Before a trip, or because family lives there — sometimes you want to know what the air is like somewhere else. Type a city name and you get the air, the weather, and the alerts that country has issued.
Fine dust and ultrafine dust alongside temperature, humidity and wind. It is the same needle gauge used for Korea, so there is no new scale to learn. Whether rain is coming in the next few hours, and how strong the UV is, come along with it.
You can search in any script. Tokyo, 東京 and 도쿄 all find the same place. When a name exists in several countries — Barcelona is in Spain, but also in Brazil, Venezuela, England and the Philippines — the state and country are shown so you can pick the right one.
For typhoons, heavy rain or extreme heat — the things that change what you do today — the country's own weather agency is first and most accurate. So we do not re-judge anything; we pass their announcement through.
These are agencies we actually receive from: the Japan Meteorological Agency (JMA), the US National Weather Service (NWS), Germany's Deutscher Wetterdienst (DWD), Spain's AEMET, the Philippines' PAGASA, and the Italian Air Force meteorological service. The issuing agency is named on screen, so you can go and read their own bulletin if you want to.
The type of alert — thunderstorm, wind, extreme heat, flood — is translated, but the body text stays exactly as the agency wrote it. Some agencies publish only in their own language, so when the text is not in yours we say which language it is. Paraphrasing a warning can change what it means; leaving the original is safer.
Open New York from Seoul and "rain at 3pm" means 3pm in New York. No adding and subtracting hours in your head. The same goes for when an alert expires.
It sounds obvious, and it is a common mistake. Our own air quality timestamp was showing UTC for a while — São Paulo read 12:00 when it was 09:00 there.
Air quality bands differ from country to country. Wherever you look, we colour the gauge using the Korean Ministry of Environment scale. That keeps the feel you already know, and the ceiling of the "Good" band for PM2.5 — 15 µg/m³ — is exactly the World Health Organization's 24-hour guideline, so it holds up internationally.
The numbers may not match that country's official index, so each card says which scale it is using. The full table is on the air quality grades page.
Tap any city below, or search by name in the app for anywhere else.

If you are in Korea, or heading there, the regional pages go a good deal deeper — Seoul · Busan · Jeju. There you can read station by station, ordered by distance.
Yes. Weather abroad works exactly like Korea, and there is no sign-up.
Outside Korea: OpenWeather for weather and air quality, plus alerts from national weather agencies. Inside Korea: AirKorea and the Korea Meteorological Administration directly, which is far more detailed — you can page through the 673 nearest stations.
That agency published only in its own language. We translate the type of alert but leave the body as written — paraphrasing a warning can change what it means. The language is noted underneath.
No. Station-level detail exists only for Korea. Elsewhere you get one reading for the place you are looking at, because the data is published differently.
No. Without it we estimate roughly where you are connecting from, and you can also pick a city from the list or search for one by name.
