Busan Weather Alert: Partly Cloudy Skies with Highs of 28°C and Heavy Rain Expected

Current Weather Conditions in Busan
Busan is experiencing partly cloudy weather conditions as forecasted by the Busan Meteorological Administration. The city is seeing intermittent cloud cover with temperatures reaching a maximum of 28°C during the day and an expected minimum of 23°C on the morning of June 28th. This weather pattern is typical for late June in the coastal city, where maritime influences create variable cloud conditions.
The current atmospheric conditions show the influence of warm, humid air masses moving in from the southwest, which is characteristic of the summer season in the Bu-Ul-Gyeong region. Weather monitoring stations across Busan have recorded consistent temperature readings, with the central observation point in Jung-gu Daecheong-dong serving as the primary reference for official weather data.
Residents and visitors should note that while the skies appear partly cloudy, the underlying weather systems suggest more significant changes ahead, particularly regarding precipitation patterns expected in the coming days.
Heat Warning and Health Precautions

The Busan Meteorological Administration has issued important health advisories as the maximum perceived temperature is expected to rise above 31°C. This elevated heat index poses significant risks for heat-related illnesses, prompting authorities to recommend limiting outdoor activities and exercise during peak daylight hours.
Health officials emphasize the importance of staying hydrated and seeking air-conditioned environments during the hottest parts of the day. The combination of high temperatures and humidity levels creates conditions where the human body's natural cooling mechanisms become less effective, increasing the risk of heat exhaustion and heat stroke.
Food safety has become another critical concern during this hot weather period. The Busan health authorities strongly advise thorough food management practices to prevent food poisoning, as bacteria multiply rapidly in warm conditions. Residents are urged to refrigerate perishable items promptly and avoid leaving prepared foods at room temperature for extended periods.
Expected Rainfall and Precipitation Patterns
Significant rainfall is forecast for June 28th, with precipitation amounts ranging from 5mm to 50mm expected between morning and afternoon hours. This wide range reflects the unpredictable nature of summer weather systems in the region, where localized heavy downpours can occur alongside lighter, more widespread rainfall.
Historical weather data shows that Busan experienced record-breaking rainfall earlier in June 2025, with the city recording its highest hourly precipitation rate for June since modern meteorological observations began in 1904. On June 14th, Busan recorded 61.2mm of rain in a single hour, surpassing the previous record of 50.1mm set in 1971.
The upcoming rainfall is part of a broader weather pattern affecting the Korean Peninsula, where atmospheric instability and low-pressure systems are creating conditions favorable for heavy precipitation. Weather models suggest that while the rain will provide some relief from the heat, it may also create additional challenges for transportation and outdoor activities.
Tidal Effects and Coastal Safety Concerns
A particularly important aspect of the current weather situation involves the strong lunar gravitational pull affecting tidal patterns through June 28th. During this period, sea levels will be significantly higher than normal, with the most pronounced effects occurring during high tide periods.
Coastal communities and low-lying areas near the shoreline face increased risks of flooding, especially when the predicted rainfall coincides with peak high tide times. The Busan Meteorological Administration has specifically warned about potential inundation of coastal lowlands and emphasized the need for enhanced safety measures around waterfront areas.
Water recreation activities require extra caution during this period, as higher sea levels combined with potentially rough weather conditions create dangerous situations for swimmers, surfers, and boaters. Local authorities are monitoring beach conditions closely and may implement temporary restrictions on water activities if conditions deteriorate further.
Community Response and Preparedness Measures
Local communities across Busan are taking proactive steps to prepare for the challenging weather conditions. Social media platforms and community forums show residents sharing tips for staying cool during the heat wave and preparing for the expected rainfall.
Many residents are stocking up on emergency supplies, including bottled water, non-perishable foods, and battery-powered devices in case of power outages during heavy rain periods. Local businesses, particularly those in the hospitality and tourism sectors, are adjusting their operations to accommodate weather-related changes in customer patterns.
Public transportation authorities are also preparing contingency plans for potential service disruptions during heavy rainfall periods. The city's drainage systems are being inspected and cleared to handle the expected precipitation volume, though concerns remain about the capacity to manage extreme rainfall events similar to those experienced earlier in June.
Long-term Weather Outlook and Climate Patterns
The current weather conditions in Busan reflect broader climate patterns affecting the Korean Peninsula during the summer months. Meteorological experts note that the region is experiencing above-average temperatures and more intense precipitation events, consistent with regional climate trends observed over recent years.
The Korea Meteorological Administration has indicated that the Bu-Ul-Gyeong region, including Busan, will continue to experience above-normal temperatures through July due to persistent hot and humid southwest wind patterns. This extended period of elevated temperatures is expected to be accompanied by periodic heavy rainfall events.
Climate monitoring systems are tracking these patterns as part of ongoing research into changing weather dynamics in East Asia. The combination of urban heat island effects in Busan's metropolitan areas and broader regional climate influences creates a complex weather environment that requires continuous monitoring and adaptive response strategies from both authorities and residents.
