Local Environmental Conditions
As part of Friuli-Venezia Giulia, Gorizia lies on the Isonzo river plain at the Slovenian border and sees cypress and pine as its main tree pollen contributors; grass and coastal scrub pollen builds from the surrounding countryside as spring advances. The town's mix of open and built-up ground means exposure is rarely uniform across the area.
Gorizia follows a pattern typical of Friuli-Venezia Giulia: olive and plane first, then cypress and pine over the following weeks, then grass and coastal scrub pollen into early summer, running January through August overall. the dry Mediterranean summer that follows limits any late-season tail.

When is pollen season in Gorizia?
How often is the Gorizia pollen forecast updated?
The Gorizia pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Gorizia 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 Gorizia 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 Gorizia, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
