Local Environmental Conditions
Located at a lakeside park on Lake Champlain, Point Au Roche State Park sees vegetation and pollen exposure consistent with Plattsburgh more broadly, following the same seasonal pattern as the surrounding area. As with most sublevel sites, local landscaping can shift counts slightly from the citywide average.
Point Au Roche State Park follows Plattsburgh's established pollen calendar, beginning with maple and elm from March before birch and oak takes over and peaks through April and May. Grass pollen rises through June and July, and a modest weed pollen tail continues into September. Cold winters give way to a fast, concentrated spring pollen ramp-up across the region, a pattern felt across this part of Plattsburgh.

Does pollen in Plattsburgh 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 Plattsburgh 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 Plattsburgh, 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. |
