Italy's Pollen Seasons

In Italy, tree pollen appears in spring. Alder and birch release pollen in March and April. Olive pollen follows in May and June, extending the tree season into early summer. These months can bring allergy symptoms.

Grass pollen is the most common type across the year in Italy. Its main season runs from May through July, with pollen from grasses in May, June, and July. May is the busiest month for pollen overall.

Later in the year, weeds add pollen to the air. Mugwort and ragweed release pollen in August and September in Italy. Their season comes after the main grass months, so late summer and early autumn include weed pollen.
