Weather in Dublin in June
Ireland · 20-year averages, June
Shoulder season. June sits in between. You will get good days and you will lose some. You should expect rain on 15 days of the month, which is more days wet than dry.
June ranks 4 of 12 in Dublin: past the worst of the year but short of July, which is the month to book if the dates are open.
This is persistent light rain rather than storms: 15 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 16.4 °C days and 10.8 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: the day barely swings — 5.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 22 °C and the coldest night fell to 5.6 °C, and the wettest single day dropped 27 mm — roughly 36% of the month's rain in one day.
June is moderately variable: 22 mm in the driest year against 161 mm in the wettest, around an average of 76 mm. Roughly two Junes in three land near that average, and the third does something else entirely.
Wind is light at 12.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.
How June sits in the year
Temperatures hold steady either side: 13.8 °C in May, 16.4 here, 17.9 in July. Nothing about the timing within the month matters much.
Daylight in June
June is at or near the longest days of Dublin's year: 17 hours of daylight, gaining 0.4 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
Despite being inland, the year stays fairly even: 13.9 °C between the year's warmest afternoons and coldest nights.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
June in Dublin versus nearby
If Dublin is one option among several, the nearby comparison is worth making. Galway is close enough to be a coin toss — 2.2 °C warmer, 2 days more rain. Cork is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: June is effectively as good as it gets here — 3 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
