About pollen in Round Rock
Round Rock is seeing a fairly even mix of pollen sources today, with tree, grass, and weed all at moderate levels. No single type is dominating the air, but the combination means those with sensitivities may notice some symptoms, particularly with extended time outdoors. It is not an especially harsh day, but it is enough to warrant a bit of awareness if you tend to react to pollen. Looking ahead, levels are expected to ease over the next couple of days before dropping sharply, then ticking back up slightly toward the end of the stretch. Weed pollen, likely from ragweed, is holding a touch higher than tree and grass right now, which fits the season, since late September falls right in ragweed's peak stretch across Central Texas. Tree pollen is unusual for this time of year, as most local varieties like oak, elm, and cedar are typically dormant until late winter, so any tree pollen present now is likely a minor, incidental contributor rather than a seasonal surge.
