Weather in Thessaloníki in July

Greece · 20-year averages, July

A good month. July works. It is not the peak, but nothing about it fights you. Highs average 33 °C, lows 21.2 °C, and rain falls on 5 days — nothing in the month is working against you.

July ranks 9 of 12 in Thessaloníki: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 33 °C days and 21.2 °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 July day reached 43.2 °C and the coldest night fell to 14.5 °C, and the wettest single day dropped 42 mm — roughly 145% of the month's rain in one day.

July is moderately variable: 0 mm in the driest year against 72 mm in the wettest, around an average of 29 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 6.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 50%.

How July sits in the year

Temperatures hold steady either side: 29.6 °C in June, 33 here, 32.9 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Thessaloníki's year: 14.8 hours of daylight, losing 0.6 hours across the 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 — 31.7 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Thessaloníki versus nearby

If Thessaloníki is one option among several, the nearby comparison is worth making. Lárisa is the weaker option in July — 2.4 °C warmer, 1 day less rain. Volos is a better bet in July — 4.4 °C cooler, 1 day less rain.

So: July is a compromise. September is 22 points better and is what Thessaloníki is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
