Local Environmental Conditions
Chios's position on Chios island's eastern coast facing Turkey means olive and oak dominate the local tree pollen count, with late grass pollen from surrounding Vóreio Aigaío land adding to totals into early summer. The mix of built-up streets and nearby open ground creates uneven exposure across the town, and residents on the leafier fringes tend to notice higher counts than those nearer the centre.
The season in Chios opens with hazel and alder, climbs to a olive and oak peak, and winds down as late grass pollen fades; January through August captures the full cycle here. the Mediterranean climate's dry summer keeps autumn pollen minimal, reinforced by the town's setting on Chios island's eastern coast facing Turkey.

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