Local Environmental Conditions
Joondalup Resort's Quarry and Dunes courses are built through a former limestone quarry and coastal dune landscape in Perth's northern suburbs, where banksia woodland and heath vegetation have been retained and incorporated around the fairways. This gives the course a distinctive native bushland character compared with more traditional parkland-style layouts, reflecting the sandy, dune-formed ground typical of the northern Swan Coastal Plain.
Carved around a former limestone quarry and its dune country, Joondalup Resort's Quarry/Dune Course sits in Perth's northern suburbs, where the same August-to-November season applies: introduced and native tree species around the quarry rim shed pollen first, from August into September, before grasses colonising the dune slopes and fairway margins take over through October and November. Once summer's dry heat sets in, pollen output collapses quickly, giving this dramatic course a short, sharp allergy season.

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