Live oak
Quercus virginiana
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels in Alief are quiet today. Grass is the only real presence in the air, and it's registering at a very low level, so most people should get through the day without any trouble. Tree pollen is essentially absent right now, which is typical for midsummer once the spring bloom from trees like oak, ash, elm, and celtis has long since wound down. Looking ahead, conditions should stay steady over the next several days, with grass holding at that same very low level and tree pollen remaining a non-issue. This kind of lull is normal for late July, sitting between the spring tree season and the ragweed and weed pollen that tends to pick up later in the fall. For now, sensitive individuals should find outdoor activities comfortable with little pollen to contend with.
