Belgium is the latest country to issue a heat alert due to extreme temperatures as the heat is expected to intensify in the days ahead, Belgium’s Royal Meteorological Institute announced.
Starting on Wednesday, maximum temperatures will reach and exceed 35°C in most regions, and an orange alert will be in effect across almost the entire country.
The United Kingdom’s health authorities have also issued a “red heat health” alert for Wednesday and Thursday as June’s all-time record temperatures are forecast to be broken.
London is “cooking,” United Nations Secretary General António Guterres said on Tuesday at London Climate Action Week.

The Met Office is forecasting a high of 38°C in southern England. Temperatures reached 34.6°C on Tuesday in Wisley, south-west of London.
“Red warnings are reserved for the most severe events and we’re expecting severe and significant impacts from this heatwave, with health impacts likely for many, even beyond those who are normally more vulnerable to the heat,” said Mark Sidaway, deputy chief forecaster for the UK Met Office.
During extended periods of heat, the body’s ability to regulate its internal temperature and eliminate excess heat is compromised, increasing the risk of heat exhaustion and heatstroke.
