Live oak
Quercus virginiana
Moderate today, mostly grass pollen.
Last updated September 30, 2026
In Alief today, grass pollen is the most active contributor to the overall moderate conditions, and it may be noticeable for those who are especially sensitive. Tree and weed pollen are both running low, so they shouldn't cause much trouble for most people right now. Looking ahead, grass pollen is expected to hold at a similar moderate level over the next few days, with a brief dip midweek before ticking back up. Tree and weed pollen should stay low throughout, with only minor day-to-day shifts. This lines up with the seasonal pattern for late September, when trees like oak, elm, and ash are largely quiet and grasses can still linger into early fall before ragweed and other weeds typically become more of a factor later in the season.
