About pollen in San Tan Valley
Pollen levels in San Tan Valley are quiet today, with both grass and weed pollen sitting at the low end of the scale. Most people should be able to move through their day without much irritation, and even those who are usually sensitive to grass or weeds are unlikely to notice much of an effect right now. Looking ahead, this calm pattern should hold steady for the next several days, with grass staying low throughout and weed pollen only nudging up slightly toward the end of the stretch. That small uptick fits the season, since late summer into fall is when weeds like ragweed typically become more active in the desert Southwest. Tree pollen from mesquite, palo verde, and olive trees common to the area is well past its spring peak, so it isn't a factor at this point in the year.
