Weather in Graz in July

A good month. July is a solid month to be in Graz. You should expect rain on 16 days of the month, which is more days wet than dry.

July ranks 7 of 12 in Graz: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain on 16 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: 9 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 38.4 °C and the coldest night fell to 7.7 °C, and the wettest single day dropped 46 mm — roughly 43% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 172 mm against 25 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 107 mm average is a reasonable planning figure, not a promise.

Wind is light at 5.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 64%.

How July sits in the year

Temperatures hold steady either side: 25.1 °C in June, 27.4 here, 26.7 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Graz's year: 15.6 hours of daylight, losing 0.8 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 — 31.3 °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.

July in Graz versus nearby

If Graz is one option among several, the nearby comparison is worth making. Villach is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Zagreb is close enough to be a coin toss — within a degree on temperature, 4 days less rain.

So: July works, with September the better month by 10 points if the dates can move. If they cannot, nothing here should stop you booking.
