There are no precedents for such a warm phenomenon at this time of the year in Spain. At least not since 1950 have there been records of an autumn episode as “unusual and intense” as the one expected over the next few days, with temperatures more typical of mid-August than autumn, as reported by Ruben del Campo. The spokesperson of the State Meteorological Agency (AEMET).
In an interview with EFE, del Campo explained that from next Friday to Wednesday, the peak days of this episode, 30-32 degrees could be reached in large areas of the country, between 32-34 degrees in the Ebro valley and the southwestern peninsula. , and in the Guadalquivir valley up to 36-38 degrees.
October is the warmest
The maximum temperature recorded in Peninsular Spain for October is 37.5 degrees in Marbella (Málaga) on the 22nd of the month of 2014, as recorded by the National Climatic Data Bank. The second record is only one-tenth lower than that set on October 2, 2004 in Andujar (Jaen). “According to forecasts, it is possible to exceed these figures in the coming days,” the meteorologist said.
However, he explains that one cannot talk about a heat wave in the strict sense until more than 95% of the series of maximum daily temperatures for July and August of the period 1971-2000 have been recorded. This episode “will not have the trouble” of a mid-summer heat wave, but it is “unusual” from a climatic point of view to be so hot on these dates, as the 36-38 degrees showed. It is predicted in the Guadalquivir areas.
This very anomalous situation is the result of several reasons: on the one hand, the atmospheric stability that favors the clear sky, the sun shines and heats the surface very much, and on the other hand, the air mass that comes from subtropical latitudes. Unusually warm, scheduled from September 28 to October 4.
So far, the warmest days will be between Friday, September 29 and Monday, October 2, with maximum temperatures of 32 to 34 degrees in large areas of the peninsula’s interior, while the Guadalquivir Valley could exceed 36 to 38 degrees. degrees. “The heat will descend” on the Canary Islands this weekend, with maximum temperatures that could be around 34 or 36 degrees in the eastern islands.
When is this episode expected to end? “Today’s forecast looks like temperatures will begin to drop on Wednesday, October 4 or Thursday, October 5, but it is impossible to pinpoint the end of this extensive and prolonged unusual heat wave for the season.” Reuben Dale Field.
For this Wednesday, a “significant increase in temperatures” is expected along the Cantabrian coast, less pronounced in other parts of the northern half with 30 degrees in the eastern Cantabrian Sea, the Ebro depression, the central area of Castilla y León and much of the center and south of the peninsula, while it will reach 34 degrees or more in points of the Guadalquivir.
During the day, the temperature will be 5 to 10 degrees above normal in most of the area, and on Thursday it will be mostly longer, although the temperature will rise slightly in the southern half on this day, while the rest will remain unchanged.
