Local Environmental Conditions
The heart of Surabaya is densely built up. Close to the Mas River, riverside vegetation adds to local tree pollen. Locally, street trees, parks and lawns are the main sources in the built-up parts. Grasses along roadsides, verges and open ground also add to the overall pollen load. Pollen also travels on the wind, so vegetation in the wider surroundings adds to local levels as well.
With warm weather all year, between about 25°C and 30°C, pollen is present in most months rather than in one short season. The drier stretch around July to September usually brings the most pollen. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. Warm, damp weather from late spring into early winter also raises mold spore levels.

How often is the Surabaya pollen forecast updated?

Does pollen in Surabaya 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 Surabaya 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 Surabaya, 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. |
