About pollen in Tucson
Weed pollen is the most active presence in Tucson's air today, though it remains at a level most people would describe as light. Grass pollen is barely registering and shouldn't cause much concern. For those with sensitivities, this is a fairly easy day overall, with only mild potential for irritation. Looking ahead, this pattern should hold steady through the next several days, with weed pollen staying low and grass continuing to be a minor factor. This lines up with the seasonal calendar for the region: desert trees like mesquite and palo verde finished their heavier pollen release back in spring, and grasses have largely quieted down as summer temperatures peak. Weeds such as ragweed and pigweed tend to become more prominent as late summer moves toward fall, so it's worth keeping an eye on gradual upticks in the weeks ahead, even though today's numbers stay on the calm side.
