Korea's Extreme 40°C Heatwave Drives 375% Surge in Off-Season Winter Clothes Sales and 65% Jump in Food Delivery

The Quick Take

• GS샵's off-season winter fashion sales hit 190 billion won during the heatwave period, up 375% from 40 billion won the prior year
• Food delivery app Baemin saw samgyetang (Korean chicken soup) orders surge 65.1% and bingsu (shaved ice) jump 33.8% as consumers avoided cooking in 40°C heat
• LF몰's off-season winter product search volume doubled year-on-year as high prices pushed consumers toward discounted counter-seasonal luxury items

South Korea's record heat wave, with temperatures reaching 40 degrees Celsius and extreme heat alerts issued across the country, has produced a paradoxical consumer spending phenomenon: winter clothing sales have exploded during summer as Korean consumers exploit counter-seasonal discounting to purchase premium outerwear — cashmere, goose-down, and wool coats — at prices 60-80% below winter retail. GS샵 reported 190 billion won in off-season winter fashion orders from May through July 19, a 375% increase from 40 billion won in the equivalent prior-year period, while LF몰's 'off-season sale' search volume doubled year-on-year.

The delivery economy is the other major beneficiary: Yogiyo reported a 3.5% weekly increase in total food orders during the peak heatwave period, with individual days recording up to 8% growth, as consumers avoided cooking over heat in already-sweltering homes. Baemin tracked the biggest demand shifts — samgyetang orders (the traditional Korean restorative chicken soup) up 65.1% versus the prior month, bingsu (shaved ice desserts) up 33.8%, and kongkuksu (cold soy milk noodles) up 24.4%. The data reflects Korea's well-established delivery app ecosystem converting extreme weather into measurable platform volume.

The retail sector read-through is that Korean consumers are behaving rationally under sustained cost-of-living pressure: using the window of counter-seasonal discounts to pre-purchase high-ticket items rather than paying full price in November. The macro variable to watch is whether this behavior persists into the autumn buying season — if consumers have pulled forward a significant volume of winter clothing purchases, September-October full-price fashion revenue could be weaker than seasonal patterns suggest, creating a timing headwind for Korean apparel retailers.
