Local Environmental Conditions
The area around the heart of Alghero is mostly built-up land, with some open water. Common allergenic trees nearby include olive and oak. Beyond the trees, grasses matter a great deal, and mugwort and pigweed are the main weed sources. Around here, street trees, parks and lawns are the main sources in the built-up parts.
Tree pollen peaks in late spring, when the weather warms to around 20°C and olive and oak are in full flower. Grasses take over in late spring and keep pollen in the air into mid-fall. Mugwort and pigweed bring a final peak from midsummer into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen.

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