Local Environmental Conditions
Nearby, not far from here, river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. This area, within the local area, has a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. Nearby, in the surrounding area, a park whose lawns and ornamental plane trees quietly add to local pollen levels.
The water-adjacent river oak is an early riser, peaking in mid-winter through September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, typically the year's sharpest tree-pollen spell, centered on wattle's flowering in August and September. As spring turns to summer, grass pollen rises toward its November high, before continuing at a lower but still notable level through January and February.

Does pollen in Sherbrooke 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 Sherbrooke 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 Sherbrooke, 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. |
