Local Environmental Conditions
This area, within the local area, has the waterway's edge supports hazel and willow, species known for potent, wind-carried pollen. This area, in the vicinity, has a wooded stretch of oak and birch, with birch responsible for some of the sharpest spring counts. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Hazel and willow by the water are typically first out of the gate, building through the tail end of winter into March. Oak and birch in the woodland come next, through the heart of spring, reaching its high point through April and into May. Moving into early summer, grass pollen climbs to its seasonal high in June, before ragweed becomes the more dominant allergen from mid-August into October.

Does pollen in Cape Croker Park come from nearby or far away?

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 Cape Croker Park 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 Cape Croker Park, 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. |
