Local Environmental Conditions
Here, some 700 meters to the edge of the area, water here is bordered by hazel and willow, both notable sources of wind-borne pollen. The tree cover here leans heavily on oak and birch, both key drivers of spring pollen, roughly 400-500 meters to the north or south of here.
Along the waterway, hazel and willow release pollen first, arriving ahead of the rest of the season, cresting around late winter. Once hazel fades, oak and birch in the woods carry the season forward, topping out in the April-to-May stretch. Moving into early summer, grass pollen climbs to its seasonal high in June, before ragweed takes over as the dominant allergen from mid-August through October.

How often is the University View pollen forecast updated?
The University View pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in University View 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 University View 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 University View, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
