South Korea Is Experiencing a Record-Breaking Heat Wave: How Locals Survive the Summer

 If you are planning to visit South Korea during peak summer, there is one crucial detail you need to prepare for: it is exceptionally hot. 🥵

South Korea has experienced historic heat, shattering long-standing weather records. On August 2, 2026, the city of Yangsan recorded 42.5°C (108.5°F)—the highest temperature measured in South Korea since modern meteorological observations began.

🌡️ Is South Korea Really This Hot?

South Korea is famous for its four distinct seasons. However, rapid climate shifts make spring and autumn feel fleeting, while summers grow longer, hotter, and more humid.

Metric	Temperature	Date / Context
New All-Time National Record	42.5°C (108.5°F)	August 2, 2026 (Yangsan)
Previous National Record	41.0°C (105.8°F)	August 1, 2018 (Hongcheon)

The extreme heat poses serious health risks, particularly for older adults and outdoor workers, with heat-related illness warnings issued nationwide throughout July and August.

🍲 How Koreans Beat the Heat: The Power of Iyeol-Chiyeol

In Korea, surviving the summer isn't just about cranking up the air conditioning—it’s also about culinary balance.

A core concept in Korean health culture is Iyeol-chiyeol (이열치열), which translates to "fighting heat with heat." The logic is that consuming hot, nutrient-dense foods helps replace lost fluids and nutrients while balancing internal body temperature with the sweltering outdoor climate.

The Sambok (삼복) Period

Koreans mark the hottest days of summer across three specific dates known as the Sambok (삼복) period:

• Chobok (초복): Beginning of the peak heat.

• Jungbok (중복): Middle peak heat.

• Malbok (말복): Final stretch of intense summer heat.

On these days, long lines form outside restaurants for Samgyetang (삼계탕)—a whole young chicken stuffed with glutinous rice, ginseng, garlic, and jujubes served bubbling hot in a stone bowl.

🎒 Summer Travel Packing Essentials

If you are traveling in Korea during July or August, do not underestimate the humidity and sun intensity. Pack these essential items to stay comfortable:

• ☂️ UV-Blocking Parasol / Umbrella: Widely used by locals of all ages to block direct sun.

• 🪭 Handheld Portable Fan: A must-have item for waiting outdoors or walking between subway exits.

• 🧊 Cooling Neck Ring / Neck Fan: Excellent for long sightseeing days.

• 🧴 Sunscreen & Reusable Water Bottle: Hydration and sun protection are vital.

• 👕 Light, Breathable Fabrics: Linen or moisture-wicking materials work best.

💡 Local Tip: Watch out for Naengbangbyeong (냉방병)

Naengbangbyeong refers to "air-conditioning sickness"—a common local term for experiencing headaches, fatigue, or mild chills after moving back and forth between sweltering outdoor heat and aggressively air-conditioned indoor spaces. Keep a light cardigan in your bag for long train rides or café stops!
