On 9 August 2026, Ambrosia is the dominant pollen source in Columbus. artemisia, cypress, and grass are not currently active.

The waterside hazel and willow are consistently first to release pollen each year, building through the tail end of winter into March. Further into spring, the area's oak and birch stands drive the pollen count, peaking in the heart of spring, generally April into May. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed becomes the more dominant allergen from mid-August into October.

The Columbus pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Columbus, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
