Local Environmental Conditions
A stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months, just outside the immediate area. Woods composed largely of eucalypt with wattle at the margins, a combination tied to sharp late-winter pollen spikes, close to this spot. 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, building through the depths of winter into September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, cresting around August and September in the year's sharpest tree-pollen spike. Grass pollen climbs toward a November peak, before gradually tapering off through the peak of summer into February.

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