Ireland Dublin Weather in June — Climate Guide
June in Dublin is very-high
June is very-high for Dublin.
June brings Dublin's longest, brightest days — around the solstice it stays light until past 22:00, with a lingering twilight after, ideal for long evening walks and packed beer gardens. It averages a comfortable 18°C/11°C.
The weather is at its best, though 'best' here means mild and pleasant rather than hot, and showers can still pass through — pack a light waterproof. The endless daylight is the real summer draw.

Dublin in June — Full Picture
June brings Dublin's longest, brightest days — around the solstice it stays light until past 22:00, with a lingering twilight after, ideal for long evening walks and packed beer gardens. It averages a comfortable 18°C/11°C.
The weather is at its best, though 'best' here means mild and pleasant rather than hot, and showers can still pass through — pack a light waterproof. The endless daylight is the real summer draw.
Bloomsday (June 16) is a Dublin highlight for the UNESCO City of Literature — costumed readings, walks, and events retracing James Joyce's Ulysses across the city. A wonderfully Dublin occasion.
This is peak season: crowds and hotel prices climb sharply (Dublin's room shortage bites hardest now), so book well ahead. Day trips shine in the long daylight, and the city's outdoor life is at its liveliest.
Note: it rarely gets truly warm, so bring layers and an evening sweater. Expect peak prices and crowds, and reserve attractions and tours early.
What to Wear & What to Pack
Early summer — mild and bright at around 18°C/11°C, with the year's longest days (~17h light, bright past 22:00). Light layers, a t-shirt with a sweater for evenings, and a light waterproof. Comfortable, rarely hot.
