In spring, grass pollen begins to rise. It usually starts in late April and grows through May and June. In and around Alnwick, grasses in fields, parks, and gardens add a lot of pollen to the air on warm, breezy days.

In summer, grass pollen can still be present, but it often eases later on. June and July are important months for many wild plants too. Nettles and some weeds release pollen then. Dry weather can help their pollen move farther.

In late summer and early autumn, weed pollen becomes more important. Plants like mugwort may release pollen in August and September. By October, pollen levels often fall. Cooler weather, shorter days, and more rain usually bring the pollen season to an end.
