Is the air in Stockholm safe today?

Yes. Right now the US AQI in Stockholm is 19, which counts as good. Great air. A perfect time to be outside.

When is the best time to be outside in Stockholm?

Fri 18:00–21:00. That is the cleanest stretch in the next 24 hours, with the US AQI averaging about 20. The worst hour is around Sat 06:00, at 31.

What is the main pollutant in Stockholm?

Ozone (O3). It drives the index right now, at 43 µg/m³. Formed by sunlight acting on traffic and plant emissions. Highest on hot, still afternoons, often downwind of cities.

How does Stockholm's air compare with the WHO guideline?

Within the guideline. Over the next 24 hours PM2.5 averages about 1.7 µg/m³, against the World Health Organization's 24-hour guideline of 15 µg/m³. The other pollutants stay within their guideline levels.

How many cigarettes is a day of Stockholm's air?

Less than a tenth of one. Over the next 24 hours PM2.5 averages about 1.7 µg/m³. By Berkeley Earth's rule of thumb, 22 µg/m³ breathed for a day is roughly one cigarette.

Will air quality in Stockholm improve this week?

Saturday looks cleanest. Its AQI peaks at 31, against 41 on Monday, the worst day in the forecast.

“Next 24 h vs WHO” compares the forecast with the World Health Organization’s 2021 guideline levels: 24-hour means of 15 µg/m³ for PM_2.5, 45 for PM₁₀, 25 for NO₂, 40 for SO₂ and 4 mg/m³ for CO, and 100 µg/m³ over 8 hours for ozone. Above 1× is above the guideline. Levels follow the US AQI, which is far less strict than the WHO, so air rated Good can still be above a guideline.

About this forecast

Forecast from CAMS Europe and global via Open-Meteo: the Copernicus Atmosphere Monitoring Service (CAMS) model at about 40 km resolution (about 10 km inside Europe). Global runs update every 12 hours and European runs every 24 hours. Models smooth out street-level peaks, so busy roads and industrial sites can be worse than shown. Nearby station measurements are independent observations, not adjustments to the forecast. The point forecast uses Open-Meteo’s CAMS products, including a separate carbon monoxide product; it can differ from the globe’s global grid. The AQI rates each hour on the US EPA scale, the same way the map colors it; official daily figures average over 24 hours (8 for ozone), so they can read lower after a short peak. Readings for 59.33°N, 18.07°E, valid 2026-11-13 17:00 UTC.
