Weather in Split in October

Croatia · 20-year averages, October

Prime time. October is about as good as Split gets. Highs average 20.9 °C, lows 15.2 °C, and rain falls on 10 days — nothing in the month is working against you.

October ranks 4 of 12 in Split: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain on 10 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: it never really gets hot: not one day in an average October reaches 30 °C; the day barely swings — 5.7 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 27.5 °C and the coldest night fell to 6.9 °C, and the wettest single day dropped 95 mm — roughly 108% of the month's rain in one day.

October is moderately variable: 15 mm in the driest year against 214 mm in the wettest, around an average of 88 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 11 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.

How October sits in the year

The month is on the way down: 4.4 °C cooler than September, with November dropping another 4.6 °C. The first week and the last are not the same trip.

Daylight in October

11.1 hours of daylight, losing 1.4 hours across the month. That is between Split's extremes of 15.4 and 9 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23.8 °C between the year's warmest afternoons and coldest nights.

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.

October in Split versus nearby

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

So: October is effectively as good as it gets here — 4 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
