As record-breaking heat and monsoon rains sweep across South Korea this month, a growing number of consumers are opting to spend their leisure time indoors – fuelling a retail phenomenon known as “mallcations” and delivering a significant sales boost to department stores and outlet malls.

According to major retailers, foot traffic from July 1 to 17 rose sharply compared to the same period last year. Lotte Department Store reported a 10 per cent increase in visitors, while Shinsegae and Hyundai Department Store recorded respective gains of 14 per cent and 13 per cent, translating to sales growth of 11.1 per cent and 10.7 per cent. Hyundai Premium Outlet, equipped with underground parking, saw its sales surge 21.2 per cent.

The shift is largely attributed to the unpredictable weather, which has made air-conditioned indoor venues more appealing than outdoor spaces. Families in particular are driving a rise in food and beverage (F&B) sales: Lotte reported a 10 per cent jump, while Shinsegae and Hyundai logged 15.8 per cent and 12.4 per cent increases in F&B revenue.

With the summer vacation season approaching, seasonal product categories also experienced strong performance. Sales of swimwear at Lotte climbed 15 per cent, aided by a government tax incentive for cultural activities. Appliance sales rose 10 per cent under an energy efficiency rebate program.

Cooling bedding was another top seller, with Shinsegae reporting a 33.7 per cent spike in its bedding category. Hyundai saw 23.9 per cent growth in sportswear and 18.8 per cent in home living products.

Retailers are also rolling out immersive, summer-themed experiences to capitalise on the traffic. Lotte will launch a “Summer Gourmet Week” across all locations on July 25, offering sweepstakes for F&B customers. The chain will also host a “Summer Wine Festa”, discounted spirits promotions, and pop-up jewellery boutiques catering to seasonal accessory shoppers.

Shinsegae has introduced surfing gear pop-ups and is showcasing art exhibitions such as “Summer Hashtag #Summersnow” at its Daegu gallery, featuring over 100 artworks that capture the essence of summer.

Hyundai Department Store is transforming its spaces with a Hawaiian resort theme under the “Hu’i Hu’i Maui” campaign running through August 21. At The Hyundai Seoul, a fifth-floor indoor garden has been transformed into a tropical market, complete with pop-up stores selling musubi, straw hats, and hula outfits from 65 participating brands.

With Korea’s climate becoming increasingly unpredictable, retailers are embracing climate-proof leisure strategies – redefining malls not just as shopping centres, but as cool and curated summer destinations.
