According to the Korea Meteorological Administration's 'three-month outlook for June-August 2026,' there is a 60 percent chance June will be warmer than usual, the government policy briefing service reported. Higher-than-normal sea-surface temperatures in the northern Indian Ocean and northern Pacific, which shape Korea's summer climate, are cited as the backdrop.

The agency expects Korea to be hotter than average this year, with heightened odds of heat waves and tropical nights, but not the record-rewriting extreme heat of 2024. It does foresee more localized downpours, with rain concentrated in specific areas rather than spread evenly nationwide.

As fears of extreme-heat and downpour damage grow, the government will reinforce its response. It is introducing a severe heat alert and a tropical-night advisory, and will send emergency disaster text messages for disaster-level rainfall, finely tiering the summer hazard response.

Heat is especially dangerous for outdoor workers and the elderly. Foreign laborers with heavy outdoor work, such as construction, delivery and logistics, and households short on cooling, face direct health threats. How fast and accurately the new alert system works on the ground will be key to safety this summer.
