Local Environmental Conditions
This area, not far from here, has a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. Nearby, just around the area, a park whose turf grass and ornamental plane trees feed local pollen levels through spring. The general pattern described here holds fairly steady across nearby areas with similar land cover.
Eucalypt and wattle nearby take over the pollen calendar through late winter, cresting around August and September in the year's sharpest tree-pollen spike. Grass pollen counts rise through spring, reaching their peak around November, then holding at a high level well into January before easing off. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

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