Local Environmental Conditions
River oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species; this sits just outside the immediate area. Forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike, close to home here. Maintained parkland where turf grass and ornamental plane trees add to the local pollen mix, within easy reach.
Near the bank, river oak leads the seasonal calendar, reaching its high point sometime in late winter or early spring. Further into late winter, the area's eucalypt and wattle stands drive the pollen count, reaching maximum intensity across the August-September window. As spring turns to summer, grass pollen rises toward its November high, holding through the summer months before tapering off by late February.

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