Why it ranks here

Unusually bad for Harare. The last 7 days averaged 28.7 µg/m³, about 2.9× its typical day (9.9). A jump like this usually has a short-lived cause: likely smoke from fires, dust, or stagnant weather trapping local emissions.

Likely fire smoke. On Sep 29, when Harare averaged 37.1 µg/m³ (its typical day: 9.9), NASA satellites detected 557 fires within 300 km (167 within 100 km). Smoke from those fires is a likely contributor; we don't check which way the wind blew, and mapped smoke can be high above the ground.

Seasonal. Over the past year its worst months were September, averaging up to 39.6 µg/m³ against 4.4 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

Based on Harare's own measurements, with fire detections from NASA FIRMS and smoke maps from NOAA HMS; causes are the usual kinds for a pattern like this, not a confirmed source.
