In late spring, grass pollen becomes important. Many grasses around fields, parks, and roadsides release pollen. This season often lasts from May into July. Warm and dry weather can make more pollen spread in the air.

In summer, weeds add more pollen. Mugwort is one common plant in this time. Other wild plants and some late grasses also release pollen. This season is often strongest in July and August, when days are warm.

In early autumn, the pollen level usually drops. Some weeds can still release pollen for a while. By October, the main pollen season is mostly over in Hildesheim. Cooler weather and more rain help reduce pollen in the air.
