Local Environmental Conditions
This area, close to home here, has the nearest creek or river hosts river oak, among the most allergenic wind-pollinated trees found on watercourses. Nearby, near this part of town, forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
River oak near the water opens the pollen calendar early, starting well before the main spring rush, topping out around September. Eucalypt and wattle in the woodland come next, as wattle bursts into flower, usually peaking from August into October. Spring brings rising grass pollen that crests in November, then holding at a high level well into January before easing off.

How often is the Dereel pollen forecast updated?

Does pollen in Dereel 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 Dereel 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 Dereel, 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 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. |
