About pollen in Redwood City
Pollen levels in Redwood City are quiet today, with weed pollen the only type registering any activity, and even that is at a very low level. Most people should be able to move through their day without much notice of it, and those with sensitivities are unlikely to experience more than mild, occasional irritation. Looking ahead, weed pollen is expected to tick up slightly over the next several days, settling into a low but slightly more noticeable range. This lines up with the seasonal pattern for mid-August, as tree pollen from species like oak and birch has long since wound down after its spring peak, and grass pollen from the late-spring and early-summer months has also faded. What remains is the gradual build toward the late-summer and fall weed season, so a slow uptick in weed pollen, including sources like ragweed, is a normal part of the calendar this time of year.
