Local Environmental Conditions
The WACA sits in suburban East Perth near the Swan River, its turf oval bordered by mature planted eucalypts and Moreton Bay figs typical of Perth's older sporting grounds, with river foreshore parkland nearby adding tuart and native riverine vegetation. Like much of the south-west and south, this area experiences a winter-spring wattle season followed by a grass-dominated pollen peak before summer's dry conditions take hold.
The WACA Ground's East Perth location near the Swan River places it squarely within Perth's Mediterranean pollen pattern: a mild, wet winter transitions into a dry spring, and as the cricket season warms up, so does the pollen count. Tree pollen from the ground's mature plantings and nearby eucalypts opens the season in August-September, with grass pollen from the surrounding parks and river flats peaking in October-November before summer's dry heat brings a swift decline.

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. |
