Experts warn dangerous UV levels in Vietnam amid extended heatwaves

Hot temperatures start to build this week for much of Vietnam with levels of ultraviolet (UV) radiation forecast to reach “dangerous” levels, Vietnam News reported on Tuesday.

Levels of UV radiation in major cities across the country are expected to peak between 8 and 10 on a scale that according to experts, level 10.5 and above is regarded as “extreme”, said the National Centre for Hydro-Meteorological Forecast.

People are advised to wear loose-fitting clothing, drink water to stay hydrated, schedule outdoor activities carefully, and find shade when UV rays are strongest, between 11:00 a.m. and 3:00 p.m., the national weather center said in a statement.

According to the World Health Organization, a UV index of 7.5 to 10.4 is deemed “very high”, and just 15 minutes of unprotected exposure could burn human skin and eyes.

The national weather center also said the heat is expected to advance until the end of May in the northern and central parts of the country which could see average temperatures rising by about 0.5-1 degrees Celsius from last year’s figures. ■
