Local Environmental Conditions
Built-up land makes up around 35% of the area near the heart of Petoskey, with a good deal of woodland and some open water. Standing water nearby means lakeside trees such as poplar are part of the local pollen picture. The allergenic tree mix nearby includes birch, maple and poplar. Grass pollen adds noticeably to the overall load.
Tree pollen peaks in late spring, when the weather warms to around 10°C and birch, maple and poplar are in full flower. Grasses take over in midsummer, with temperatures around 20°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. Mold spores join in from midsummer into early fall, when damp, warm spells let them thrive.

How often is the Petoskey pollen forecast updated?
The Petoskey pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Petoskey 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 Petoskey 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 Petoskey, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
