About pollen in Livermore
Pollen levels around Livermore are quiet today. Both grass and weed pollen are running very low, and neither should cause much trouble even for those who tend to react strongly this time of year. Overall, it looks like an easy day to be outside without much concern about airborne pollen. Looking ahead, the next several days should bring more of the same, with grass and weed levels staying low through the coming stretch. This fits the seasonal pattern for late September, as oak and other spring-blooming trees finished releasing pollen months ago, and grasses have wound down from their late-spring peak. Ragweed and other late-season weeds can still stir up mild activity into fall, but current numbers suggest a calm period overall.
