Local Environmental Conditions
Located within the neighborhood, this area has a stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months. A nearby park's turf and plane trees layer additional pollen onto the seasonal grass count; this sits in the wider area. Small shifts in elevation or soil type can move these figures a little either way.
River oak along the water gets the season underway before other species, usually the first pollen source active, peaking sometime in July or August. As spring turns to summer, grass pollen rises toward its November high, then holding at a high level well into January before easing off. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

Does pollen in St Kilda West 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 St Kilda West 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 St Kilda West, 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. |
