Global warming brings with it abnormally high temperatures. Autumn enters the northern hemisphere today at 22:02 and will begin with high temperatures. Spain is in a water deficit, even ending the hydrological cycle.
Rainfall is not expected to overcome the water deficit, as the precipitation forecast for the fall months is not very promising. What will fall 2017 be like? To learn more about what to expect this season, you can read about What autumn will be like in Spain.
More temperatures and less rain
As the years go by, temperatures are getting higher. Winters and autumns are milder and with higher temperatures. Furthermore, rainfall is declining and is not sufficient to recover the water used in reservoirs across the peninsula. Although a third of the annual rainfall is usually collected during the autumn months, for the time being, climate projections foresee an October with less rainThe lack of rain expected for the month of October will impact mainly areas of Extremadura and southwestern Andalusia, and to a lesser extent areas of the Mediterranean. For a more detailed analysis of the weather conditions, you can visit the article on the year 2017 and its temperatures and read about the winds that affect Spain.
However, some hope will come in November and December, when there will be more rainfall. The rains will be felt across most of Spain, being heaviest in the Basque Country and the Balearic Islands. It is also important to consider warm fronts that contribute to these changes in the climate.
Autumn with more temperature
As mentioned before, a fairly warm autumn is expected, with high values and anomalies between 1 and 1,5 degrees above average. For the month of November, 9,9 degrees are expected on average (which is quite warm for all of Spain) and in December with 8 degrees on average, also quite warm. This increase in temperatures is a trend that is also observed in other parts of the world and can be related to the global warming. Furthermore, it is important to consider Curiosities about this year's autumn which may also be of interest.
The summer has been very hot
As for the summer that will end on Friday, it has been the second warmest since 1965 and also in the 2003st century, behind the summer of 25 in which the average temperature was 2015 degrees, being above the summers of 2016 and XNUMX , those it has exceeded by 0,2 and 0,5 degrees, respectively.
This summer, quite a few temperature records have been broken. For example, in Córdoba 37 days have been recorded in which the temperature has exceeded 40 degrees. This was already coming when June started extremely warm, the warmest since 1965, with average temperatures 3 degrees above normal. July and August exceeded average temperatures by 1 degree. This data is indicative of a exceptionally hot summer in Spain and are complemented by forecasts for the Mediterranean region.
During the summer season there were three heat waves: the first between June 13 and 21, the second between July 12 and 16, where the highest summer temperatures were recorded, and the one that ran between days 2 to August 6.
Among the highest temperatures recorded on heat wave days in July, we find 46,9 degrees in Córdoba. In addition, in 16 main stations throughout Spain, the average temperature this summer was the highest in its series since 1920.
Rains during this summer
At least, during this summer there has been rainfall 79 liters per square meter averages. This value is 7% higher than the average.
It was wet or very wet in the central Iberian Peninsula, the Basque Country, La Rioja, Navarre, and Aragon, dry or very dry in parts of the southern Iberian Peninsula, Catalonia, Galicia, western Castile and León, and the western Canary Islands, and extremely dry in an area that includes western Andalusia, southeastern Extremadura, small areas between Granada and Albacete, and the western Canary Islands. Although rainfall averaged 7% above normal, it was not enough to offset the water deficit. The hydrological cycle closes with a deficit of 12%. The more heat, the more water consumption and more amount of water evaporation, so the amount of dammed water is drastically reduced in all reservoirs in Spain.
Let's hope the rains return and the reservoirs can be recovered, as they are in an increasingly depressing state. Water restrictions should be started in many places where reservoirs are below 30%.
