaluates a modeled city coordinate. Local streets, parks, buildings, terrain, and indoor sections can differ.
Why does the tool compare two hours?
Two complete hours provide a practical period and keep a change after the first point from being hidden.
Does choosing walking change the environmental ranking?
No. Activity affects caution wording, while the same deterministic score orders the windows.
What if all periods are poor?
AirAgora can show the least polluted available period but says the broader range remains elevated and never labels it safe.
Can I use browser location?
Yes, after explicit interaction. The page never requests location automatically.
Can I save this city?
A verified free account can save one location and one profile. Premium expands limits and planning features.
