About pollen in Yuma
Weed pollen is the main story in Yuma today, running high and likely to cause noticeable discomfort for those who are sensitive. Grass pollen is present but at very low levels, contributing little to overall irritation, while tree pollen is quiet with no activity to speak of right now. Looking ahead, weed pollen is expected to remain high through the next several days, with only a slight dip midweek before climbing back up. Grass should stay steady at its low level, and trees will likely remain dormant for now. This pattern fits the season well: late September is peak time for weeds like ragweed across the desert Southwest, while tree pollen from species such as mesquite and palo verde typically won't return until spring.
