About pollen in Fremont

At this point in the season, Fremont typically sees a lull in pollen activity. Early-to-mid October tends to fall between the tail end of weed season and the long winter quiet that settles in before trees begin releasing pollen again, so most people can expect a mild day with little in the way of airborne pollen to cause symptoms. Looking ahead, conditions should remain calm through the week, continuing the seasonal pattern for this time of year in the Bay Area. Grasses have mostly finished for the year, and ragweed and other late-summer weeds are fading as the weather cools. The next real shift usually comes in late winter and early spring, when trees common to the area, such as oak, birch, and olive, begin to release pollen again.
