Local Environmental Conditions
Serra extends along the Espírito Santo northern coast above Vitória, where native Atlantic Forest remnants, eucalyptus, and restinga coastal scrub are the main pollen sources in this large industrial metropolitan municipality. The tropical climate supports year-round pollen production, while the wet summer months bring the most frequent rainfall interruptions and the coastal Atlantic proximity means onshore breezes can periodically disperse pollen throughout.
Expect the strongest pollen exposure in Serra during the dry season, when native Atlantic Forest remnants and eucalyptus pollen disperses most easily, while the wet season brings the regular relief of rainfall.

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