The second pollen season is from mid-May to July. Grasses release pollen during this time. This is usually the worst time for people with pollen allergies. It's because many grasses grow in Reading's parks and fields.

Weeds like nettle and sorrel release pollen from late June to September. This is the third pollen season. It's a bit less intense than the grass pollen season. But it can still be a problem for some people.

The pollen seasons in Reading can affect people differently. Some people might feel symptoms during all three seasons. Others might only feel them during one or two seasons. Pollen counts can vary from year to year.
