Local Environmental Conditions
River oak lines the bank, contributing some of the season's more persistent wind-borne pollen; this sits within the neighborhood. A mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia; this sits just around the area. Ground-level conditions like local landscaping can nudge these figures slightly either way.
Around Fully Self-Contained Recreational Vehicle 24 Hour Rest Area, the woodland's eucalypt and wattle trees become the main pollen source as wattle flowers, climbing steadily through late winter to a peak in August or September. Grass pollen becomes the dominant allergen through spring, peaking in November, and remaining a significant allergen right through summer until it eases in 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.
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. |
