Live oak
Quercus virginiana
Moderate today, mostly grass pollen.
Last updated September 30, 2026
Grass and weed pollen are both running at a moderate level in Sugar Land today, and either could be a source of irritation if you're sensitive to them. Tree pollen is comparatively quiet, sitting in the low range. Overall, it's a fairly typical early autumn day, with outdoor exposure the main factor likely to determine whether symptoms show up. Looking ahead, grass and weed levels are expected to hold steady in the moderate range over the next couple of days before dipping briefly, then climbing back up toward the end of the five-day outlook. Tree pollen should stay low and largely unchanged throughout. This pattern fits the season, as weed pollen, including ragweed, tends to linger into fall, while trees like oak, mulberry, cottonwood, and maple remain mostly dormant until their spring release.
