Local Environmental Conditions
Katanning, a sheep and grain centre in WA's Great Southern wheatbelt, sits amid cleared farmland where wandoo woodland remnants persist on travelling stock routes and hill country. Canola and wheat crops dominate the cropping landscape, while sheep graze pasture paddocks between crop rotations. Wattle flowers on woodland margins in late winter. The mixed sheep-and-grain farming system gives Katanning both a strong spring canola pulse and a longer pasture-grass season than pure cropping districts.
Katanning, in WA's Great Southern wheatbelt, follows the Mediterranean pattern of a concentrated spring pollen season, roughly August to November. Wattle opens proceedings in August, and grass pollen from the surrounding sheep and cropping paddocks builds through September into an October peak. The region's reliably wetter winter than the eastern wheatbelt supports steadier pasture growth, and the hot, dry summer that follows brings a firm end to the season by December.

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