Rome is the warmest of our European December cities, with sunnier days and double-digit highs. It's also the rainiest by total rainfall, which tends to arrive in heavier bursts on fewer days. You'll want a proper coat, but not the thermal layers you'd need in Vienna or Prague.
Romans dress for the season, not the thermometer, so expect wool coats, parkas and big scarves even on a bright day. Here's how to blend in from a 40 × 30 × 20 cm free bag.
The weather in Rome in December
Shoulder months for comparison

Source: WMO 1991–2020 climate normals, published by NOAA National Centers for Environmental Information (NCEI accession 0253808). Stations: Roma Ciampino (WMO 16239). Normals are long-term averages, not a forecast. Sunrise, sunset and daylight are calculated for the 15th of the month in 2026 (local time). °F and inches are converted from the metric figures. “n/a” means the station doesn’t report sunshine in this dataset.
- Cool days, cold nights. Average highs are in the low teens and lows are around 5 °C (measured at Ciampino, just outside the city).
- The highest December rainfall of our European guides (about 98 mm), but spread over only about 9 wet days, so it tends to pour when it rains.
- Much sunnier than Paris or London: roughly two and a half times the December sunshine hours of Paris.

Karen’s tipWeather changes fastLayer it up
Three thin layers from your capsule beat one thick coat in Rome in December: add or peel them off as the day changes.
- Base · next to skin
- Long-sleeve tee
- Mid · warmth
- Merino or cashmere crewneck
- Outer · wind and rain
- Wool coat, or a parka on rainy days
☀ When it warms up: Sunny December afternoons can feel mild: coat off or open, knit over your shoulders.
🎒 Stash it: The big scarf doubles as a cover-up for churches and a wrap in the evening.

Karen’s tip On the plane
- Wear your heaviest items on travel day: coat, knit and your bulkiest shoes. They’d take the most space and weight in your bag.
- Planes can be cold with the air con, so take a jacket on board.
- Pack a neutral wrap or pashmina too: it doubles as an evening wrap and a shoulder cover for churches here.
- An inflatable cushion that packs into its own small, discreet pouch: a head cushion on the flight and a pillow on beach sunbeds. You choose how much air goes in, so it’s as firm or soft as you like, which a foam neck pillow can’t do.

3 outfit formulas
Your style: best fits here are Parisian chic and Quiet luxury. Find your holiday style →
Earth-tone sightseer
- Camel or chocolate wool coat (or a parka on rainy days)
- Merino or cashmere crewneck
- Dark straight or wide-leg jeans
- Leather loafers or waterproof boots
- Oversized wool scarf
Tip: Olive, sienna and chocolate pieces all mix with each other, so a small capsule makes lots of outfits.
Vatican and churches
- Knee-covering midi skirt or trousers
- Long-sleeve top or fine knit
- Tights
- Comfortable flat boots
- The coat, plus a scarf to cover up
Tip: Plan this outfit for the day you visit St Peter's or the Vatican Museums so you're not turned away.
Aperitivo hour
- Silk-feel blouse or fine knit
- Tailored trousers or jeans
- Leather loafers
- Wool coat and scarf
Tip: Smart but relaxed: Rome isn't overly dressy, so loafers and a good coat are enough.
Swatches are a colour guide for each formula, not product photos.

Karen’s tipChange your hair, change the look
Swapping my hair from up in the day to down in the evening (or the other way round) gives the whole outfit a different look. Even one piece of jewellery I didn’t wear earlier does the same.
💡 It’s a free trick, and it saves packing extra outfits.

What’s underfoot
The ground
- Sampietrini: convex basalt setts laid on sand. Uneven, polished and slippery when wet
- Hills and steps (e.g. the Spanish Steps, Capitoline and Palatine)
- Gravel and uneven ancient paving at the Forum and Palatineeditorial
- Marble church and museum floors
Around 15,000–20,000 steps a day in the centre, most on sampietrini (pantheon.museum).editorial estimate
Trouble spots
- The sampietrini across the historic centre: heels wedge between them and they are slick in rain
- The approach to the Pantheon over basalt setts
- Roman Forum and Palatine: uneven ancient stone and graveleditorial
- Vatican and St Peter's: long standing and walking
☀ Day shoes
Broken-in trainers or walking shoes with a grippy rubber tread. Some guides suggest two pairs to alternate. Make them waterproof in December.
☾ Evening shoes
Smart flats or loafers with rubber soles, or low block-heel ankle boots.
✕ Leave at home
High heels and stilettos ('Leave your high heels at home', AUR). Smooth leather soles. New shoes.
Season notes: Late autumn and early winter is the wettest period. Wet sampietrini are properly slippery, so prioritise grip and waterproofing.
Karen’s tipHeels and cobbles don’t mix. Check the ground before you pack heels: thin heels catch between cobbles, so a wedge or block heel is steadier for evenings.
One pair, day to night: The best space-savers are a sleek waterproof leather ankle boot (Paris, London, Vienna & Prague, Amsterdam, Rome in December), a clean minimalist leather trainer or slip-on loafer (Tokyo, London), and a low block-heel sandal (cruise). Travel day: wear the heavier pair (see On the plane). Break in shoes before the trip.

