Local Environmental Conditions
Most of the area around the center of Homeland is built-up land, with some scrubland and open grassland. A stream or river nearby means riverside vegetation is part of the local pollen picture. Grasses matter a great deal here, and pigweed is the main weed source. In the immediate area, street trees, parks and lawns are the main sources in the built-up parts.
Then come the grasses, strongest in late spring and fading by early fall. The season closes with pigweed from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

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