About pollen in Concord
Weed pollen is the main contributor to today's mild pollen picture in Concord, sitting at a low level that most people won't notice much. Grass pollen is even quieter, registering as very low and unlikely to cause any trouble. Overall, it's a calm day for allergy sufferers across the area. Looking ahead, this pattern should hold steady through the next several days, with grass staying very low and weed pollen remaining in the low range. This is typical for late September, as the growing season winds down and weeds like ragweed produce the bulk of what's circulating in the air. Tree pollen from species such as oak and ash is long past its spring peak and isn't a factor right now, so conditions should stay comfortable for those with seasonal sensitivities.
