Local Environmental Conditions
Here, in the vicinity, the nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees. Birch and oak share the canopy here, birch pollen in particular known to travel far on the wind, in the vicinity. The general pattern described here holds fairly steady across nearby areas with similar land cover.
Along the waterway, hazel and willow release pollen first, climbing steadily from late winter into March. By mid-spring, oak and birch in the woods take over, building to its sharpest point across April and May. Grass pollen takes over next, building to a peak around June, and ragweed later takes the lead from mid-August through October.

How often is the Kawartha Lakes pollen forecast updated?

Does pollen in Kawartha Lakes 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 Kawartha Lakes 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 Kawartha Lakes, 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. |
