Typhoon Dolphin May Intensify Heat Wave in Western South Korea

An intense heat wave is affecting western South Korea, with the approaching Typhoon Dolphin potentially worsening the extreme weather conditions [1, 2, 3].

This situation is critical because the interaction between the tropical storm and the existing heat dome could trap hot air over densely populated areas, including Seoul [1, 2].

Residents in the western region and areas east of the Taebaek Mountains are currently experiencing the brunt of the heat [1, 2]. Meteorologists said that easterly winds descending the western side of the Taebaek Mountains are bringing hot air into the region [1, 2, 3].

The timing of this event is particularly severe, as the heat wave established itself in late July 2026 [2, 3, 4]. Forecasts indicate that these extreme temperatures will persist into the following week [2, 3].

Weather analysts are monitoring Typhoon Dolphin closely to determine its exact impact on the peninsula. While typhoons often bring rain that can cool a region, this system may instead reinforce the high-pressure ridge driving the heat dome [1, 2, 3]. Such a reinforcement would effectively lock the hot air in place, preventing the natural relief typically associated with storm arrivals.

Local authorities continue to monitor the western provinces to manage the public health risks associated with prolonged heat exposure. The combination of high humidity, and extreme temperatures creates a dangerous environment for residents in the capital and surrounding provinces [1, 2].
