Local Environmental Conditions
Antigonish's harbour setting features red spruce, maple, and coastal vegetation as pollen sources at this university town in northeastern Nova Scotia known for its Highland Games.
Antigonish sits amid rolling farmland near the Northumberland Strait in eastern Nova Scotia, giving it a moderate, maritime-influenced pollen season, with mixed forest producing a fairly typical spring tree bloom, while surrounding farmland sustains a steady grass and ragweed presence through late summer, softened somewhat by the strait's cooling sea air.

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