What to pack for Chiang Mai in December
Heading to Chiang Mai in December? Here's a packing list built directly from local climate averages — not generic blog advice.
Chiang Mai, Thailand
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 28°C, hot dry — 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
Bottoms
- ★ Lightweight breathable shorts (3–4) — linen or quick-dry Avg high 28°C
- • 1 pair of light long pants Sun cover for long days + AC indoors
Outerwear & layers
- ★ Light jacket — denim, bomber, or packable windbreaker Overnight lows 16°C
Rain & weather protection
- · Travel-sized umbrella Just in case (low rain risk)
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
- ★ High-SPF sunscreen (SPF 30+ minimum, 50+ for fair skin) Strong sun expected
- ★ Sunglasses with UV400 protection Sunny conditions
- ★ Wide-brim sun hat or peaked cap Sun protection
Power, voltage & adapters
- ★ 220V at 50Hz Mains electricity standard for Thailand
- ★ Plug types: O, A, B, C (Type O — flat/round 3-pin (Thailand)) Most common: O. Older buildings may also use A, B, C.
- ★ 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. Thailand runs 220V — too high for US-only 110V devices
- • From the UK/Ireland: bring a G→O travel adapter UK Type G plugs don't fit Thailand'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
