Local Environmental Conditions
The area around the center of New Hamburg is a mix of built-up land and woodland, plus some open grassland. With the Nith River nearby, riverside vegetation along its banks contributes to the local mix. Allergenic trees nearby include maple. Grasses are also a significant pollen source here. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Tree pollen peaks in mid-spring, when the weather warms to around 5°C and maple is in full flower. Grass pollen follows, peaking in early summer and easing off by late summer. Weeds on open ground add a smaller late peak from early summer into early fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the New Hamburg pollen forecast updated?

Does pollen in New Hamburg 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 New Hamburg 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 New Hamburg, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
