Local Environmental Conditions
Foster sits in South Gippsland's dairy country, where eucalypt forest, including messmate and mountain grey gum, covers the nearby hills and Wilsons Promontory hinterland, while cleared valley paddocks carry dairy pasture grasses. Coastal tea-tree occurs on the fringe toward the coast. Wattle flowers on forest margins in late winter. The combination of wet eucalypt forest and intensive dairy pasture gives Foster a fairly classic South Gippsland pollen profile, grass-dominant through spring and summer.
Foster, gateway to Wilsons Promontory in South Gippsland, has a temperate coastal-hinterland season shaped by the dairy country around it. Wattle and eucalypt flower from late August, with grass pollen from surrounding paddocks peaking in November. The higher rainfall of this part of Gippsland keeps pasture growing later into the season than drier parts of Victoria, sustaining grass pollen a little longer into early summer.

How often is the Foster pollen forecast updated?
The Foster pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Foster 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 Foster 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 Foster, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
