Annual Overview

In Silves, Portugal, pollen seasons happen every year. There are three main pollen seasons. They are tree pollen, grass pollen, and weed pollen seasons.

Updated: 2/22/2026

Tree pollen season usually starts in January and ends in March. During this time, trees like olive, oak, and cypress release pollen into the air. This can make the air thick with tiny particles.

Grass pollen season is next. It starts in May and ends in July. Many types of grass grow in Silves, and they release pollen during this time. This can be a problem for people who like to play outside.

Weed pollen season is the last one. It starts in July and ends in September. Weeds like ragweed and nettle grow in Silves and release pollen. This can make the air filled with tiny particles again.
