Live oak
Quercus virginiana
High today, mostly tree pollen.
Last updated September 30, 2026
Pollen levels in Mesquite are running high today, with both tree and weed pollen strongly active and grass close behind at a moderate level. Anyone sensitive to any of these is likely to notice symptoms outdoors, and the combination of multiple pollen types being active at once may make today feel more intense than a typical fall day. Relief appears to be on the way, as all three categories are expected to drop sharply tomorrow and stay low through the middle of the week before ticking back up slightly toward the weekend. This pattern fits the season: weed pollen, particularly ragweed, is typical for this time of year, while the tree pollen contribution from species like oak, ash, mulberry, celtis, and triadica is a bit less common in early fall and should ease off quickly as conditions calm.
