Local Environmental Conditions
Nowra's Shoalhaven setting combines dairy and grazing pasture along the river floodplain with eucalypt forest in the surrounding hinterland ranges, home to a significant local defence presence at the nearby naval air base. Wattle and native shrubs are common in reserves and along waterways, while coastal heath appears toward the nearby beaches. This mix of pastoral floodplain and forested hinterland shapes Nowra's broad pollen exposure through spring.
Nowra, on the Shoalhaven River in NSW's south coast hinterland, has a temperate pollen season moderated by its coastal proximity but still influenced by surrounding forested ranges. Eucalypt and wattle pollen build from August, with grasses across the region's dairy and grazing country peaking October to December. Coastal breezes help disperse pollen compared to inland areas, though spring storms rolling off the escarpment can still trigger the thunderstorm-asthma mechanism recognised across southeastern Australia.

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