About pollen in Tempe
Pollen levels around Tempe remain mild today, with weeds standing out as the most active source. Overall exposure is low, so most people should get through the day without much irritation, though those especially sensitive to weed pollen may notice mild effects. Grass is present but only at a very low level, and tree pollen is absent entirely. Looking ahead, this pattern should hold steady over the next several days, with weed pollen continuing at a low level and grass staying minimal. Tree pollen is not expected to factor in at all, which fits the season, since desert trees like mesquite, olive, and palo verde typically release their pollen in spring rather than late summer. Instead, this time of year in the Phoenix area is more closely tied to weeds such as ragweed and careless weed, which tend to become more prominent into the fall.
