Check current weather and air quality (AQI, PM2.5, PM10) for any city — quick lookup with no signup.
This tool runs entirely in your browser — no data is sent to our servers. If JavaScript is disabled, the fully interactive version will not run; enable JavaScript to compute results.
For travel planning, fitness scheduling and just general curiosity, knowing the current weather and air quality of any city is useful. The tool combines a geocoding lookup (turning a city name into coordinates) with weather and air quality endpoints from Open-Meteo, a free public weather API.
The European AQI scale is reported alongside raw PM2.5 and PM10 values. PM2.5 (fine particulates) is the most health-relevant pollutant for everyday exposure — levels above 25 µg/m³ for extended periods are linked to respiratory and cardiovascular issues. PM10 (coarser particulates) matters too but typically tracks PM2.5.
For long-term respiratory conditions or sensitive groups, use the AQI as a planning input — high days are not the right ones for outdoor exercise. For everyday use, just compare to your local norms.
The weather data is updated hourly; the air quality data is updated every few hours. For real-time monitoring during a pollution event, use a dedicated app for your region.
Different countries use different AQI scales (EU, US, India, China). The tool reports the European AQI; the raw PM values are universal and you can compare against your local guidance.
Try the English name or a major nearby city. The geocoding works best for cities with consistent English transliterations.
The Weather & Air Quality lives alongside IP Address Lookup on the Network & Web page. That landing page collects every network & web tool Dailiyo publishes, plus the editorial notes on formula sources, review cadence and how each result should (and should not) be interpreted. If a related network & web calculation isn't yet in the collection and you'd like to see it, drop a line via the contact page — the editorial team reviews every request and prioritises tools that come up most often in reader questions.
