Local Environmental Conditions
Surabaya spreads across the East Java coastal lowlands at the Mas River estuary, where introduced urban trees, tropical grasses, and roadside vegetation introduced urban trees and roadside vegetation dominate locally and disperse continuously through the year. Rainfall during the wet season provides the most frequent breaks in an otherwise steady pollen presence.
Surabaya sees no real off-season for introduced urban trees and roadside vegetation pollen given its equatorial position, though rain during October to April interrupts counts more often than the remainder of the year. Urban green space and roadside vegetation both contribute steadily through the year.

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 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. |
