November 28, 2026 – January 6, 2027 · Old Town Square and Wenceslas Square, Prague
The Czech Hydrometeorological Institute's Praha-Ruzyně December normals, the figures on this city's December guide and the heart of the season. The market opens on 28 November, a month our November guide puts at 9°C / 48°F and 4°C / 39°F, and runs into January, when our January guide gives 4°C / 39°F and −1°C / 30°F. Daylight is for 10 December.
Prague's markets, 28 November to 6 January: 3°C / 37°F days, −2°C / 28°F nights, and cobbles that glaze.
Layer for dry cold. The Czech Hydrometeorological Institute's Ruzyně figures give December 2.8°C by day and −2.2°C at night, a monthly mean of 0.4°C, with 25.7mm of precipitation across only about 6 days; Klementinum in the Old Town runs about two degrees warmer. So Prague sits at freezing rather than dropping through it at night, and it is rarely wet. That makes wool work: a loden coat, a chunky roll-neck over merino, and tweed, with no need for a waterproof shell. The one hazard is underfoot. Old Town setts polish to glass at a 0.4°C mean, and a cleated lug sole is the thing that keeps you upright between the stalls.
Prague in December is cold enough to freeze the square and dry enough that wool alone will do. Layer properly and the cold becomes the pleasant part.
There is no dress code at the Prague markets, and they are free to enter; you pay for svařák, trdelník and what you buy. The practical conventions are the ones for any dense crowd on stone: a bag worn in front with a zip, and shoes that grip. Prague's season is long. The markets on Old Town Square and Wenceslas Square run from 28 November to 6 January, eleven days past Vienna's Rathausplatz, and the first week of January is the quietest and cheapest stretch of the season. Plan the Castle and Petřín for the morning and the markets for after dark, when Old Town Square is at its best.

Loden is the Central European answer to dry cold: dense felted wool that blocks wind and sheds the occasional flurry, without a shell's rustle. On a month with only about 6 wet days it is all the outer layer you need. Forest green reads right against Old Town's baroque facades after dark.

Dry cold is where layering pays, and the base is the layer that does the most. Merino under the roll-neck holds warmth through an evening at −2°C / 28°F and does not overheat in a pub. Sage sits quietly under grey and green.

A roll-neck replaces the scarf, which is one less thing to hold with a svařák in your hand. Chunky rib traps air, which is the warmth in dry cold. Heather grey goes with green and tweed.

Tweed is warm, wind-resistant and fine in the rare flurry, and it keeps going to a concert at the Rudolfinum after the market. A pressed crease makes it evening wear. It takes a thermal legging underneath below zero.

Old Town setts are polished by centuries of feet, and at a 0.4°C mean they glaze. A deep cleated sole bites into them where a smooth sole slides. Felt lining keeps your feet warm through an hour at the stalls.

In dry cold a knit glove stays dry, and leather fingertips let you hold a hot svařák cup and tap a card without taking them off. Forest green matches the coat. Thin enough to handle coins at a trdelník stall.

Prague sits at freezing for much of the month, and a close merino beanie covers the ears without a bulky cuff under the coat's stand collar. Charcoal disappears into the rest of the look.

Old Town Square in December is one of the densest crowds in Europe. A zip-top crossbody worn in front keeps a phone and cards to hand and out of reach. Coated fabric wipes clean of a spilled svařák.
Sage merino · grey roll-neck · tweed trousers · black winter boots · loden coat open. Prague Castle and Petřín in the morning, before the square fills.
Loden coat buttoned · charcoal beanie · green gloves · crossbody in front. Old Town Square after dark, a svařák by the tree, the evening at −2°C / 28°F.
A suggested look — forest green loden coat, heather grey chunky roll-neck, grey-brown tweed trousers, black lace-up winter boots, charcoal merino beanie.
Layers of wool and a cleated sole. The Czech Hydrometeorological Institute gives December 3°C / 37°F by day and −2°C / 28°F at night with only about 6 wet days, so a merino base, a chunky knit and a wool or loden coat work without a waterproof shell. Old Town's setts glaze in the cold, so wear lined boots with a deep lug.
From 28 November 2026 to 6 January 2027 on Old Town Square and Wenceslas Square, according to Prague City Tourism. They are free to enter. The first week of January is the quietest part of the season.
Yes, and drier. The Czech Hydrometeorological Institute's Ruzyně figures give 2.8°C by day and −2.2°C at night with about 6 wet days; Vienna's Hohe Warte gives 4°C and −0.4°C with about 9. Prague sits at freezing for more of the month, but the dryness makes layering work better.
Often, in the Old Town. The setts are polished smooth, and with a December mean of 0.4°C they glaze after dark. A lug or cleated rubber sole is the single most useful thing you can pack.
