Local Environmental Conditions
The heart of Riversdale sits in a varied landscape of built-up land, scrubland and open grassland. Grass pollen adds noticeably to the overall load. In the immediate area, scrubland contributes pollen from shrubs, grasses and herbs; street trees, parks and lawns are the main sources in the built-up parts. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

How often is the Riversdale pollen forecast updated?
The Riversdale pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Riversdale 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 Riversdale 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 Riversdale, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
