How to explain such heat in Belgium?
The explanation for this crushing heat is a cold drop off the Iberian Peninsula. It acts as a heat pump. She brings this burning air up from North Africa. We are not the only ones affected. These high temperatures have already affected Spain with extreme values. 43 degrees have been recorded in the southern part of the country in recent days. Our closest neighbors are also affected. In France, 40.2° were recorded in Argeliers in the Aude department, this Thursday, June 16. The earliest 40 degrees ever recorded in mainland France.
With us, the night from Friday to Saturday will be tropical. The mercury will not drop below 16 to 18°. No wind, nothing to stir up the atmosphere. The atmosphere will be heavy there.
Saturday: extreme heat
The program for this Saturday? Burning sun from morning until evening. As expected, we are going to experience the peak of these heats. A mercury that panics throughout the country. In the big cities, we expect: 32°C in Saint-Hubert, 33°C in Spa, Gedinne and Charleroi, 35°C in Liège, Namur, Mons, Brussels, Ghent and 36°C in Hasselt. Temperatures in Brussels will be the same as in Algiers this Saturday. An exceptional situation that will have to be monitored with, perhaps, weather records broken this Saturday afternoon. Also pay attention to air quality. It will be very mediocre according to the Interregional Environment Unit (Celine). It predicts high ozone concentrations and a risk of local exceedances of the European information threshold. We expect this Saturday between 160 and 190 micrograms / m3. During high concentrations, as a preventive measure, people who are particularly sensitive to air pollution (children, the elderly, people with respiratory problems, etc.) should avoid unusual physical exertion and any outdoor exercise between 12 p.m. and 10 p.m.
