Local Environmental Conditions
The area around Outer Harbor is a mix of open grassland and bare ground, plus a good deal of built-up land. A stream or river nearby means riverside vegetation is part of the local pollen picture. Grass pollen is plentiful, while pigweed leads among the weeds. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

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