Andorra has registered a new record of days in a heat wave situation before the end of the month of July. between the On June 21 and July 24, four heat waves were recorded who have left a total of 23 days with extreme maximum and minimum temperatureslocated above the percentile 98 of the historical series of the weather station of the hydroelectric plant of FAITH. This threshold corresponds to two percent of the warmest values recorded in this series.
This record exceeds the maximum achieved so far in this station, which corresponded to the summers of 2022 and 2023when they were counted 17 days in a heat wave situation. In this way, this year they have already exceeded in six days the previous recordsalthough the month of July has not yet ended.
The number of heat waves recorded this summer is four, a figure that equals the maximum reached in the years 2022 and 2023. The difference, however, is in their persistencewith a much longer duration than that recorded so far.
The data also confirm a trend of increasing episodes of extreme heat in the country. Until the year 1988 had not registered no heat wave at FEDA central station and the 2016 was the last summer without this phenomenon.
Since 2017, Andorra has chained together ten consecutive summers with at least one heat wave, an evolution that highlights the increase in both the frequency and the persistence of these episodes of extreme temperatures. Between June 21 and July 24, 23 of the past 34 days have been in a heat wave situationan unprecedented persistence since records have been available at this weather station.
The situation this summer is explained by the persistence of the anticyclonic ridge, which has been accompanied by several episodes of Saharan dust invasion. This phenomenon has been combined with the smoke coming from the important fires declared in France i Spaincontributing to particularly exceptional atmospheric conditions.
