There was a stream of hot air coming in from the Sahara. This happens every now and then. Combined with concrete of the city it can indeed become very hot. After 3 days of record heat the weather in most parts of Europe is back to normal. The worst thing about it not the heat, but the lack of ACs in Europe.
" The Met Office announced the 38.7C figure was received from Cambridge Botanic Garden yesterday*. If validated, it will become the highest temperature officially recorded in the UK, outstripping the 38.5C seen in Faversham, Kent, in August 2003." Global warming for sure! . *Thursday 25th July.
It is indeed hot wind from the Sahara and that does indeed happen from time to time. Standing on its own, the current heat wave is nothing unique (apart from the heat records). This year however, heat waves has happened over two consecutive months though, each time with record breaking temperatures! There was a European heat wave in June and now again in July. Looking at a list of heat waves worldwide (probably not exhaustive) there have been more and more heat records in "recent" years. Its probably nothing more than just a weird coincidence! June 2019 was the highest ever recorded earth average temperature, with July expected to beat that! Anyone interested in understanding the arctic should visit polarportal.
Friday, Sweden had its annual heat record at 34,8 'C. One would expect that to be in the deep south, closer to the source of the "Saharan winds", but nope, it was in the high north, just north of the arctic circle in the village of Markusvinsa, Pajala municipality. Bergen, Norway, also set a record high temperature Friday at 32,8 'C.
The heat is now forecast to continue to Greenland and create temperatures in the mid twenties as opposed to the normal maximum 15-17 'C, with further increased melting of the inland ice. During the 70s and 80s Greenland lost an average 50 billion tons of ice per year due to surface melting. From 2010 that increased to 290 billion tons per year, on average. In the month of June 2019 alone, the loss of surface ice in Greenland was estimated at 80 billion tons and the yet unfinished month of July 170 billion tons - supposedly the amount of water that pass through the Niagara falls during 1 year and 9 months! So year, everything is "great and normal" if we look at the heat wave as a single occurrence.
PS. Increased usage of AC units is not a solution to a repeated, increased pattern of heat waves, but rather a plaster of comfort. If anything, the increased use of energy-heavy electrical gadgets can only contribute even more to the problem, not to mention increased mining activity, deforestation, processing, shipping, etc. AC is a plaster, not a cure.

Norway equaled its national historic heat record with 35.6°C at Laksfors, more than 65°N of latitude tied with the 35.6°C of 20/06/1970 at Nesbyen (Buskerud), more to the south. Mercury reached at least 34.6°C in Saltdal, the highest temperature ever measured north of the Arctic Circle in Norway. Bergen recorded a record high of 33.4°C on Saturday, an all-time record high of 32.2°C on July 27, 2018. It was 32.4°C in Trondheim, which marks its fourth consecutive day of more than 32°C.
In Finland, temperatures reached up to 33.7°C in Porvoo yesterday. Helsinski broke his absolute heat record with 33.2°C recorded at the Kaisaniemi reference station (previous record: 31.6°C on July 18, 1945). In Tallinn (Estonia), 31.6°C was also recorded.
As Jan said, Greenland has also been suffering of heat.
