About pollen in San Antonio
Weed pollen is the main presence in San Antonio today, though it remains at a low level overall. Grass is barely registering, sitting at a very low mark that most people won't notice at all. Taken together, conditions are mild, and only those with a strong sensitivity to weed pollen are likely to feel any effect. Looking ahead, the pattern should hold steady through the next several days, with weed staying low and grass continuing to be a non-issue. This lines up with the seasonal shift into late summer, when oak, elm, and other spring-blooming trees have long finished releasing pollen and attention naturally turns to weeds like ragweed as they build toward their fall peak. For now, though, San Antonio's air remains fairly easy to breathe.
