Canton pollen forecast — Upper Downtown Canton Historic District neighborhood

On 9 August 2026, overall pollen levels in Canton are moderate. Ambrosia is the main contributor to airborne pollen

On 10 August 2026, pollen conditions in Canton will be different from today, with ambrosia at medium levels, artemisia at low levels

According to the five-day outlook, ambrosia, artemisia, and grass pollen levels will increase later in the week.

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

Late spring sees grass pollen build steadily toward a peak in June, before ragweed becomes the more dominant allergen from mid-August into October. Warmer or wetter years can pull these peaks a week or two earlier or later. This general pattern holds fairly steady across the surrounding county from year to year.

The Canton 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 Canton, 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.
