About pollen in San Antonio
Grass pollen is the main player in San Antonio today, sitting at a Low level of 2 on the Universal Pollen Index, with the overall reading also at Low. The forecast points to a gradual easing ahead: grass holds at 2 for another day before settling to 1 for the remainder of the five-day window. Tree and weed data aren't available right now, so grass is the only pollen type with measurable counts to track. The grass activity fits the season, as grasses tend to be most active in late spring and early summer, while tree pollen from regional species like oak, mountain cedar, and ash is well past its winter and spring peaks. Ragweed, the area's notorious fall trigger, is still some months off.
