İzmit has a humid subtropical climate. This means pollen seasons happen in spring and early summer. Trees, grasses, and weeds release pollen into the air.

Updated: 3/4/2026

February to May is the worst time for tree pollen. Oak, pine, and cypress trees produce a lot of pollen. It's carried by wind and makes people uncomfortable.

Grasses and weeds add to the problem in late spring. June and July are peak months for grass pollen. Weeds like ragweed also produce a lot of pollen.

Pollen counts usually go down in August. But some plants like weeds and grasses still produce pollen. The weather affects how much pollen is in the air.
