After a week of instability, storms and hail, the summer heat arrives. Just this weekend, the lightning detection network of the State Meteorological Agency (Aemet) recorded 23,000 rays between Saturday and Sunday.
But, with some exceptions, this week the summer heat finally sets in, with temperatures that can reach in some areas at 40 degrees Celsius. “Fully summer heat,” according to Rubén del Campo, a spokesman for the agency.
This heat comes from this Monday and at least until friday, when the more widespread arrival of storms and increased atmospheric instability are expected. Until then, hot day and night. “Also we will have tropical nights, those in which the minimum temperature does not drop below 20 degrees, especially in Andalusia, Extremadura, western Castilla-La Mancha and the Mediterranean coast “.
Del Campo has highlighted that temperatures rise again until the middle of the week in the Guadalquivir valley will touch 40ºC In the Canary Islands, very hot days are also expected, especially in the south of Gran Canaria and Fuerteventura, where it will probably exceed 36ºC and even 38ºC.
In addition, he has advanced that from Friday instability will possibly increase, especially in the central zone and in the northern half, where stormy showers will occur.
Temperatures have started an escalation that will bring highs of 40 ºC to the Guadalquivir depression 🥵. Nearby will be Badajoz or Zaragoza.

Stable time in the week
Looking ahead to this first half of the week, the spokesman explains that the weather will be “calmer” than last week, although they can also form storms in mountain system environments, which can also be locally intense, but in general the showers will be occasional and scattered.
Specifically, the Tuesday will be a stable time shift, with skies generally slightly cloudy or with some intervals of clouds and from midday the cloudiness of diurnal evolution will increase that can lead to showers accompanied by storms, especially in the environment of the Iberian system, that is, in the south of Aragon, northeast of Castilla-La Mancha and north of the Valencian Community.
Showers, he explains, could be locally strong and accompanied by hail and an intense Levante wind will blow in the Strait and with strong gusts of trade winds in the Canary Islands.
I know will exceed 32 to 34ºC in the interior of the Canary Islands, where they will have haze, that is, dust in suspension and in the rest of the Peninsula they will also rise in a generalized way, both during the day and at night.
In the Peninsula, it will exceed 30 to 32ºC in many areas of the Ebro valley, in the south of the Community of Madrid, Extremadura, western Castilla-La Mancha and in a good part of Andalusia, where 34ºC and even 36 and 38ºC will be exceeded in the Guadalquivir valley.
Wednesday and Thursday
With respect to Wednesday and Thursday has said that it will continue the same trend of stable environment, in general, with slightly cloudy skies in the morning and development of clouds of diurnal evolution from noon, which again in the surroundings of the Sistema, Iberico and Pyrenees they can lead to stormy showers. Nor does it rule out that these showers and storms affect other mountain areas in the center and east of the Peninsula.
The Levante wind will continue to blow with intensity and there will be no changes and the temperatures on those two days will drop slightly in the north, but will remain unchanged in the rest of the country.
“To be continued intense heat of midsummer, especially in the west, center and south of the Peninsula, and will even touch 40ºC in some points of the Guadalquivir valley “, says Del Campo, who observes that will produce “many” tropical nights.
In the Canary Islands it will be very hot, together with airborne dust, and they will exceed 36 to 38ºC in southern parts of Gran, Canaria and Fuerteventura.
In short, the AEMET spokesperson estimates that maximum temperatures will be 5-10 degrees Celsius above normal in a good part of the west, center and northeast of the Peninsula as well as in the south.
The thermal anomaly will also be between 5 and 10 degrees above normal in the interior of the Canary Islands. I only know will free the Cantabrian coast from these hot temperatures, where on Wednesday and Thursday the atmosphere will remain cool, with highs between 20 and 23ºC.
Instability on Friday
As of Friday, there may be a further increase in instability that will lead to the development of evolution clouds in the interior of the Peninsula, where showers will occur accompanied by storms, especially in mountain areas and those around them.
The temperatures will drop although the heat will continue, especially in the Ebro, Guadiana and Guadalquivir basins, although this heat will already be more moderate. In the Canary Islands, the thermometers will mark normal for this time of year from Friday, when the trade winds will return to the archipelago and the normal temperatures on the islands will recover.
