What to pack for Hanoi in May
Heading to Hanoi in May? Here's a packing list built directly from local climate averages — not generic blog advice.
May is one of the hottest months of the year in Hanoi (ranked 3 of 12) and moderate for rainfall (ranked 4 of 12). Day temperatures are 4°C warmer than April and still warming into June — so this month's packing list won't be identical to April's or June'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
- ★ Lightweight LINEN shirts (3) — short and long sleeve Avg high 32°C, humid — linen wicks sweat, breathes, dries fast
- ★ Breathable t-shirts (4–5) — linen-blend, bamboo, or merino Avoid pure cotton in this heat
- · Tank tops (2) Peak heat hours (NOT for religious sites)
Bottoms
- ★ Lightweight LONG pants or knee-length skirts/dresses (3) — linen, breathable 32°C but religious sites require knee cover
- • Shorts (1–2) — for hotel/beach only Save for non-cultural settings
Outerwear & layers
- · Light cover-up (linen overshirt or scarf) for AC indoors Malls, restaurants, transport are arctic
Rain & weather protection
- ★ Waterproof jacket or rain shell (e.g. Patagonia Torrentshell) 14 rain days expected
- ★ Compact travel umbrella For sudden showers
Footwear
- ★ Walking sandals with arch support (Teva, Chaco, Birkenstock) Warm weather comfort
- ★ Comfortable closed-toe walking shoes — sneakers Long sightseeing days, religious sites, traffic-dodging
Accessories
- ★ Insect repellent (DEET 25%+ or picaridin) Mosquitoes thrive in warm + wet weather
- • Sunglasses Bright days expected
- • Sunscreen (SPF 30) Year-round basics
Local style + dress code
- ★ Light scarf or sarong for shoulder/knee cover Required for mosques, temples, and major churches
Power, voltage & adapters
- ★ 220V at 50Hz Mains electricity standard for Vietnam
- ★ Plug types: A, C, F (Type A — flat 2-pin (US/Canada/Japan style)) Most common: A. Older buildings may also use C, F.
- ★ 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. Vietnam runs 220V — too high for US-only 110V devices
- • From the UK/Ireland: bring a G→A travel adapter UK Type G plugs don't fit Vietnam'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
