Local Environmental Conditions
Located close to this spot, this area has a waterway lined with river oak, a wind-pollinated species and one of the more potent allergen sources along Australian creeks and rivers. A mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia; this sits in the surrounding area.
Near the bank, river oak leads the seasonal calendar, topping out well before most other trees start releasing pollen, around July and August. Eucalypt and wattle in the woods pick up where river oak leaves off, typically the year's sharpest tree-pollen spell, centered on wattle's flowering in August and September. Grass pollen becomes the dominant allergen through spring, peaking in November, then persisting at a reduced but still meaningful level into the new year.

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