Vietnam Faces Prolonged Extreme Heatwave

Vietnam is currently experiencing a severe heatwave, with temperatures soaring above 40 degrees Celsius in various regions, particularly in the central provinces. The National Centre for Hydro-Meteorological Forecasting reports that from April 6 to 8, temperatures reached 41.9 degrees Celsius in Tay Hieu Ward, Nghe An, and 41.3 degrees Celsius in Con Cuong Commune. The heatwave is attributed to a persistent low-pressure system combined with a strong foehn wind effect, which has exacerbated conditions across the country. Forecasts indicate that this extreme heat will persist, with temperatures expected to range from 36 to 39 degrees Celsius in the north-west and 35 to 37 degrees Celsius in the Central Highlands and southern regions through April 14.

As temperatures rise, public health risks increase, with forecasters categorizing the heat risk at level 1 across most regions and level 2 in central provinces, where temperatures exceed 37 degrees Celsius for consecutive days. Dr. Mai Van Khiem, director of the forecasting center, noted that prolonged exposure to extreme heat could lead to dehydration and heat exhaustion, particularly among vulnerable populations. The heatwave is also expected to significantly impact economic activities, with increased electricity demand anticipated due to rising temperatures.

The extreme heat has driven national electricity consumption to unprecedented levels, reaching 1.078 billion kWh on April 7, a 15.2 percent increase compared to the same period in 2025. The peak capacity of the national power system hit 51,691 MW, with the northern region alone accounting for 24,717 MW. The surge in demand is attributed to the intense heat, which has prompted the National System and Market Operation Company Limited to urge the public to conserve energy and promote the use of rooftop solar power, which has become a significant contributor to the electricity supply.

In cities like Da Nang, residents and workers are grappling with the oppressive heat. Street vendors, construction workers, and fishermen continue their daily routines despite the harsh conditions. Local authorities have warned that prolonged exposure to high temperatures can lead to serious health issues, urging workers to stay hydrated and take necessary breaks. The situation reflects a broader trend across Vietnam, where the heatwave is expected to intensify in the coming months, particularly from May onwards.

Officials have indicated that the heatwave is likely to continue, with temperatures expected to gradually ease after April 14. However, experts predict that 2026 will see more frequent and severe heat events than in previous years, raising concerns about public health and energy consumption. The government has emphasized the importance of energy efficiency and the development of renewable energy sources to mitigate the impacts of extreme heat.

While most sources agree on the severity of the heatwave and its impacts, discrepancies exist regarding specific temperature readings and the exact duration of the heatwave's effects. Further monitoring and reporting will be necessary to provide a clearer picture of the ongoing situation.
