While super-tropical days also occurred in the past, their incidence has been higher and has exhibited greater regularity since 1990.
“The greatest number of such days - 15 - in Hurbanovo (Nitra Region) was recorded in 2012,” said the Slovak Hydrometeorological Institute (SHMÚ) as cited by the TASR newswire.
There have been 11 such days this year measured at a weather station in Hurbanovo up until the end of July.
“This number will have increased after August 6, and it’s certainly not ruled out that the absolute record in this respect - since 1901 at least - will be broken,” said SHMÚ.
Interestingly, although 2014 was the hottest year in history, there was not one super-tropical day last year. 2012 also saw the highest number - 10 - of tropical nights - i.e. those with the minimum nightly temperature not falling under 20 degrees Celsius. This record, too, is very likely to be broken this year, as there were seven such nights already by the end of July.
Slovakia is now experiencing a third heat wave this year with temperatures not expected to drop until next Monday. For August 12 SHMÚ has already issued the highest warnings for all districts of Slovakia when the temperature may climb as high as 38 degrees Celsius.
