According to the Southern Regional Hydrometeorological Centre, central and northern areas of the city will face peak heat between midday and 3 pm, with minimum relative humidity forecast at 35-40 per cent.
Over the next three to 10 days, temperatures are expected to intensify further, ranging from 35 to 37 degrees Celsius, with some areas experiencing even higher levels, extending the current hot spell.
The combination of high temperatures and low humidity increases the risk of fires and explosions in residential areas, as well as forest fires.
Health risks are also elevated, with prolonged exposure potentially leading to dehydration, exhaustion and heatstroke. Residents have been advised to limit outdoor activity during peak hours, stay hydrated and monitor their health closely.
City authorities have urged power providers to avoid outages during peak heat periods and at night, as rising electricity demand puts pressure on supply during the dry season.
The Ho Chi Minh City Power Corporation has been instructed to prepare contingency plans for possible shortages or system incidents, while prioritising electricity supply for essential services.
