Clear Skies & Early Summer Heat: Busan & Gyeongnam Weather Forecast with Scattered Showers in Inland Areas

Clear Skies and Early Summer Heat in Busan, but Inland Gyeongnam Faces Spotty Showers

Busan, South Korea — May 14, 2026 — Residents of Busan and much of Gyeongnam province can expect pleasant, mostly dry conditions today, but inland areas in the northwest may see brief afternoon showers, according to the latest weather forecast.

The Busan Meteorological Agency reports that while the coastal city and surrounding regions will remain dry, with temperatures hovering around 15–23°C, isolated areas in the northwestern inland of Gyeongnam could experience 5–10mm of rain in the late afternoon. The agency advises travelers and outdoor workers to stay updated on localized alerts.

Early Summer Heat Arrives as Rain Moves Out

Following recent heavy rainfall that affected parts of Busan and Gyeongnam, meteorologists indicate that perceived temperatures are rising, with some inland areas nearing 33–35°C—potentially triggering heat wave warnings. By May 20, Busan itself is expected to see daytime highs of 31°C, while nearby Ulsan may reach 32°C, according to the Busan Meteorological Agency.

The shift from rain to heat reflects broader seasonal trends, with the agency cautioning that strong winds and high humidity could persist in some regions.

Travel and Outdoor Precautions

With clear skies forecasted for most of Busan, residents and tourists are advised to take advantage of the dry weather for outdoor activities. However, those planning trips to stadiums, airports, or large venues should account for potential crowding, particularly if using expedited services like CLEAR+ or TSA PreCheck, which are available at select Korean airports.

For those traveling internationally, CLEAR’s identity verification system—now operational at multiple global airports—offers faster security screening, though its availability in South Korea remains limited to TSA PreCheck partnerships at participating hubs.
