Weather in Bologna in October

Prime time. October is about as good as Bologna gets. Highs average 21.5 °C, lows 11.1 °C, and rain falls on 10 days — nothing in the month is working against you.

October ranks 3 of 12 in Bologna. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 10 days, 2 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: it never really gets hot: not one day in an average October reaches 30 °C. Across the twenty years measured, the hottest October day reached 31.2 °C and the coldest night fell to 1.6 °C, and the wettest single day dropped 39 mm — roughly 53% of the month's rain in one day.

October is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest October on record still delivered 110 mm against 22 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 74 mm average is a reasonable planning figure, not a promise.

Wind is light at 6.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How October sits in the year

The month is on the way down: 5.5 °C cooler than September, with November dropping another 6.6 °C. The first week and the last are not the same trip.

Daylight in October

11.1 hours of daylight, losing 1.5 hours across the month. That is between Bologna's extremes of 15.5 and 8.9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 32.3 °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. If the dates are flexible, June is the trade worth considering — 13 points weaker on weather, and materially quieter.

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

October in Bologna versus nearby

If Bologna is one option among several, the nearby comparison is worth making. Padua is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Genoa is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: October is effectively as good as it gets here — 2 points behind September, which is inside the margin where the weather stops being the deciding factor and price starts being it.
