About pollen in Springfield

Weed pollen is the dominant force in Springfield today, running high enough that sensitive individuals will likely notice symptoms through the day. If you spend extended time outdoors, mornings tend to be when levels are most concentrated, so those with allergies may want to plan accordingly. Looking ahead, weed pollen should hold at a similarly high level over the next couple of days before easing into a more moderate range by midweek. This fits the seasonal pattern for early October, when ragweed and other late-season weeds are typically at their peak before tapering off as cooler weather sets in. Tree pollen from species like oak and maple is not a factor this time of year, as that activity is reserved for spring, and grass pollen remains quiet as well.
