Local Environmental Conditions
Here, near this part of town, a waterway lined with river oak, a wind-pollinated species and one of the more potent allergen sources along Australian creeks and rivers. Nearby, within easy reach, woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two. Nearby, close by, a park whose lawns and ornamental plane trees quietly add to local pollen levels.
Near the bank, river oak leads the seasonal calendar, usually peaking sometime between July and September. Eucalypt and wattle in the woodland come next, as wattle bursts into flower, usually hitting its highest point sometime between mid-August and mid-September. As spring turns to summer, grass pollen rises toward its November high, before continuing at a lower but still notable level through January and February.

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