Local Environmental Conditions
Here, within easy reach, the nearest creek or river hosts river oak, among the most allergenic wind-pollinated trees found on watercourses. Woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower; this sits close by. Located close to this spot, this area has maintained parkland where turf grass and ornamental plane trees add to the local pollen mix.
For Cottesloe Golf Course, the bank's river oak kicks off the pollen season ahead of the rest, reaching its high point sometime in late winter or early spring. By late winter, eucalypt and wattle in the woods take over, generally peaking somewhere between August and October. Grass pollen rises through spring toward a November high point, then persisting at a reduced but still meaningful level into the new year.

Does pollen in Mount Claremont 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 Mount Claremont 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 Mount Claremont, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
