“Positive deviations of air temperature from normal ones equalled as much as three or four degrees Celsius,” reads an analysis from the Slovak Hydro-meteorological Office (SHMÚ) as cited by the TASR newswire. “Values of even one degree Celsius in terms of positive deviations are already abnormal.”
One characteristic of the summer of 2015 was an extremely high number of days when the maximum air temperature reached 35 degrees Celsius or more.
“In the most exposed places there were more than 20 such days, an all-time first in the history of meteorological measurements,” reads the document.
The same holds for the number of days on which the minimum air temperature did not drop below 20 degrees Celsius. A total of 26 such days were recorded in Bratislava’s Koliba borough between June 1 and August 31.
Also noteworthy was the number of tropical days in northern and northwestern parts of Orava and the Poprad basin, areas that are at higher altitudes and where such days had previously never occurred. This summer the number of such days reached double digits, however.
