Local Environmental Conditions
Nearby, close to this spot, river oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species. Woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two; this sits in the wider area. This area, within the neighborhood, has maintained parkland where turf grass and ornamental plane trees add to the local pollen mix.
Along the waterway, river oak releases pollen first, starting well before the main spring rush, topping out around September. Eucalypt and wattle in the nearby woodland follow through late winter and early spring, topping out in the August-to-September stretch. Through spring, grass pollen climbs steadily toward its November peak, and remaining a significant allergen right through summer until it eases in February.

How often is the Rochester pollen forecast updated?

Does pollen in Rochester 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 Rochester 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 Rochester, 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. |
