Local Environmental Conditions
Nearby, within the neighborhood, the nearest creek or river hosts river oak, among the most allergenic wind-pollinated trees found on watercourses. Here, a short distance from here, a canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here. Local wind exposure and land use can shift the exact mix slightly from block to block.
The water-adjacent river oak is an early riser, starting well before the main spring rush, topping out around September. Woodland eucalypt and wattle pick up the pace next, through late winter into spring, peaking as wattle comes into full flower, generally August into September. By late spring, grass pollen is climbing steadily toward a November high point, and remaining a significant allergen right through summer until it eases in February.

How often is the Selwyn pollen forecast updated?

Does pollen in Selwyn 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 Selwyn 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 Selwyn, 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. |
