There are not enough fresh measurements for Saint-Girons right now. From 10:00 to 21:00 local time the city mean PM2.5 rose from 1.0 to 6.0 µg/m³. The highest hour was 19:00 with 9.5 µg/m³.

Light wind (2 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). High humidity (89%) possibly makes optical sensors read somewhat higher.

Weather now: cloudy, 13°C, wind 2 m/s, humidity 89%. No major change in the wind is expected in the coming hours.
