Local Environmental Conditions
Here, a short distance from here, moisture-loving wattle and casuarina dominate the bank, both quick to release pollen on the wind. A wooded stretch of plane tree and eucalypt, with eucalypt responsible for some of the sharpest spring counts, within the neighborhood. A green space of mown lawn and planted trees, both feeding into local grass and plantain and weed counts, within the neighborhood.
In Swansea Heads, temperatures climbing to 17.5°C by September likely mark the start of the main pollen release, with humidity around 68% helping keep counts airborne. Warmer conditions by December (22.4°C, 72% humidity) sustain grass pollen through the season, before rainfall of 169mm in March and cooling toward 14.7°C in June bring the season to a close.

Does pollen in Lake Macquarie 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 Lake Macquarie 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 Lake Macquarie, 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. |
