About pollen in Fremont
Pollen levels in Fremont are quiet today. Both grass and weed pollen are running very low, and neither should cause much trouble even for those who are typically sensitive. Overall, it is an easy day to be outside without much concern about airborne allergens. Looking ahead, this calm pattern is expected to hold steady through the next several days, with grass and weed pollen staying at low levels throughout the stretch. This fits the season well, as late September marks a lull between summer grass activity and the tail end of weed pollen, including ragweed, before conditions typically settle further into fall. Tree pollen from local species like oak and birch is not a factor at this time of year, since those trees release their pollen mainly in spring.
