What to pack for London in March
Heading to London in March? Here's a packing list built directly from local climate averages — not generic blog advice.
March is mid-pack for warmth in London (ranked 8 of 12) and moderate for rainfall (ranked 6 of 12). Day temperatures are 3°C warmer than February and still warming into April — so this month's packing list won't be identical to February's or April's.
Essentials
- ★ Passport + a photocopy stored separately Travel documents
- ★ Phone + charging cables (USB-C, Lightning as needed) Daily essentials
- • Refillable water bottle (1L) Reduces single-use plastic + saves money
- • Compact daypack (15–20L) For day trips, hands-free walking
- • Travel-size first-aid kit (band-aids, ibuprofen, antihistamines) Pharmacy access varies
Tops
- ★ Long-sleeve shirts (3) — flannel, oxford, or thin knit Avg high 12°C — mild
- • T-shirts (3) — cotton or merino For warmer afternoons
- • Light cardigan or pullover sweater Cool mornings/evenings
Bottoms
- ★ Jeans or chinos (2) Versatile for mild weather
- • 1 dressier pair (dark chinos or trousers) Restaurants/evenings — works for smart-casual settings
Outerwear & layers

- · Light scarf Versatile + comfort
Rain & weather protection
- • Light rain jacket OR compact umbrella (pick one) 9 rain days
- • Waterproof boots Possible snow days
Footwear
- ★ Insulated waterproof boots (Blundstone, Sorel, or hiking-grade) Cold + possibly wet conditions

Local style + dress code

Power, voltage & adapters
- ★ 230V at 50Hz Mains electricity standard for United Kingdom
- ★ Plug types: G (Type G — flat 3-pin (UK/Ireland/Hong Kong/Singapore/Malaysia)) Single common plug type
- ★ From the US/Canada: bring an A→G travel adapter US Type A/B plugs don't fit United Kingdom's outlets
- ★ Check device voltage labels: 'INPUT: 100–240V' is dual-voltage (most modern phones, laptops, chargers — safe). Single-voltage 110V devices (older hairdryers, curling irons) need a step-down converter, not just an adapter. United Kingdom runs 230V — too high for US-only 110V devices
- • From continental Europe: bring a C/F→G travel adapter EU Type C/F plugs don't fit United Kingdom's outlets
- · Easiest option: a universal travel adapter (e.g. Anker, Epicka) that handles A/B/C/E/F/G/I in one — covers ~95% of countries. If you travel to multiple regions
⚖️ Can you carry-on?
Maybe — possible with a packable down jacket, careful shoe choices (one warm + one walking), and wearing your bulkiest layer on the plane. Expect to use most of the carry-on volume.
23 suggested items total — 5 essentials, 7 clothing items, 2 pairs of shoes.
