Live oak
Quercus virginiana
Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the main presence in Mesquite today, sitting at a low level that most people will not notice unless they are particularly sensitive. Tree pollen is essentially quiet right now, so any irritation you feel outdoors is more likely tied to weeds than anything falling from oaks, ash, or other local trees. Looking ahead, expect this pattern to hold steady over the next several days, with weed pollen staying at a similar low level and tree pollen remaining minimal throughout. This fits the season well: the heavy tree pollen from species like oak, mulberry, ash, celtis, and Chinese tallow (Triadica) wrapped up months ago, and grass season has also wound down. Weeds tend to be the main contributor to late-summer air, with ragweed and similar plants gradually becoming more active as fall approaches, so it is worth keeping an eye on that trend in the coming weeks.
