What to pack for Perth in May
Heading to Perth in May? Here's a packing list built directly from local climate averages — not generic blog advice.
May is mid-pack for warmth in Perth (ranked 8 of 12) and moderate for rainfall (ranked 5 of 12). Day temperatures are 3°C cooler than April and cooling toward 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
- ★ T-shirts (5–6) — cotton or merino Avg high 20.7°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 12°C
Rain & weather protection
- ★ Waterproof jacket or rain shell (e.g. Patagonia Torrentshell) 12 rain days expected
- ★ Compact travel umbrella For sudden showers
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
- ★ 230V at 50Hz Mains electricity standard for Australia
- ★ Plug types: I (Type I — angled flat 3-pin (Australia/NZ/China/Argentina)) Single common plug type
- ★ From the US/Canada: bring an A→I travel adapter US Type A/B plugs don't fit Australia'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. Australia runs 230V — too high for US-only 110V devices
- • From the UK/Ireland: bring a G→I travel adapter UK Type G plugs don't fit Australia's outlets
- • From continental Europe: bring a C/F→I travel adapter EU Type C/F plugs don't fit Australia'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
