Grass pollen season starts in May and ends in July. It's usually the worst time for people in Hull. Pollen counts are highest on warm, sunny days.
Weed pollen season is from July to September. Some weeds, like ragwort, release a lot of pollen. This can make it hard for people to enjoy the outdoors.
Hull's coastal location can affect pollen counts. Sea breezes can bring pollen from other areas. People in Hull should check pollen forecasts to plan their activities.
