Local Environmental Conditions
This area, near this part of town, has river oak lines the bank, contributing some of the season's more persistent wind-borne pollen. Woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two, close to home here. As with most local readings, actual levels can vary somewhat with short-term weather swings.
The waterside river oak is consistently first to release pollen each year, climbing steadily from mid-winter into September. The woodland's eucalypt and wattle trees become the main pollen source as wattle flowers, peaking as wattle comes into full flower, generally August into September. Grass pollen becomes the dominant allergen through spring, peaking in November, then holding at a high level well into January before easing off.

How often is the St Ives pollen forecast updated?

Does pollen in St Ives 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 St Ives 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 St Ives, 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. |
