Prague Weather in December: What the Market Evenings Feel Like

Dark early, cold fast

The sun sets around 4:00 PM through December, earliest around 12 December, and the day lasts only about 8 hours. The official December average at the Klementinum station in the Old Town is about 2.6°C (37°F), so once the market lights come on, the evening sits close to freezing.

Standing still in a crowded square, you feel it most in your fingers and toes. This is when a hot cup at a mulled wine stall stops being a cliché and becomes a strategy.

The squares fill after dark, and a guided walk such as the Prague Christmas Market Walking Tour: Old Town Square in the Evening keeps you moving, which is the simplest way to stay warm.

Averages and extremes

The Czech Hydrometeorological Institute (ČHMÚ) has kept daily records at Klementinum in the Old Town since 1775. Its 1991-2020 December average there is about 2.6°C (37°F). Single months swing widely around that figure: the warmest December on the record averaged 7.2°C (45°F), and the coldest averaged -9.7°C (15°F).

Treat the average as a guide to packing, not a forecast.

The white Christmas reality check

The official December average at Klementinum in the Old Town is about 2.6°C (37°F), so the month hovers just above freezing on average and snow is possible but never a safe bet.

The practical reading is this. You may see snow, you should pack for it, but do not plan your trip around a postcard snow globe. The market lights, not the snow, carry the atmosphere, and they take over from sunset around 4:00 PM.

Build the day around the dark

Sunset around 4:00 PM changes everything. Sightseeing that would fill an evening in summer must happen in the middle of the day. Use the middle of the day for castle views, riverbanks and any walking you want to do in daylight.

Then flip the schedule. Markets are at their best after dark anyway, so let sunset move you from sightseeing to stalls. With only about 8 hours of light, do not spend the middle of the day indoors.

If you want scenery without standing in the cold, the Prague Heated Glass Boat Cruise runs with a covered and heated main deck, and Prague Boats sail in any weather. Its Advent cruises sail on Advent Saturdays and Sundays from 15:30 to 16:30, which puts you on the water as the daylight goes.

Indoor warm-ups

A concert is the classic warm-up stop between market sessions. Jakub Jan Ryba's Czech Christmas Mass, the Rybovka, is the traditional Czech Christmas music, and the Hybernia Theatre stages it as a one-hour show with projections that include the Třebechovice Nativity scene.

The working kit

Warm clothes including hats, scarves and gloves are the baseline. Add thermal underwear for the evenings, a warm sweater, and layers you can shed indoors, since cafes and shops are well heated.

Shoes matter more than coats. Prague's historical area is filled with cobblestones that can be slippery in wet or icy weather, and market squares are crowded after dark. Sturdy shoes with real grip beat fashion boots in December.

A water resistant outer layer earns its place, and spare gloves and socks help when the cobbles are wet.

If you would rather taste your way through the cold than fight it, the Prague Christmas Food Tour covers the street food stalls, and home bakers should look at the Czech Christmas Cookie Baking Class Prague, since vanilla crescents and Linz cookies are the cookies Czechs bake through Advent.

Crowds against atmosphere

The Old Town Square and Wenceslas Square markets run 28 November to 6 January, listed daily 10:00 to 22:00, while the neighbourhood markets close on 24 December.

To beat the worst crushes, go to the big squares in the late afternoon before full dark, or choose the neighbourhood markets. The Peace Square market in Vinohrady, in front of St Ludmila's Church, is one of Prague's largest and sells ornaments, ceramic nativity scenes, wooden toys, wool products, jewellery and mulled wine. Havelské tržiště is the only surviving market in the historic centre, dating from 1232.

Getting between squares is easy in the cold, since you are not walking for the weather. PID single tickets cover 30 minutes, 90 minutes, 24 hours and 72 hours.

If you want more markets under the same winter sky, the Dresden Christmas Market Day Trip From Prague puts you on the Striezelmarkt, which runs 25 November to 24 December, daily 10:00 to 21:00, and closes at 14:00 on 24 December.

A cold-proof evening

Sightsee in the middle of the day while the light lasts. From about 3:30 PM, walk into Old Town as the daylight goes. Hit the stalls while they are still walkable, then warm up indoors with dinner or a concert. Fried carp with potato salad is the most popular Czech Christmas dinner.

For the coldest hours, go indoors on purpose. The Rudolfinum hosts a Christmas gala in the Dvořák Hall, and the Czech Christmas Carols Concert Prague at the Hybernia Theatre is another warm seat.

A guide makes the cold hours efficient. Options run from the 2 hour Prague Christmas Market Tour to the Private Prague Christmas Tour with a Personal Guide with hotel pickup.

Four things to watch

First, the cobblestones. The historical centre is paved with them and they turn slippery in wet or icy weather, especially in the packed market squares after dark. Watch your footing and wear grippy shoes.

Second, the darkness. With sunset around 4:00 PM, unlit side streets feel later than they are. Stick to lit main routes in the evening.

Third, the cold. December averages about 2.6°C (37°F) in the centre, so layer up and dry out between outings.

Fourth, the crowds. The big squares fill after dark, so book tours, concerts and dinner ahead rather than arriving at the square and hoping.
