Local Environmental Conditions
Irákleio's Minoan island setting and the Giofyros River corridor olive and carob are the leading tree pollen sources, with grass from surrounding Attikí farmland adding to counts over the spring weeks. The dry summer that follows sharply limits pollen for the months that follow.
Irákleio's pollen builds from olive and carob in winter to a grass peak in spring, then falls away sharply as the dry Mediterranean summer takes hold, spanning January through June. Surrounding scrubland and farmland both add to the spring peak.

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. |
