What to pack for Oaxaca in December
Heading to Oaxaca in December? Here's a packing list built directly from local climate averages — not generic blog advice.
December is mid-pack for warmth in Oaxaca (ranked 9 of 12) and among the driest (ranked 12 of 12). Day temperatures are flat compared to November and holding steady into January — so this month's packing list won't be identical to November's or January'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
- ★ T-shirts (5–6) — cotton or merino Avg high 25.4°C — warm
- • 1–2 long-sleeve linen or chambray shirts Cooler evenings + sun protection
Bottoms
- ★ Light chinos or trousers (1–2) Cooler evenings + cultural sites
- • Shorts (2) — knee-length Daytime warmth
Outerwear & layers
- ★ Mid-weight jacket — packable down (e.g. Uniqlo Ultra-Light Down) or trench Overnight lows 10.9°C — cool
- · Light scarf Versatile + comfort
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
- ★ 127V at 60Hz Mains electricity standard for Mexico
- ★ Plug types: A, B (Type A — flat 2-pin (US/Canada/Japan style)) Most common: A. Older buildings may also use B.
- • From the UK/Ireland: bring a G→A travel adapter UK Type G plugs don't fit Mexico's outlets
- • From continental Europe: bring a C/F→A travel adapter EU Type C/F plugs don't fit Mexico's outlets
- • If your device is labeled '220–240V only' (common for European hairdryers/kettles), it WILL underperform or not work at all here. Most phone/laptop chargers are dual-voltage — they're fine. Mexico runs 127V — too low for EU-only 230V devices
- · 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
