Local Environmental Conditions
River oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species; this sits near this part of town. Tree cover made up mostly of eucalypt and wattle, wattle in particular a well-known seasonal trigger; this sits close to home here. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
River oak by the water is typically first out of the gate, starting well before the main spring rush, topping out around September. Further into late winter, the area's eucalypt and wattle stands drive the pollen count, peaking as wattle comes into full flower, generally August into September. Grass pollen takes over next, building to a peak around November, holding through the summer months before tapering off by late February.

How often is the Marulan pollen forecast updated?

Does pollen in Marulan 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 Marulan 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 Marulan, 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. |
