Local Environmental Conditions
Portsea Golf Club sits at the tip of the Mornington Peninsula near the entrance to Port Phillip Bay, its terrain covered in coastal heath, ti-tree and banksia typical of this exposed, sandy stretch of coastline. Close proximity to both the bay and Bass Strait exposes the course to wind from multiple directions, supporting a hardy, low-growing native landscape rather than tall trees across much of the property.
At the tip of the Mornington Peninsula, Portsea Golf Club is as exposed to Bass Strait weather as any course in the region, which means the ryegrass pollen that dominates October to December often arrives on a stiff sea breeze rather than still air. Wattle and eucalypt build earlier, from August, and the same broader spring pattern, the one behind Melbourne's 2016 thunderstorm asthma event, still shapes conditions this far from the city.

When is pollen season in Melbourne?
How often is the Melbourne pollen forecast updated?
The Melbourne pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Melbourne 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 Melbourne 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 Melbourne, 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. |
