Local Environmental Conditions
For Lady's Slipper, along the damp banks, hazel and willow release some of the year's first tree pollen; this sits within the local area. Nearby, near this part of town, maintained parkland where turf grass and ornamental species add to the grass and ragweed mix. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
At Lady's Slipper, hazel and willow near the water open the pollen calendar early, reaching its high point sometime in late winter or early spring. As spring turns to summer, grass pollen rises toward its June high, with ragweed climbing to its own high point from mid-August through October. Small variations in local weather can nudge these windows a few days in either direction.

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