Air quality in Xico right now
Right now the modelled US Air Quality Index for Xico, México, Mexico is 51, which falls in the "Moderate" band (up to 100). Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors.
The index is driven mainly by PM2.5, whose own sub-index is 51. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 2.7 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 2.9 µg/m³ against a guideline of 45; ozone is 80 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 7.7 µg/m³ (below the 24-hour guideline of 25).
Also this hour: UV index 5.4, carbon monoxide 235 µg/m³.
NASA FIRMS shows 17 fire hotspots within 300 km in the last day (nearest about 27 km), but particle levels are not elevated enough to point to smoke right now.
