Weather in Graz in October
Austria · 20-year averages, October
A good month. October works. It is not the peak, but nothing about it fights you. Highs average 16.2 °C, lows 6 °C, and rain falls on 9 days — nothing in the month is working against you.
October ranks 5 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 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.2 °C days and 6 °C nights; the spread matters more here than any single number.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest October day reached 26.5 °C and the coldest night fell to -7.8 °C, and the wettest single day dropped 28 mm — roughly 46% of the month's rain in one day.
October is moderately variable: 21 mm in the driest year against 126 mm in the wettest, around an average of 61 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.
Wind is light at 5.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.
How October sits in the year
The month is on the way down: 5.1 °C cooler than September, with November dropping another 6.5 °C. The first week and the last are not the same trip.
Daylight in October
11 hours of daylight, losing 1.6 hours across the month. That is between Graz's extremes of 15.9 and 8.5 hours, so days are long enough not to constrain the plan.
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
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.
October in Graz versus nearby
If Graz is one option among several, the nearby comparison is worth making. Villach is the weaker option in October — within a degree on temperature, 3 days more rain. Zagreb is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: October works, with September the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
