A 'goodbye' or'see you later' could be more appropriate. Temperatures will quickly climb once again.

| [Europe heat wave map 2022/Windy] |
Everyone is talking about this heat wave since it is one of the worst in recent years and it is setting records for both the highest and lowest temperatures that have ever been recorded. This wave is notable for its severity (with temperatures reaching 47 degrees Celsius on the Peninsula), its spread (nearly all municipalities have been issued warnings), and its tenacity, since its length is expected to surpass 10 days. How long is this heat wave expected to continue? There is a possibility of a "second portion," even if the temperatures decrease presently.
This prolonged heat wave will finally see its first temperature reductions begin to materialize this week. This coming Monday, temperatures will fall in parts of the western part of the nation, including Galicia, Asturias, and Extremadura, as well as some parts of Cantabria, Castilla y León, and Andalusia.
When does the heat wave in July come to an end? There will be a decrease in temperature across the board on Tuesday the 19th, but it will be most noticeable in the northern part of the country: the Basque Country might see temperatures up to 10 degrees lower than they were yesterday. It seems that the threshold for a heat wave will no longer be reached, but there will still be warnings for high temperatures present in the south and east of the nation, some of which will be orange.
Could be heat wave again
In any event, as temperatures fall in the eastern half of the country on Wednesday, they will already be on the rise again in the western half of the country: a rise that could be 8 degrees Celsius in certain locations in the south of Galicia, and a rise that could be 6 degrees Celsius in certain locations in Castilla y León and Extremadura compared to the previous day. Temperatures will also increase on the Canary Islands as a result of climate change.
Even if there may be a little interlude, it is possible that the heat wave that has been plaguing Spain since July 9 will go on into this week.
Although it is not anticipated that temperatures will reach record highs like they did the previous week, the criteria for a heat wave may once again be met with temperatures reaching 38 degrees Celsius in the central part of the country and coming dangerously close to reaching 40 degrees in the southern part of the region. It would seem that the northern region could be spared from the very high temperatures this time.
All indicators 'in red'
In the case of this episode, all three of the warning signs that we might consider in relation to a heat wave are shown in red:
'First of all, it is being a very powerful wave: 47 degrees have already been registered in the Iberian Peninsula, which is very near to the heat record in Spain, which took place last year, and in Portugal, which is 47.4oC. 'Second of all, it is going to be a very hot week. '
"On the other hand, the extension, because it is affecting practically all of the communities, despite having a greater incidence on the western and central zones, with the highest temperatures in the national territory in the surroundings of the Tagus, Guadiana, and Guadalquivir (up to 45 degrees Celsius)."
And finally, the period of the test, which is set at 10 days but may be increased to a greater extent. It is one of the variables that presents the greatest danger to health: several days of extreme heat followed both day and night, which does not enable us to relax effectively, particularly in cities owing to the influence of heat islands. This is one of the factors that poses the biggest risk to health.
Heat in the rest of the month
It is still impossible to determine exactly when the heat wave that began in July will come to an end. On the other hand, it is becoming more apparent that temperatures will remain above average for the remainder of the month. It seems that the drier and warmer than usual weather will be with us for a longer time, even now that the dog days have begun, which according to statistics and climatology is the period of the year that has the highest average temperatures.
