In Ludwigshafen the air is moderate 🟡 AQI 72. Higher than three hours ago. ☁️ +11 °C · No precipitation · Wind 1 m/s
In Ludwigshafen the air is moderate right now (approximate, US EPA scale). From 10:00 to 23:00 local time the city mean PM2.5 rose from 16.3 to 20.6 µg/m³.
Light wind (1 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). High humidity (99%) possibly makes optical sensors read somewhat higher.
Weather now: cloudy, 11°C, wind 1 m/s, humidity 99%. No major change in the wind is expected in the coming hours.
Written automatically at 23:00 local time (22:00 UTC) from sensor measurements and the weather forecast. Values are approximate; hypotheses are marked.

Daily mean PM2.5 on November 10, 2026 (00:00–24:00 UTC = 01:00–01:00 UTC+1): 20 µg/m³ from 21 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 21 of 77 cities in Germany and No. 314 of 676 worldwide, from the most polluted.
Right now in Ludwigshafen, PM2.5 averages 20.6 µg/m³ — “moderate” on the US EPA scale (approximate, from hourly readings). Mean of 20 sensors from Sensor.Community, readings from 22:55–22:58 local time (21:55–21:58 UTC), summary prepared at 23:00 local time. Median: 10.8 µg/m³; range across sensors: 0.2–140.4 µg/m³.
The current level is “moderate” (US EPA scale, approximate). Unusually sensitive people should consider reducing prolonged or heavy exertion outdoors. This is the standard guidance of the scale, not medical advice.
Highest current reading: 140.4 µg/m³ (SC #54458). Lowest: 0.2 µg/m³ (SC #16775). The list shows every sensor, highest first.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
Over the last 365 days with data, the mean daily PM2.5 in Ludwigshafen was 9.4 µg/m³ — 1.9 times the WHO annual guideline (5 µg/m³). Over the last 30 days: 11.3 µg/m³. From Atmy's archive of daily city means.
In Atmy's daily archive, the cleanest month of the last year was September 2026: 4.4 µg/m³ on average.
The most polluted month of the last year was January 2026: 19.8 µg/m³ on average.
From November to March the mean daily PM2.5 was 14.9 µg/m³, from June to August 6.1 µg/m³ (last 365 days).
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
