Local Environmental Conditions
Located not far off, about 700m out, this area has the waterway's edge supports hazel and willow, species known for potent, wind-carried pollen. Here, a short trip out, around 500m, woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. This park's mix of turf and landscaped trees contributes a modest grass and ragweed pollen load; this sits not far off, about 200-300m out.
Near the bank, hazel and willow lead the seasonal calendar, leading off the pollen calendar, with a peak generally falling in late winter. Oak and birch nearby take over the pollen calendar through mid-spring, topping out in the April-to-May stretch. Late spring sees grass pollen build steadily toward a peak in June, before ragweed pollen takes center stage across mid-August into October.

Does pollen in Westland 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 Westland 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 Westland, 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. |
