Local Environmental Conditions
In Lake of the Sandhills, nearby, close to home here, the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring. Here, within easy reach, oak and birch dominating the treeline, both heavy contributors to the spring pollen load. Small shifts in elevation or soil type can move these figures a little either way.
Around Lake of the Sandhills, near the bank, hazel and willow lead the seasonal calendar, usually the first pollen source active, peaking sometime in February or March. Once hazel fades, oak and birch in the woods carry the season forward, reaching maximum intensity across the April-May window. Grass pollen rises through late spring toward a June high point, and then ragweed picks up the slack, running from mid-August through October.

How often is the Lake of the Sandhills pollen forecast updated?

Does pollen in Lake of the Sandhills 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 Lake of the Sandhills 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 Lake of the Sandhills, 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. |
