What to pack for Maui (Kahului) in January
Heading to Maui (Kahului) in January? Here's a packing list built directly from local climate averages — not generic blog advice.
January is one of the coldest months of the year in Maui (Kahului) (ranked 10 of 12) and among the driest (ranked 12 of 12). Day temperatures are flat compared to December and holding steady into February — so this month's packing list won't be identical to December's or February'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 22.5°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
- ★ Light jacket — denim, bomber, or packable windbreaker Overnight lows 16.5°C
Rain & weather protection
- ★ Full waterproof shell jacket (Gore-Tex or similar — NOT a 'water resistant' soft shell) 19 rain days, 84 mm
- ★ Compact umbrella (windproof, vented) Heavy rain — basic umbrellas invert in wind
- ★ Quick-dry pants (1 pair) Cotton/jeans become miserable when soaked
- • Waterproof phone pouch + dry-bags for electronics Heavy rain WILL find its way in
Footwear
- ★ Comfortable walking shoes (broken in) Mild weather, lots of walking
- • Lightweight sneakers (1 backup pair) Rotation prevents blisters
Accessories
- • Sunglasses Bright days expected
- • Sunscreen (SPF 30) Year-round basics
Power, voltage & adapters
- ★ 120V at 60Hz Mains electricity standard for United States
- ★ 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 United States's outlets
- • From continental Europe: bring a C/F→A travel adapter EU Type C/F plugs don't fit United States'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. United States runs 120V — 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
