Local Environmental Conditions
Around Forest Hills Resort, the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring; this sits within easy reach. Here, just around the area, woods composed largely of oak and birch, a combination tied to sharp spring pollen spikes. Local readings for the surrounding area tend to follow this same general pattern.
For Forest Hills Resort, oak and birch in the nearby woodland follow in mid-to-late spring, reaching maximum intensity across the April-May window. Hazel and willow by the water are typically first out of the gate, usually peaking sometime between late winter and the end of March. Grass pollen climbs toward a June peak, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

Does pollen in Forest Hills Resort 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 Forest Hills Resort 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 Forest Hills Resort, 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. |
