June Weather in Ireland: A Closer Look
Temperature
June marks the beginning of summer in Ireland, with average temperatures ranging from 9°C (48°F) to 18°C (64°F). Coastal areas, influenced by the Atlantic Ocean, tend to be milder, while inland regions may experience slightly warmer daytime temperatures.
The national mean temperature for June is 13.6°C (56°F). Shannon Airport is one of the warmest spots, with average highs of 18.3°C, while exposed Malin Head in Co. Donegal only averages 15.3°C.
Averages are only a guide, though. Met Éireann ranked June 2026 as the 4th warmest June since 1900, with a national average of 15.33°C and a top temperature of 32.2°C at Athenry, Co. Galway, on 25 June. It was also wetter than normal everywhere, with Belmullet in Co. Mayo getting 175% of its usual June rain.
Rainfall
Rainfall varies across Ireland in June. Eastern regions like Dublin receive about 64 mm (2.5 inches) over 10 days, making them relatively drier. In contrast, western areas such as Valentia in Co. Kerry experience higher rainfall, averaging 101 mm (4.0 inches) over 13 days during the month.
Those “days” are days with at least 1 mm of rain, so expect plenty of light showers on top. Nationally, June averages about 85 mm (3.3 inches), which makes it the driest of the three summer months; August is the wettest at around 103 mm. If you are heading for Kerry, Connemara or the west coast of Ireland, pack for a few wet days.
Wind Speed
June experiences gentle winds, with average speeds around 16 to 17 km/h (10 to 11 mph). Coastal regions, especially along the west, may experience slightly stronger gusts due to Atlantic weather systems.
Belmullet in Co. Mayo, one of the windier stations, averages about 21 km/h (13 mph) in June. Calm days are good news for boat trips, including the crossings covered in our guide to the best time to visit Skellig Michael.
Daylight Hours
Daylight extends significantly in June, with approximately 17 hours of light daily. The sun typically rises around 5:00 AM and sets near 10:00 PM, providing ample daylight for outdoor activities.
On the longest day, 21 June, Dublin gets 17 hours between sunrise (4:57 AM) and sunset (9:56 PM). The further north you go, the longer it lasts: Malin Head gets 17 hours 27 minutes, and twilight runs until after 11:00 PM. That extra light is handy for long hikes such as climbing Croagh Patrick.
Sunshine
June is one of the sunniest months in Ireland, averaging 173.5 hours of sunshine. Only May is sunnier, at 191.4 hours, and June comfortably beats July (152.2 hours). Cork Airport is among the sunniest stations, with about 6.1 hours of sun a day.

Is June a Good Time to Visit Ireland?
For most visitors, yes. June gives you the longest days of the year, the second highest sunshine total and less rain than July or August, while temperatures are only a degree or so below the July peak of 19.1°C.
The one thing to plan around is the June Bank Holiday weekend, when Irish families head off too and popular spots fill up. The June Bank Holiday 2027 falls on Monday 7 June. Golfers will find June one of the best months on the course too, as our Ireland golf weather guide shows.
What to Pack for Ireland in June
- A light waterproof jacket: showers are likely on most trips, even in a warm June.
- Layers: a light jumper or fleece for cool mornings, breezy coasts and evenings.
- Sun cream and sunglasses: the sun is high and the days are long, so it is easy to burn on a bright day.
- Comfortable walking shoes: ideally something that copes with wet grass and cobbles.
