Late spring and early summer bring grass pollen. This often runs from May to July in Bideford. Grasses in fields, parks, and gardens release lots of pollen. Ryegrass and other common lawn grasses are important sources during this busy season.

Summer can still have pollen in the air, especially from weeds. From July to September, plants like nettle and mugwort release pollen. Some wild plants along roadsides and riverbanks also add to it. Warm, dry days can keep pollen floating longer.

In autumn and winter, pollen levels are usually much lower in Bideford. Most trees and grasses stop releasing much pollen. A few mild days may still bring small amounts from late weeds or some trees. But this is the quietest time of year.
