Local Environmental Conditions
Dalkeith, on the Swan River in Perth's western suburbs, is characterised by large riverside properties with extensive established gardens, peppermint tree and tuart specimens common on the coastal limestone soils, alongside jacaranda and other flowering exotics. Remnant native woodland persists in occasional reserve pockets. Dalkeith's affluent, garden-dense character gives it one of the more layered, tree-heavy pollen profiles among Perth's river suburbs.
Dalkeith's riverside setting and mature gardens give it a strong local tree pollen presence from wattle and eucalypt flowering from August, with grass pollen from parks and foreshore reserves peaking September-October. The Swan River's proximity can add humidity on calm mornings, but Perth's Mediterranean summer still brings a sharp end to the season once the dry heat sets in from December. Established native gardens throughout the suburb's larger blocks add further tree pollen beyond the riverside reserves.

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. |
