Local Environmental Conditions
San Severo's tree pollen is dominated by plane and olive, a pattern typical of Puglia and reinforced by its position on the Tavoliere delle Puglie wheat plain; grass pollen adds further exposure from nearby farmland through the warmer months. Parks and leafier streets tend to register higher counts than the built-up core.
From an early cypress and olive start, San Severo moves into a plane and olive peak before grass pollen extends the season into early summer, with the winter-to-summer stretch from January to August covering the year's exposure in this part of Puglia. the dry Mediterranean summer that follows limits any late-season tail, a pattern shaped in part by the town's position on the Tavoliere delle Puglie wheat plain.

How often is the San Severo pollen forecast updated?

Does pollen in San Severo 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 San Severo 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 San Severo, 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. |
