Local Environmental Conditions
The riverbank shelters river oak, whose pollen spreads readily on the wind from spring onward, close to home here. This area, close to this spot, has parkland with regularly mown grass and planted plane trees, both sources of seasonal pollen. Seasonal timing here generally tracks the wider region, give or take a week or so.
Near the bank, river oak leads the seasonal calendar, peaking in mid-winter through September. Grass pollen climbs toward a November peak, with the season extending well into summer before finally winding down in February. Local weather swings can shift these windows slightly, but the overall order tends to hold. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

Does pollen in Oran Park 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 Oran Park 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 Oran Park, 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. |
