Will Spain witness its first heat wave this week?

Weather calculations in Spain indicate that the temperature will rise sharply in the coming days, and peaks will exceed 40 degrees. June can end up being very hot all over Spain. Wednesday is the last day of precipitation in many regions, especially in the northern and eastern part of the country. From that moment on, the chance of rain is greatly reduced.

High pressure areas make their presence known by bringing in warm air from the African continent. On Thursday, the first temperatures above 35 degrees will be measured in the Guadalquivir Valley, and 30 degrees will be exceeded in many areas of the southern part of Spain.

In the south, but also in the north of the Spanish mainland, the temperature will easily exceed 35 degrees, while the rest of the mainland will see temperatures above 30 degrees. It looks like the extreme heat will continue through Tuesday, June 27th. After that, temperatures stabilize to the usual warmth for the season.

During the night hours, high temperatures will continue, resulting in what we call tropical nights. In certain parts of Mediterranean Andalusia, Inland Andalusia and Extremadura, the temperature can’t even go below 25 degrees, making for very warm nights.

The Canary Islands will also be affected by these high temperatures. Heading into the weekend, temperatures above 35 degrees can be expected in the interior of the islands, especially in the eastern islands.

Heat wave or not?

However, it is not officially a heat wave, as it does not meet the criteria for intensity and duration. By Spanish standards, a heat wave is present when temperatures of 33.3 degrees or more are measured on 3 consecutive days. This is 2 days less than in the Netherlands and Belgium, where a period is referred to as a heatwave when there are at least 5 consecutive days with temperatures above 25 degrees or at least 3 consecutive days with temperatures not below 30 degrees. Temperatures of 25 and/or 30 degrees are considered normal in Spain in the summer because they occur more often than in the Netherlands and Belgium.

The Spanish weather service Aemet literally says the following: “An episode of at least three consecutive days in which at least 10% of weather stations record maximums above the 95% percentile of the series of daily maximum temperatures for the months of June, July, and August in the period 1971–2000.”
