Weather in Ioánnina in August

A good month. August is a solid month to be in Ioánnina. Highs average 32.7 °C, lows 20.6 °C, and rain falls on 4 days — nothing in the month is working against you.

August ranks 7 of 12 in Ioánnina: 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 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 32.7 °C days and 20.6 °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: 7 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest August day reached 41.9 °C and the coldest night fell to 12.9 °C, and the wettest single day dropped 71 mm — roughly 284% of the month's rain in one day.

This is the volatile part. August rainfall has ranged from 1 mm to 97 mm across the twenty years measured — a 96 mm spread around an average of 25 mm. The average is real but almost no individual August looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 6.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 47%.

How August sits in the year

Temperatures hold steady either side: 32.5 °C in July, 32.7 here, 26.7 in September. Nothing about the timing within the month matters much.

Daylight in August

13.8 hours of daylight, losing 1.1 hours across the month. That is between Ioánnina's extremes of 15 and 9.4 hours, so days are long enough not to constrain the plan.

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

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.

August in Ioánnina versus nearby

If Ioánnina is one option among several, the nearby comparison is worth making. Lárisa is the weaker option in August — 2.2 °C warmer, the same number of rain days. Pátra is the weaker option in August — 3.3 °C warmer, 1 day less rain.

So: August works, with May the better month by 18 points if the dates can move. If they cannot, nothing here should stop you booking.
