Local Environmental Conditions
River oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species, a short distance from here. Nearby, within the local area, eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
Water-edge river oak is usually the first allergenic tree active here, peaking in mid-winter through September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen takes over next, building to a peak around November, and remaining a significant allergen right through summer until it eases in February.

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