Local Environmental Conditions
Around Garden Park, nearby, close to home here, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. Local wind exposure and land use can shift the exact mix slightly from block to block. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
For Garden Park, hazel and willow near the water open the pollen calendar early, usually the first pollen source active, peaking sometime in February or March. Grass pollen takes over next, building to a peak around June, and then ragweed picks up the slack, running from mid-August through October. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

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