Essentials for Seoul in June
Compact, sturdy umbrella
A reliable umbrella is essential for navigating the frequent and sometimes heavy rainfall of the monsoon season, keeping you dry during sudden downpours without taking up too much space.
Waterproof or water-resistant backpack cover
Protect your electronics, documents, and other valuables from unexpected rain showers while you're out and about exploring the city.
Lightweight rain jacket or poncho
Provides an extra layer of protection against the rain without adding bulk or overheating you in the warm, humid weather.
Moisture-wicking t-shirts and tops
These fabrics will help keep you feeling dry and comfortable by drawing sweat away from your skin in the high humidity.
Quick-drying shorts or skirts
Ideal for staying cool and comfortable, and they'll dry faster if you get caught in a sudden rain shower.
Comfortable, breathable walking sandals or sneakers
You'll be doing a lot of walking, so choose footwear that offers good support and ventilation to prevent discomfort in the heat and humidity.
Portable fan
A small, handheld fan can provide immediate relief from the heat and humidity when you're on the go.
Sunscreen (at least SPF 30)
Even on cloudy or rainy days, UV rays can be strong, so protect your skin from sun exposure during long daylight hours.
Insect repellent with DEET or picaridin
Mosquitoes can be prevalent in humid climates, especially during the summer months, so protect yourself from bites.
Reusable water bottle
Stay hydrated in the warm weather by refilling your bottle at water fountains or cafes, reducing plastic waste.
Pro tips
Embrace Public Transportation
Seoul's public transport system is excellent and air-conditioned. It's often the quickest and most comfortable way to get around, especially when it's raining or very humid.
Stay Hydrated!
The high humidity can make you feel dehydrated quickly. Carry your reusable water bottle and drink plenty of fluids throughout the day. Look for plenty of cafes and convenience stores to top up.
Waterproof Your Electronics
With the monsoon season, make sure your phone, camera, and other gadgets are protected. A waterproof case or a dry bag for your backpack can be a lifesaver.
Be Flexible with Outdoor Plans
While you'll have plenty of sunshine, rain can be unpredictable. Have a backup plan for indoor activities like museums, art galleries, or shopping malls, especially during the afternoon when rain is most likely.
