Croatia Split Weather in December — Climate Guide
December in Split is moderate
December is moderate for Split.
December in Split is mild and quiet, lifted by Advent — the Christmas-market season that brings lights, music, and festive stalls to the old town and Riva. It averages 12°C/6°C with frequent rain.
Advent in Split is a genuine reason to visit in winter: the palace alleys and the waterfront fill with mulled-wine stalls, food huts, concerts, and decorations, and New Year's Eve brings celebrations to the Riva. Outside the festive zones, it's a calm, low-priced city for the palace, cathedral, and Marjan walks.

Split in December — Full Picture
December in Split is mild and quiet, lifted by Advent — the Christmas-market season that brings lights, music, and festive stalls to the old town and Riva. It averages 12°C/6°C with frequent rain.
Advent in Split is a genuine reason to visit in winter: the palace alleys and the waterfront fill with mulled-wine stalls, food huts, concerts, and decorations, and New Year's Eve brings celebrations to the Riva. Outside the festive zones, it's a calm, low-priced city for the palace, cathedral, and Marjan walks.
The sea is too cold to swim, island ferries run reduced schedules, and rain and the bura wind are common — this is a city-break month, not a coastal one. Prices tick up a little around the holidays and New Year but stay far below summer.
Pack a warm jacket, a sweater, an umbrella, and a windproof layer. For festive atmosphere, mild weather, and a crowd-free Roman city, December's Advent makes it the most appealing of the winter months.
What to Wear & What to Pack
Mild Mediterranean winter — around 12°C/6°C, wet. A warm jacket, sweater, and an umbrella; a windproof layer for the bura. It rarely freezes or snows in the city.
