Compare the temperature of each day with the historical average of your province

Which province has the highest temperature that is furthest from what would be expected for the season? Is there a province that is having the warmest year since records began? What is the trend over the last decade? How many records have been broken? You can check all this data on the map above. Click on the buttons and check how your province is doing.

What do we compare with? AEMET considers the years between 1980 and 2010 as a reference period to calculate the “normal temperatures” in each territory. Depending on the difference between the average for that period and current records, it is possible to see whether it is warmer today, in 2024 so far or in the last 10 years compared to what would be normal.

The following table ranks all the provinces according to the degrees above or below which their highest temperature in the last 24 hours is compared to the historical average calculated for the current month and also the same calculation for the average maximum temperatures so far this year. In addition, we have added a new calculation to compare the evolution of temperatures in the last decade compared to the historical average in each province.

This heat is not normal

Compare the temperature of your province with the historical average. Difference, in degrees (ºC), between the maximum temperature of the last 24 hours and the annual average compared to the historical average for the period 1981-2010

Much hotter than usual

The current heat is not just a one-day thing. To see if temperatures in 2024 are really higher than usual, we compare the maximum temperatures recorded so far this year with the reference period.

Scientist Ed Hawkins popularized the use of climate stripes, bar code-like graphics SSSSSSSSSS which record the evolution of the average temperature of any place, compare it with the average for each year and display it with a colour code.

How does global warming affect your province? In the following graph you can find out how far the average maximum temperatures have been from January 1st until today in each year compared to the average from 1980 to 2010. In other words, a reflection of global warming at each AEMET meteorological station.

Global warming is a phenomenon that affects the entire planet and the data from the AEMET stations reflect this for Spain. The gradual increase in the maximum temperatures reached each year is repeated in all Spanish provinces.

Is 2024 being particularly hot in your area? To see in more detail how this phenomenon is repeated throughout the country, the following graph shows how far the average maximum temperatures in each year are from the historical average (1980-2010). For 2024, it is compared only with the historical average of maximum temperatures for the same days so far this year.

The climate crisis affects all of Spain

Difference, in degrees (ºC), between the average maximum temperatures of each year and the annual average between 1981-2010. For 2024, only the historical average for the period between 1 Jan. and 23 Jan. is compared.

To put the daily maximums for 2024 into context, the following graph shows the evolution of the daily maximum temperature in each province, but also the value that would be normal for that day of the year and the highest and lowest extremes previously recorded. The menu allows you to check the evolution of the maximums in any province.

For this article, historical data on maximum temperatures collected by the State Meteorological Agency (AEMET) since 1950 (or from the first subsequent year available) have been used, extracted from its API and analysed by elDiario.es.

The data for each province correspond to the meteorological station located in the capital of each province that has current observations and the oldest historical series. In their absence, another station in the province with the same characteristics has been used (for example, the data for Palencia correspond to the Autilla del Pino station).

In the cases of Cantabria, Gipuzkoa and Álava, the data from the last 24 hours do not come from the same station as the historical data used for that province, since there is no station that shares all the data. However, these are stations located a few metres apart at the airports of these provinces. The temperatures collected by both do not always coincide, due to the conditions of the environment where they are located, but the variation is a few tenths and that is why they have been used for the comparison.

Secondary stations, apart from those classified as provincial capitals, have also been included, those with a historical series without large time jumps, with data since at least 2000 and which continue to record temperatures today.

The average of the maximum temperatures between 1981 and 2010, of the month or the days of the year that have passed until the update date, is used as a reference indicator for the “normal temperature”. This is the time period considered by the AEMET to “define the climatic characteristics of a given area”.

For the temperature record indicators that have been surpassed, this medium classifies them as a record when the maximum temperature reached in the historical series in that same month or in an absolute manner is exceeded.
