Why it ranks here

Cleaner than usual. The last 7 days averaged 6.7 µg/m³, well below its typical 16.1; rain or wind often clears the air for a while.

Seasonal. Over the past year its worst months were August, averaging up to 25.2 µg/m³ against 9.6 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

Based on Beirut's own measurements; causes are the usual kinds for a pattern like this, not a confirmed source.
