Weather in Ioánnina in June

Prime time. June is about as good as Ioánnina gets. Highs average 28.2 °C, lows 17.1 °C, and rain falls on 6 days — nothing in the month is working against you.

June ranks 2 of 12 in Ioánnina. Only May scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 28.2 °C days and 17.1 °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: 11 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 39.1 °C and the coldest night fell to 8.3 °C.

June is moderately variable: 4 mm in the driest year against 82 mm in the wettest, around an average of 28 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 6.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 57%.

How June sits in the year

The month is on the way up: 6 °C warmer than May, and July adds another 4.3 °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 Ioánnina's year: 15 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 30.3 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

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 Ioánnina versus nearby
