Local Environmental Conditions
Yogyakarta's parks and green spaces tropical tree and grass make up most of the pollen here, present throughout the year in this equatorial setting. Only the wet season brings the area's Yogyakarta rainfall patterns into play as a reliable interruption.
In Yogyakarta, tropical tree and grass disperses continuously through the year with no distinct seasonal boundary, though the wet season from October to April regularly interrupts counts. Humidity tends to keep pollen close to the ground rather than dispersing it widely.

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