Local Environmental Conditions
A stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months; this sits within the local area. Parkland with regularly mown grass and planted plane trees, both sources of seasonal pollen, not far from here. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
River oak along the water gets the season underway before other species, topping out well before most other trees start releasing pollen, around July and August. Grass pollen builds through spring and peaks in November, before staying elevated through the summer months into late January. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

How often is the Mount Moriac pollen forecast updated?

Does pollen in Mount Moriac 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 Mount Moriac 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 Mount Moriac, 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. |
