Local Environmental Conditions
The waterway's edge supports hazel and willow, species known for potent, wind-carried pollen; this sits some 200-300 meters out. The tree cover here leans heavily on oak and birch, both key drivers of spring pollen; this sits as close as 100-200m from this location. A green space where lawn grass and ornamental plantings top up the local grass and ragweed count; this sits barely 200 meters away.
The bank's hazel and willow kick off the pollen season ahead of the rest, starting well before the main spring rush, topping out around March. Oak and birch in the woods pick up where the earlier species leave off, generally peaking somewhere between April and May. Grass pollen becomes the dominant allergen through late spring, peaking in June, before ragweed becomes the more dominant allergen from mid-August into October.

Does pollen in South Euclid 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 South Euclid 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 South Euclid, 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. |
