Local Environmental Conditions
A stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months; this sits just around the area. Located within the neighborhood's edge, this area has forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike. A park whose lawns and ornamental plane trees quietly add to local pollen levels; this sits close by.
River oak along the water gets the season underway before other species, starting well before the main spring rush, topping out around September. Eucalypt and wattle nearby take over the pollen calendar through late winter, building to its sharpest point across August and September. Grass pollen becomes the dominant allergen through spring, peaking in November, then holding at a high level well into January before easing off.

How often is the Thirlmere pollen forecast updated?

Does pollen in Thirlmere 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 Thirlmere 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 Thirlmere, 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. |
