Local Environmental Conditions
Located near this part of town, this area has a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. Nearby, a short distance from here, woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
Near the bank, hazel and willow lead the seasonal calendar, climbing steadily from late winter into March. By mid-spring, oak and birch in the woods take over, usually peaking from April into May. Grass pollen builds through late spring and peaks in June, followed by ragweed's own peak stretch from mid-August into October.

Does pollen in Glenwoodie Golf Club come from nearby or far away?

Are pollen levels in Glenwoodie Golf Club 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 Glenwoodie Golf Club, 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. |
