Pollen count in Shannon today

Shannon usually follows the Clare forecast closely, but some days differ, so it has its own forecast. In 2026 it had 24 High or Very high days, against 22 in the Clare forecast.

Hay fever symptoms in Shannon are influenced by the county's varied terrain and coastal location. The unique limestone landscape of the Burren supports rare flora and extended flowering seasons. Hazel pollen can peak as early as February in this mild microclimate. Common symptoms include sneezing, runny or blocked nose, itchy and watery eyes, and an itchy throat. The frequent rainfall can provide some relief, though humid conditions may support mould spores. The rural setting means exposure to agricultural pollen sources is common during farming activities.

The milder Gulf Stream climate means tree pollen can appear as early as late January. In Shannon, the key local trees are hazel, ash, blackthorn, which affect spring pollen levels. Grass pollen season peaks in June and July, with the The Burren and Atlantic coast 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.

Strong Atlantic winds frequently clear the air along the coast and Cliffs of Moher, though the Burren can trap pollen in its sheltered valleys. 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. The regular rainfall in Shannon often provides natural relief by washing pollen from the air.

Yes, rain generally reduces airborne pollen levels in Shannon by washing particles from the air. The county's frequent rainfall means you'll often get natural pollen relief, though humidity can increase mould spore levels in areas like The Burren. 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.

The exposed Cliffs of Moher and coastal Loop Head offer naturally low-pollen environments. Avoid the sheltered Burren valleys on calm, warm days. 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 Shannon 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.
