Local Environmental Conditions
In Sisak-Moslavina, Sisak lies where the Kupa and Sava rivers meet; local vegetation is dominated by plane and oak, and grass from the wider countryside pushes totals higher as spring turns to summer. Exposure differs meaningfully between the town centre and its greener edges, with the surrounding Sisak-Moslavina land contributing an additional, steadier layer of grass pollen through the warmer months.
plane and oak defines the core of Sisak's pollen season after an early hazel and alder start, with grass stretching exposure into summer across February to September. Mediterranean-influenced summers keep late-season pollen modest here. Sisak sits where the Kupa and Sava rivers meet, which shapes the tail end of the cycle.

When is pollen season in Sisak?
How often is the Sisak pollen forecast updated?

Does pollen in Sisak 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 Sisak 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 Sisak, 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. |
