Local Environmental Conditions
Here, close by, a stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months. A park combining lawn grass and plane trees, both contributors to pollen here through the warmer months, within the neighborhood. As with most local readings, actual levels can vary somewhat with short-term weather swings.
The water-adjacent river oak is an early riser, climbing steadily from mid-winter into September. As spring turns to summer, grass pollen rises toward its November high, then persisting at a reduced but still meaningful level into the new year. Warmer or wetter years can pull these peaks a week or two earlier or later.

When is pollen season in North Star?
How often is the North Star pollen forecast updated?
The North Star pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in North Star 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 North Star 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 North Star, 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. |
