Local Environmental Conditions
Nearby, within an easy 150m reach, water here is bordered by hazel and willow, both notable sources of wind-borne pollen. This area, right nearby, about 100-200m away, has woodland where oak stands alongside birch, the latter especially aggressive as an allergen. A stretch of mown parkland where turf and ornamental trees feed local grass and ragweed pollen; this sits barely 50 meters away.
Hazel and willow by the water are typically first out of the gate, reaching its high point sometime in late winter or early spring. Once hazel fades, oak and birch in the woods carry the season forward, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen takes over next, building to a peak around June, before ragweed pollen takes center stage across mid-August into October.

How often is the Cleveland pollen forecast updated?
The Cleveland pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Cleveland come from nearby or far away?
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.
Are pollen levels in Cleveland based on measurements or forecasts?
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 Cleveland, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
