Essential Tips

What to Pack

Quick-dry synthetic shirts and moisture-wicking underwear - 70% humidity means cotton stays damp for hours

Compact umbrella with UV protection - doubles as sun shade and rain protection for unpredictable afternoon storms

SPF 50+ sunscreen - UV index of 8 causes burns in 15 minutes, reapply every 2 hours

Lightweight breathable pants - shorts aren't suitable for temple visits or traditional restaurants

Portable fan or cooling towel - essential for outdoor activities when temperatures feel like 35°C (95°F)

Waterproof phone case - sudden thunderstorms can damage electronics within seconds

Comfortable walking shoes with good grip - wet pavement becomes extremely slippery during storms

Electrolyte packets or sports drinks - high humidity increases dehydration risk significantly

Light cardigan for over-air-conditioned indoor spaces - temperature differences of 15°C (27°F) between inside/outside

Insect repellent containing DEET - increased mosquito activity near rivers and parks during humid season

Insider Knowledge

Schedule indoor activities between 11am-4pm when outdoor temperatures feel like 35°C (95°F) - locals retreat to department stores, museums, and underground shopping areas during these hours

Download KakaoMap app with Korean keyboard enabled - essential for navigating Daejeon's limited English signage and calling taxis during sudden storms

Book accommodations near subway stations (Government Complex or Yuseong) - August heat makes short walking distances crucial and subway provides reliable transport during thunderstorms

Carry ₩1,000 coins for public restrooms and locker rentals - many tourist areas charge fees and card payments aren't always accepted for small amounts

Avoid These Mistakes

Planning full-day outdoor itineraries without accounting for afternoon thunderstorms - always have 2-3 hour indoor backup plans ready

Underestimating walking times in heat and humidity - distances that take 10 minutes in cool weather require 20+ minutes with rest breaks in August

Wearing dark colors that absorb heat - locals wear light colors and long sleeves for sun protection, not shorts and tank tops like many tourists
