Weather in Bari in June
Italy · 20-year averages, June
Prime time. June is about as good as Bari gets. Highs average 29 °C, lows 19.8 °C, and rain falls on 6 days — nothing in the month is working against you.
June ranks 5 of 12 in Bari: past the worst of the year but short of May, which is the month to book if the dates are open.
Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29 °C days and 19.8 °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: 12 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 41 °C and the coldest night fell to 12.9 °C, and the wettest single day dropped 37 mm — roughly 106% of the month's rain in one day.
June is moderately variable: 2 mm in the driest year against 81 mm in the wettest, around an average of 35 mm. Roughly two Junes in three land near that average, and the third does something else entirely.
Wind is light at 10.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 62%.
How June sits in the year
The month is on the way up: 5.1 °C warmer than May, and July adds another 3.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in June
June is at or near the longest days of Bari's year: 15.1 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.
Sea temperature
The sea sits at about 22.3 °C in June — comfortable for a proper swim. The sea peaks at 25.9 °C in August and bottoms out at 13.8 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
June in Bari versus nearby
If Bari is one option among several, the nearby comparison is worth making. Dubrovnik is close enough to be a coin toss — 4 °C cooler, 1 day more rain. Positano is a better bet in June — 5.4 °C cooler, the same number of rain days.
So: June is effectively as good as it gets here — 6 points behind May, which is inside the margin where the weather stops being the deciding factor and price starts being it.
