Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Columbus today, sitting at a Low level and edging out the broader picture, which also registers as Low overall. Tree pollen has dropped to Very Low, in keeping with late June—the spring surge from maple, honeylocust, plane, elm, and ash is well behind us now. The five-day outlook holds grass steady at Low across the period, so expect little change in the days ahead. This is typical for early summer, when grasses take over as the dominant source after tree season fades. Weed pollen has no data available today, though ragweed generally becomes a factor later in summer and into fall.
