Local Environmental Conditions
At Stony Point Campground, this area, in the wider area, has the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze. Seasonal timing here generally tracks the wider region, give or take a week or so. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
Around Stony Point Campground, water-edge hazel and willow are usually the first allergenic trees active here, topping out well before most other trees start releasing pollen, around February and March. Grass pollen takes over next, building to a peak around June, and then ragweed picks up the slack, running from mid-August through October.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Stony Point Campground 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 Stony Point Campground, 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. |
