Record Heat Threatens Southern Europe
Southern Europe is experiencing a heat wave with Sardinia recording 47.8°C, close to the European record of 48.8°C set in 2021; temperatures could reach near 47°C in parts of Spain this week. [4] The current record is nearly 49 degrees. [4] Statsmeteorolog Unni Nilssen confirms a heat wave in southern Europe. [4] Sardinia registered 47.8 degrees, near the European record of 48.8 degrees set on Sicily on 11 August 2021. [4] Spain will be particularly affected, though the record will probably not be broken there. [4] This week it is Spain that will be particularly exposed. [4] A very warm air mass from the Sahara has settled over the Iberian Peninsula, and temperatures can creep up toward 47 degrees in several places in Spain in the coming days. [4] A powerful so-called heat dome of high pressure has parked over southwest Europe and is pumping bone-dry desert air northward. [4] According to the Spanish meteorological institute Aemet, this is the third heat wave in Spain this summer. [4] The heat is expected to peak on Thursday. [4] Andalusia, the Ebro Valley and inland Mallorca are set to get the highest readings, with maximum temperatures over 40 degrees for several days in a row.

Increasing Frequency of European Heat Waves
Heat waves in southern Europe are becoming more frequent and longer-lasting, extending into May and increasing wildfire risk due to lack of significant rainfall. [4] The frequency and duration of heat waves are increasing in southern Europe. [4] The difference is that they come more often and last longer. [4] There is a frequency and a duration that is increasing. [4] Already in May there was talk of a heat wave, which shows that the season is becoming very long. [4] Heat waves used to stay in July and August. [4] What is dangerous is the temperature, but also that no significant precipitation is expected. [4] Then it can become dry and increase forest fire danger. [4] There are many aspects here. [4] As far ahead as can be seen, there is no end to the heat wave. [4] It can last a while. [4] Otherwise in Europe there is normal summer temperature. [4]
What to watch next: The heat is expected to peak on Thursday in Andalusia, the Ebro Valley and inland Mallorca, with a small dip over the weekend before heat returns next week, especially Thursday and Friday and at the turn of the month.
