Works for any place with stations nearby; free, no signup. ## Air quality and UV near a place Each dot is a monitoring station, coloured by its air quality index. Readings from official and research monitoring stations, collected by [OpenAQ](https://openaq.org/), within 25 km and from the last three days. The AQI uses the US EPA scale on the latest hourly particle reading, so it can differ from an official 24-hour figure. UV forecast from [MET Norway](https://api.met.no/) (CC BY 4.0). Your position is rounded to about 1 km before it is sent. ## Air quality index levels | US AQI | Level | What to do | | --- | --- | --- | | 0–50 | Good | Enjoy the outdoors as usual | | 51–100 | Moderate | Unusually sensitive people may limit long, hard exercise outside | | 101–150 | Unhealthy for sensitive groups | People with asthma, heart or lung disease, older adults and children should take it easier | | 151–200 | Unhealthy | Everyone should cut down hard exercise outdoors | | 201+ | Very unhealthy to hazardous | Stay indoors with windows closed if you can | The index is worked out from PM2.5 and PM10 using the US EPA breakpoints revised in 2024, taking whichever is worse. Official indexes average particles over 24 hours, so a short spike, such as smoke from a bonfire, shows higher here than in a daily report. ## WHO air quality guidelines | Pollutant | WHO guideline | Main sources | | --- | --- | --- | | PM2.5 | 15 µg/m³ (24-hour) | Traffic, wood burning, industry, wildfire smoke | | PM10 | 45 µg/m³ (24-hour) | Dust, construction, road and brake wear | | NO₂ | 25 µg/m³ (24-hour) | Road traffic, especially diesel | | Ozone | 100 µg/m³ (8-hour) | Forms in sunshine from other pollutants | The World Health Organization tightened these levels in 2021. Many cities are above them on some days even when the national index says the air is fine, so a reading above the guideline is a nudge to take it easy, not a reason for alarm. ## UV index and sun protection - **0–2, low:** little risk for most people. - **3–5, moderate:** wear sunscreen, a hat and sunglasses, and seek shade around midday. - **6–7, high** and **8–10, very high:** SPF 30 or higher, cover up, and stay in the shade in the middle of the day. - **11 and above, extreme:** unprotected skin can burn in minutes; avoid the midday sun. ## Frequently asked questions What is the air quality near me today? Press "Air quality near me" to use your location, or search any place. The tool finds the monitoring stations within 25 km that reported in the last three days, shows the air quality index from the nearest one with particle readings, what it means for outdoor activity, each station's pollutant levels and the UV index. What is a good AQI? On the US scale, 0 to 50 is good and 51 to 100 moderate; above 100 the air is unhealthy for sensitive groups such as people with asthma, older adults and children, and above 150 it is unhealthy for everyone. Why does this differ from my weather app? Many apps show a computer model forecast for an area several kilometres across. These are measurements from real stations, so they are exact for the station's spot but can differ a few streets away, and the index here uses the latest hourly reading rather than a 24-hour average. Why is there no station near me? Monitoring networks are dense in cities in Europe, North America and much of Asia, and sparse in rural areas and some countries. If nothing has reported within 25 km in the last three days, the tool says so rather than guessing. When do I need sun protection? When the UV index is 3 or more. In the UK and northern Europe that is common from about April to September around the middle of the day; in Australia and New Zealand, UV is high or extreme on most summer days and can be moderate even in winter. ## Related tools [ ### Sunrise & Sunset Daylight and golden hour ](https://getmylocations.com/sunrise-sunset)[ ### Fire Map Wildfires and smoke sources nearby ](https://getmylocations.com/fire-map)[ ### Flood Warnings Live flood alerts (England) ](https://getmylocations.com/flood-warnings)[ ### My Location Where you are right now ](https://getmylocations.com/my-location) AA Written by ### Ahmed Anwar Senior software engineer in Karachi.
