Local Environmental Conditions
Orbost, in East Gippsland, sits amid tall wet eucalypt forest and river red gum flats along the Snowy River floodplain. Grazing pasture covers cleared valley land, and remnant messmate and blue gum forest cover surrounding hills. Wattle is abundant on forest margins in late winter. Being further east and drier than the high country towns, Orbost's pollen profile leans more heavily on eucalypt forest and pasture grass than on rainforest or alpine species.
Orbost, on the Snowy River in East Gippsland, sees eucalypt forest flowering from late August feeding into the region's tree pollen count, with grass pollen from the surrounding dairy and grazing flats peaking in November. The area's mix of tall wet forest and cleared river-flat farmland gives both tree and grass sources close proximity to town, and higher East Gippsland rainfall keeps the season a touch longer than drier Victorian districts.

How often is the Orbost pollen forecast updated?

Does pollen in Orbost 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 Orbost 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 Orbost, 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. |
