Summer days (SU25)
Summer days (SU25): annual count of days when daily maximum temperature is greater than 25 °C (TX > 25 ºC). The unit of measurement is “days”.
The evolution of SU25 anomaly (ASU25, difference between the annual value of SU25 and the mean value of SU25 in the reference period 1981-2010) during the period 1959-2020 is shown for the Pyrenees and for 4 areas of the Massif (Northern Pyrenees, Southern Pyrenees, Mediterranean Pyrenees and Atlantic Pyrenees); for each of the 12 series analyzed, the evolution of SU25 index is shown.
The annual mean of SU25 for the Pyrenees is obtained from the annual SU25 values of 12 representative series of the Pyrenees massif (areas at different altitudes and on all slopes: north, south, east or Mediterranean and west or Atlantic), while the mean value of SU25 for the 4 zones of the Massif is obtained from the annual SU25 values of the representative series located in each zone.

Evolution of the annual SU25 anomaly (ASU25, in days) in the Pyrenees for the period 1959-2020. Red points (positive ASU25) indicate a SU25 value higher than the reference period value and blue points (negative ASU25) indicate a SU25 value lower than the reference period value.
The dotted line shows the linear trend of the series (+4,3 days/decade).
