Local Environmental Conditions
Secret Harbour Golf Links runs through coastal banksia woodland and dune heath south of Perth, its links-style fairways bordered by low native shrubland and tuart trees typical of this stretch of the Swan Coastal Plain near Mandurah. As is typical for the south-west and south, wattle flowering through winter gives way to a spring grass pollen peak that eases once the region's dry summer sets in.
Secret Harbour Golf Links' dune-side holes sit within Western Australia's compressed Mediterranean pollen season, concentrated roughly August to November before the long dry summer takes hold. Banksia and casuarina among the coastal dunes contribute tree pollen from late winter, while grass pollen from the course's turf and surrounding reserves peaks through spring. Ocean breezes off the links typically keep counts a little lower here than in suburbs set back from the coast, though warm easterly winds blowing off the drier inland can occasionally push pollen levels up across the fairways.

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