Local Environmental Conditions
This location in Whiting is surrounded mainly by built-up land, which covers around 68% of the nearby area, with some woodland. Lawns and planted trees in a nearby park add to local grass and tree pollen. The allergenic tree mix nearby includes oak, maple and poplar. Beyond the trees, grasses matter a great deal, and mugwort and plantain are the main weed sources.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak, maple and poplar are in full flower. Then come the grasses, strongest in early summer and fading by early fall. Later, mugwort and plantain keep weed pollen in the air from midsummer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.

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