Local Environmental Conditions
Vegetation patterns around Baja reflect its setting on the Danube river bank in southern Hungary: birch and hornbeam lead the tree pollen count, and grass and cereal pollen from the surrounding Bács-Kiskun countryside adds a further layer through the season. Local parks and street trees create pockets of higher exposure near the greener parts of town.
From an early hazel and alder start, Baja moves into a birch and hornbeam peak before grass and cereal pollen extends the season into early summer, with February through September covering the year's exposure in this part of Bács-Kiskun. the Pannonian basin's notorious ragweed season builds from August into October, among the heaviest in Europe, a pattern shaped in part by the town's position on the Danube river bank in southern Hungary.

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