About pollen in Columbia

Grass pollen is the main driver in Columbia today, sitting at a moderate level (3) and pushing the overall index to moderate as well. Tree and weed pollen are not being reported in the current data. The near-term forecast holds grass steady at moderate for the next couple of days before easing to a lower level (2) through the rest of the five-day window. That gentle downward drift fits the season, as the late-spring and early-summer grass peak gradually fades. Tree pollen, which dominates earlier in spring, is well past its high point now, and ragweed and other weeds typically don't ramp up until late summer and fall.
