“The summer atmosphere will continue for the next few days, tinged with sunshine due to some rains in the Cantabrian Sea and storms in mountain areas,” explains the spokesperson for the meteorological agency, Rubén del Campo.

A heat wave?
The experts from the State Meteorological Agency have not described these two days of high temperatures as a heat wave. In fact, due to the high figures that mercury is marking in some parts of the country during these days, meteorological experts have published a study that analyzes the heat waves that have crossed Spain in recent years, and have taken advantage of to accompany it with a new definition for this term, because as they explain, there is no “single, precise definition for this term“, till the date.
“When establishing temperature thresholds, it must be considered that the ‘normal’ values of these differ greatly from one area to another, and therefore, the same limit cannot be established for all the stations considered and also that thresholds are too lax they would result in the number of episodes of ‘Heat Wave’ each summer being very high, thus losing the exceptional character that they are supposed to have, while if they are too strict they might not detect some episodes, “they explain from Aemet.
Thus, the experts of the state agency have concluded by define ‘Heat Waves’ as follows: “An episode of at least three consecutive days is considered ‘heat wave’, in which at least 10% of the stations considered record maximums above the 95% percentile of their series of daily maximum temperatures for the months of July and August of the period 1971-2000 “.

In addition, in 2017 another five were registered, the most pronounced being the one that took place between days August 12 and 16 and that affected 14 provinces where it reached 41.1ºC, the maximum temperature recorded in the historical series of waves collected by the Aemet that contains data since 1975.
