South Korea continues to experience a persistent heat wave, with southern regions under heat warnings and scattered rain expected in the north [1, 2].
The lingering high temperatures and humidity during late August challenge public health and infrastructure, extending the summer heat beyond typical seasonal patterns.
Weather caster Won I-da of YTN said Seoul's overnight low temperature reached 24.8°C [1]. While this provided a brief respite from the most intense tropical nights, daytime heat remains significant. The forecast for Seoul predicts a high of 31°C [1], though the apparent temperature is expected to feel like 33°C [1].
Atmospheric conditions are creating a split in weather patterns across the peninsula. While the southern region remains under a heat warning, the central-northern region—including Seoul, the capital area, and Gangwon Province—is expected to see isolated showers [1, 2, 3].
Won said the expected rainfall amount in these central-northern areas will range from five to 30 mm [1]. These showers are described as sporadic rather than a widespread cooling system.
The heat continues to affect diverse geographies, from the southern provinces to the inland mountains of Jeju [1, 2]. High humidity levels are contributing to the elevated feel-like temperatures, keeping the heat index high even when actual thermometer readings are moderate.
Reports on the scale of the warnings vary slightly. While the broadcast focused on heat warnings for the southern region, some written reports suggest a more nationwide heat warning is in effect [1, 2].

The persistence of high temperatures into late August indicates a delay in the typical seasonal transition to autumn. The combination of heat warnings in the south and sporadic rain in the north suggests an unstable atmospheric environment, where humidity prevents significant cooling despite occasional precipitation.
