Local Environmental Conditions
Located close to this spot, this area has river oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species. A park combining lawn grass and plane trees, both contributors to pollen here through the warmer months; this sits close to this spot. Ground-level conditions like local landscaping can nudge these figures slightly either way.
River oak near the water opens the pollen calendar early, climbing steadily from mid-winter into September. By late spring, grass pollen is climbing steadily toward a November high point, then persisting at a reduced but still meaningful level into the new year. Warmer or wetter years can pull these peaks a week or two earlier or later.

Does pollen in Bittern 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 Bittern 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 Bittern, 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. |
