Pollen count in Dublin today

Hay fever symptoms in Dublin are influenced by the county's low-lying landscape and coastal location. Ireland's capital experiences an urban heat island effect that extends the growing season. Phoenix Park's 1,750 acres of grassland and trees create a significant pollen source. Street trees like London plane can trigger allergies. 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 urban environment means pollution can exacerbate symptoms, particularly in built-up areas.

Tree pollen season typically runs from February to May. In Dublin, the key local trees are plane, lime, oak, which affect spring pollen levels. Grass pollen season peaks in June and July, with the Phoenix Park and Dublin Bay 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.

Dublin Bay breezes provide relief along the coast, while inland areas can trap pollen during calm, warm days. The city is one of Ireland's driest areas. Sea breezes along the coast can help disperse pollen, making coastal areas preferable during high pollen days. Warm, dry, and windy days typically see higher pollen counts as conditions favour pollen release and dispersal. During dry spells, pollen levels can build up over several days.

Yes, rain generally reduces airborne pollen levels in Dublin by washing particles from the air. During the drier periods common in Dublin, rain showers provide welcome relief. However, thunderstorms can break pollen grains into smaller particles that penetrate deeper into the lungs. Light, steady rain is best for pollen relief. Check our daily forecast to plan activities around weather patterns.

Excellent pharmacy and specialist access throughout the city. Coastal walks in Howth, Dún Laoghaire, and Sandymount offer cleaner air. Avoid Phoenix Park during peak grass pollen in June. General tips include checking our daily pollen forecast before planning outdoor activities, staying indoors during peak pollen times (usually mid-morning and early evening), wearing wraparound sunglasses outdoors, and showering after being outside. The coastal areas of Dublin typically have lower pollen levels, especially when sea breezes are blowing. Consult your pharmacist or GP about antihistamines and other treatments tailored to your symptoms.
