About pollen in Tempe Junction
Weed pollen is the main driver of today's pollen picture in Tempe Junction, with levels running high enough to cause noticeable symptoms for those who are sensitive. Grass pollen is also present at a moderate level, adding to the overall load, while tree pollen is quiet with no activity to speak of. Looking ahead, grass is expected to hold steady at a moderate level over the next several days, while weed pollen is likely to climb even higher before easing slightly toward the end of the stretch. This pattern fits the season: autumn in the desert Southwest is typically ragweed and weed pollen territory, as these plants release pollen through late summer and into fall. Tree pollen, which usually comes from species like mesquite, olive, and ash in this region, remains dormant and isn't expected to factor in until spring.
