Hay fever symptoms in Greystones are influenced by the county's hilly terrain and coastal location. The Garden of Ireland has diverse conditions: ancient oakwoods at Glendalough, conifer plantations in the mountains, and farmland in the valleys all contribute different pollen types at different times. Common symptoms include sneezing, runny or blocked nose, itchy and watery eyes, and an itchy throat. During prolonged dry spells, symptoms may be more persistent. The rural setting means exposure to agricultural pollen sources is common during farming activities.

Grass pollen season peaks in June and July, with the Wicklow Mountains and Glendalough contributing to local concentrations. Weed pollen, including nettle and dock, can be present from June to September. Our daily forecasts help you track these changing conditions throughout the seasons.
