High Pollen in San Antonio, TX

About pollen in San Antonio

Weed pollen is the main driver of today's conditions in San Antonio, running high and likely to cause noticeable symptoms for those who are sensitive. Grass is at a moderate level and could add to the irritation, while tree pollen remains low and should be easy to manage. Looking ahead, both weed and grass pollen are expected to ease significantly over the next couple of days before climbing back up toward the end of the five-day window, so anyone affected may get a brief reprieve midweek. Tree pollen is expected to stay low throughout, consistent with this time of year — the region's oaks, cedar elms, and mountain cedar are largely dormant now, with cedar season still a few months off. The bigger story this season is ragweed and other fall weeds, which typically peak through late September and into October, making this a period when weed-sensitive individuals should expect the most noticeable effects.

What to do today

• When driving the car, close your windows and turn the air conditioning system to recirculation mode.
• Keep your windows closed and turn on your air purifier or air conditioning.
• Consider staying indoors during the peak pollen hours (morning and early afternoon).
