In late spring, another pollen season comes. Many grasses release pollen during May and June. These tiny grains can spread far on warm, windy days. Fields, parks, and roadsides around Namur may all add grass pollen to the air during this time.

In summer, pollen from some weeds becomes more common. Plants like nettle, plantain, and mugwort can release pollen in July and August. This season is often less steady than spring. It can change with rain, heat, and dry weather in Namur.

In early autumn, a smaller pollen period may still happen. Mugwort can continue into September in some years. After that, cooler weather slows pollen release. By late autumn and winter, most trees and grasses have stopped, and pollen levels usually drop.
