Southern live oak
Quercus virginiana
High today, mostly tree pollen.
Last updated September 30, 2026
Pollen is running high across the board in Austin today, with both tree and weed pollen especially active and grass not far behind at a moderate level. Anyone with sensitivities should expect a fairly rough day, as this combination of high tree and weed counts tends to add up and make symptoms more noticeable than usual. The good news is that relief appears to be on the way. After today, levels for all three categories are expected to drop sharply and stay low for a couple of days before creeping back up slightly toward the end of the five-day stretch. This pattern fits the season: with fall underway, ragweed and other weeds are the main drivers of the current numbers rather than tree pollen, which typically peaks in spring when oaks, elms, and ash trees release their heaviest loads. Any lingering tree pollen this time of year is more likely tied to species like Celtis, or Ash producing lower-level, secondary activity rather than a true seasonal surge.
