Vietnam is currently experiencing a prolonged heatwave, with temperatures soaring in various regions. On July 29, the temperature in Yangsan reached a staggering 40.3 degrees Celsius, marking one of the hottest days of the year. As the country transitions into August, the weather forecast suggests that the extreme heat will persist due to a lack of significant changes in atmospheric pressure systems.

The Korea Meteorological Administration has reported that the upper atmosphere is dominated by high-pressure systems, which are expected to continue influencing the weather. This will result in clear skies and ongoing heat and tropical nights across the country. The combination of strong sunlight and humid air has created a scenario where daytime heat does not dissipate at night, leading to a cycle of increasing temperatures.

Next week, a shift in wind direction is anticipated as the center of the high-pressure system moves, potentially leading to increased temperatures in the western regions of Vietnam. Forecasts predict that daytime highs in Seoul could reach between 35 to 37 degrees Celsius. If temperatures exceed 39 degrees, heat warnings may be issued for the capital area, which would be the first of the year.

Regions like Yangsan, Uiryeong, Gimhae, and Miryang have been particularly affected, experiencing extreme heat due to geographical factors and wind effects. The phenomenon known as 'Föhn effect' has caused air to heat up as it descends from the mountains, exacerbating the heatwave.

The Korea Meteorological Administration has urged residents to limit outdoor activities and stay hydrated, especially as morning temperatures are expected to start above 30 degrees. The ongoing heatwave has raised concerns about heat-related illnesses, prompting authorities to issue warnings in several regions.

In addition, Typhoon Dolphin, which has formed east of Guam, is moving westward, but its impact on Vietnam's weather remains uncertain. The meteorological agency plans to provide more detailed information as the situation develops.