The free baggage packing list
Your bag: 40 × 30 × 20 cm
Planned for 4 nights, using a soft backpack of about 20–24 litres made to the 40 × 30 × 20 cm size. The rule that makes it work: wear your bulkiest items on the plane. The dotted outline is easyJet’s bigger free bag.
Wear on the plane worn
In the bag 13 items
Karen’s tipRoll, don’t fold. I roll my clothes, stuff socks and small bits inside my shoes, and keep socks in a clear bag that comes home full of dirty laundry or wet swimming costumes. How I pack →
Karen’s tipPack a bag in a bag.A foldable shopping bag that folds into its own little pouch, for shopping, dirty laundry and pool towels. It saves buying a bag abroad.Why, and where to get one →
- Sandals
- Heavy thermals (a local says you won't need them)
- Shorts or anything above the knee for church visits
Liquids: going vs coming home
UK airports vary. Heathrow, Gatwick, Birmingham, Bristol, Edinburgh, Belfast International, Belfast City, Bournemouth, Southend allow containers up to 2 litres; most others, including Manchester, Stansted and Luton, are still 100 ml.
- 2 litresRome Fiumicino (FCO)to re-check
- 100 mlRome Ciampino (CIA), in a 1 L clear bagto re-check
Pack your liquids to 100 ml for the whole trip.
Karen’s tipWater bottle: keep it full through a 2-litre UK airport, or take it empty through a 100 ml one. Flying home: Rome Fiumicino: keep it; Rome Ciampino: empty it.Check your airport →
Karen’s tipDecant, don’t buy mini. I decant sun tan lotion into clear 100 ml spray bottles, and my day cream, night cream and cleanser into one squashy three-section silicone pot for trips of up to 4–5 days (separate pots if longer). Far cheaper than minis. How to do it →
Karen’s tip Check your room first
Read the hotel, Airbnb or hostel listing, or message the host, and ask whether they provide:
- Iron or steamer
- Hairdryer
- Toiletries: shampoo, shower gel (conditioner often isn’t supplied)
- Towels, plus beach or pool towels
- Washing machine or laundry service
- Plug adapters or USB sockets
- Kettle, tea and coffee
- Slippers and a robe
- A safe
Hostels often don’t provide towels or padlocks.
Karen’s tip Bring your own hair products. Most hotels supply shampoo but often not conditioner. Decant favourites into leak-proof travel bottles under 100 ml (fill them about ¾ full), or switch to solid bars, which don’t count as liquids. Amazon UK: Lericttor 100ml Silicone Travel Bottles ↗Check price · Amazon UK: Friendly Soap Travel Bar 95g (hair & body) ↗£4.72, price checked 20 Oct 2026 Every item they provide is one you don’t carry.
Karen’s tip No-iron packing
Pick fabrics that don’t crease. Woven cotton and linen crease; knits, merino, jersey and most polyester blends barely do.
- Hang creased clothes in the bathroom while you shower.
- Pack a small crease-release spray under 100 ml (it counts as a liquid).
- Roll clothes, and keep crease-prone pieces in a packing cube on top, not in a vacuum bag.
- Check whether your hotel or Airbnb has an iron.
Karen’s tip Buy it there?
Adding a checked bag typically costs around £60–80 return on a budget airline. So if your bag is full, buying bulky or liquid items when you arrive is often cheaper.
Think sun cream, full-size shampoo, insect repellent, a beach towel or flip-flops.
Usually yes in this destination: Italian supermarkets are generally around UK prices or a little below.
Tick items off as you pack (your ticks aren’t saved). Liquids rules depend on your departure airport and change from time to time. Check your airport’s current security rules before you decant your toiletries (see liquids rules by airport).
Flying there on Ryanair, easyJet or Wizz?
- Ryanair and Wizz Air give you a free 40 × 30 × 20 cm under-seat bag. Wearing the coat and boots leaves room for loafers.
- easyJet's free bag is 45 × 36 × 20 cm. Vueling basic fares match the 40 × 30 × 20 cm box.
- Rome's December is mild enough that a parka worn over one knit covers most days, which saves space.
Duty-free bag: Ryanair: extra bag allowed · easyJet: extra bag allowed · Wizz Air: extra bag allowed. It still has to fit under the seat or in a locker, and gate staff decide. Duty free and your free baggage →
Sizes come from each airline’s official page (see our free baggage reference for links). Rules change, so check your booking before you fly.
Baggage picks
The ticks compare each bag’s stated outer dimensions with each airline’s free-bag size. A struck-through name means the bag is too big for that airline. Soft bags squash a little; hard cases don’t. We haven’t tested these bags ourselves yet.
