High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.
Eastern & Dublin (Leinster and East Coast)
July typically brings the warmest, driest weather on the east coast, with long evenings that make rooftop bars and seaside walks appealing; expect daytime highs usually in the mid-teens to low twenties on sunny spells. Tourist crowds peak - the city and coastal villages like Greystones are busy - but day trips to Glendalough before noon are still rewarding. Waterproofs can usually be left in a daypack, although sudden showers remain possible.
The Midlands & Shannon Basin (Central Plains)
July’s generally mild and pleasantly warm daytime temperatures encourage canoe trips on the Shannon and festivals in towns such as Roscommon and Tullamore. Afternoon showers occur but they rarely last long; evenings may be warm enough for outdoor dining in sheltered spots. For visitors, this is high season for small-town tourism - expect local events and limited room availability on bank holiday weekends.
Southwest (Cork, Kerry, Ring of Kerry, Dingle Peninsula)
July tends to be warmest and busiest in the southwest, with lively towns and full summer festivals such as the Puck Fair and local arts events. Midges and small biting insects can be present in boggy glens during calm, humid nights so carry repellent for evening walks. If you plan to visit Skellig Michael or the Blasket Islands, book early and keep a flexible schedule for boat weather.
West Coast & Connemara / Galway / Clare (Aran Islands, Cliffs of Moher)
July is typically the warmest month but by Irish standards remains mild, with frequent breeze off the Atlantic that moderates heat and keeps clouds moving. This is peak visitor season for Galway’s summer festivals and the west’s popular hikes; book accommodation early. Expect occasional heavy showers and carry a waterproof daypack - the weather can switch quickly between brilliant blue and blowing rain.
Northern & Northwest (Antrim Coast, Derry, Donegal)
July brings the warmest and often sunniest spells of the year to the north and northwest, with lively festivals in Derry and coastal villages hosting music and cultural events. Peak tourist numbers appear in popular spots like Portrush and Malin Head, and accommodation fills quickly on bank holidays. For island excursions and sea activities, book early and bring windproof layers for cooler sea breezes.
