Second summer heatwave hits this weekend: Spain weather forecast July 6-9
Extreme temperatures in the high 30s and low 40s will persist across Spain well into next week
A cold air front brought a little reprieve from the high temperatures earlier this week, with parts of Catalonia and the Valencian Community even experiencing heavy hail storms, but all that is about to change with the second heatwave of the summer.
While predicting these extreme weather events is still something less than an exact science, the State Meteorological Agency (Aemet) expects a warm air mass from North Africa to sweep in over the weekend and early next week, heralding temperatures well into the 40s.
Although the start of the week saw temperatures more usual for this time of the year, the heat will begin to ramp up on Friday July 7 with the promise of plenty of thundery spells and heavy rain in parts.
We can expect "very high temperatures in the east and south of the Peninsula, and in the Balearic Islands," according to Aemet spokesperson Ruben del Campo, who has cautioned that "there is still uncertainty about the areas that could be most affected and the duration of the episode."

Thursday July 6 will be generally dry in most places although cloudy skies and scattered showers and storms will persist in northern Spain that could intensify as the day goes on. The morning will begin overcast in the east and southeast, but this will clear throughout the day.
It will be a rather hazy start in the south where the temperatures will drop somewhat, while taking a noticeable upswing practically everywhere else.
Yellow alert for high temperatures: Andalucia.
Yellow alert for heavy rain or storms: Castilla y Leon, Catalonia, the Basque Country and La Rioja.
Orange alert for heavy rain or storms: Aragón and Navarra.
"On Friday the winds will begin to blow from the south, carrying a mass of warm air that will raise temperatures, especially in the northern third of the Peninsula," the spokesperson explained. However, this temperature hike won’t be noticed in eastern provinces until Saturday while the mercury will jump upwards everywhere from Sunday.
Abundant low morning cloudiness is expected in large areas of the north and northwest of the country on Friday July 7, as well as inland in the southeast and around the Strait, giving rise to probable mists or fog banks that should break up later in the day.
Large parts of southern Spain will see the thermometers exceed 34-36ºC, especially the valleys of the southwest.
Yellow alert for heavy rain or storms: Aragón and Navarra.
Much of northern Spain will remain overcast and stormy on Saturday July 8, with possible calimas or Saharan dust clouds forecast in Melilla and parts of the Mediterranean coast and Balearic Islands later on.
Daytime temperatures will increase in the Balearic Islands and in the south, and especially along the eastern coasts.
On the other hand, it will be noticeably cooler in the northwest and in the Bay of Biscay.
Sunday July 9 will be a clear and sunny day across the board with the exception of Cantabria and Galicia, where some more scattered showers and cloudy skies are forecast. Here, the temperatures will also fail to rise although the mercury will shoot up everywhere else, easily exceeding 35ºC in much of southern Spain and the Balearic Islands and tipping over 40ºC in the Guadalquivir.
If the heatwave does materialise over the weekend, Aemet believes it could last well into next week, with Andalucia expected to bear the brunt and swelter in temperatures as high as 46 or 47ºC.
In fact, the preliminary forecast for Monday July 10 suggests that Seville could hit 48.2ºC, which would beat the national record of 47.6ºC currently held by Cordoba.
