Local Environmental Conditions
Suburban district on the shores of Lake Macquarie, where spotted gum and banksia woodland on sandy coastal soils border residential streets and shopping precincts. Lakeside reserves carry casuarina and paperbark in low-lying, damper sections. Spring spotted-gum and banksia flowering along the lake's bushland fringe combines with grass pollen from parks and sportsgrounds for a fairly typical NSW coastal-woodland pollen profile.
Charlestown's inland position within greater Newcastle, away from the direct coastal breeze, sees a fuller temperate pollen season than the beachside suburbs, wattle and eucalypt tree pollen peaking August-September, and grass pollen from the suburb's parks and sportsgrounds building to an October-December peak that can run a touch higher here than at the coast due to reduced sea breeze dilution. The shopping precinct's surrounding streets still see solid tree pollen counts from established plantings each spring.

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