Forecast
About pollen in Greeley
Weed pollen is the main driver of today's conditions in Greeley, sitting at a moderate level. Tree pollen is quiet, so anyone with sensitivities is more likely to notice symptoms from weeds than from trees. Moderate levels can bring some sneezing or irritation for those who react strongly to weed pollen, though many people will get through the day without much trouble. Looking ahead, weed pollen is expected to hold steady over the next couple of days before climbing to a higher level later in the forecast window. This lines up with the seasonal pattern for mid-August, when ragweed and other late-summer weeds typically become the dominant source of pollen in the area. Tree pollen, which comes mainly from species like cottonwood, elm, and ash earlier in the year, remains inactive and isn't expected to factor into conditions through the rest of this stretch.
