🎒 What to Pack for a Trip to Seoul in June

Packing for Seoul in June requires preparing for both sunshine and showers. The key is to choose lightweight, breathable clothing that can handle humidity.

Clothing Essentials:

• Lightweight fabrics: T-shirts, blouses, and shorts made from cotton or linen will keep you cool.
• A light jacket or cardigan: Essential for cooler evenings and for escaping the powerful air conditioning in malls and subways.
• Long trousers or skirts: Useful for evenings and for visiting palaces or temples that may suggest modest dress.
• Comfortable walking shoes: You’ll be doing a lot of walking, so pack trainers or comfortable sandals.

Weather Gear:

• Compact umbrella: An absolute must-have for sudden downpours, especially later in the month.
• Sunscreen SPF 50+: The sun can be strong, even on overcast days.
• Sunglasses and a hat: Protect yourself during sunny spells.

Travel Accessories:

• Reusable water bottle: Staying hydrated in the humidity is crucial.
• Portable fan: A small, handheld fan can provide welcome relief on humid afternoons.
• Power bank: To keep your devices charged while navigating the city.

Pro Packing Tips:

• Pack quick-drying clothes, as the high humidity can make it difficult for garments to air-dry.
• Many hotels provide umbrellas, but it’s always wise to carry a small, personal one.
• Bring a small, waterproof bag to protect your electronics from unexpected rain.
