Local Environmental Conditions
The center of Narellan sits among a blend of open grassland and built-up land, plus some woodland. Among allergenic trees nearby, olive is the main source. Grasses also feature strongly, alongside pigweed and plantain among the weeds. Compared with most places, olive is especially widespread here, which makes it one of the key local allergens.
Olive leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in mid-spring and keep pollen in the air into late summer. Pigweed and plantain bring a final peak from early summer into early fall. The olive period in mid-spring is usually the most intense time of year here.

How often is the Narellan pollen forecast updated?

Does pollen in Narellan 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 Narellan 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 Narellan, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
