Local Environmental Conditions
Here, near this part of town, river oak crowds the water's edge here, a well-known contributor to local casuarina pollen counts. A canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here, in the wider area. Located a short distance from here, this area has mown grass and planted plane trees in a nearby park, adding to the seasonal pollen mix.
At Sandy Point Reserve, river oak along the water gets the season underway before other species, hitting its peak before most other trees flower, around July into September. As spring turns to summer, grass pollen rises toward its November high, with the season extending well into summer before finally winding down in February.

How often is the Hay pollen forecast updated?

Does pollen in Hay 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 Hay 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 Hay, 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. |
