Local Environmental Conditions
A waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species; this sits close by. Here, a short distance from here, a park whose lawns and ornamental trees quietly add to grass and ragweed pollen levels. Local wind exposure and land use can shift the exact mix slightly from block to block.
Hazel and willow along the water get the season underway before other species, peaking in late winter through March. Grass pollen builds through late spring and peaks in June, before ragweed takes over as the dominant allergen from mid-August through October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

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