Rare September Heat Wave Scorches Europe Meteorological summer is over in Europe, but a rare and extraordinarily intense heat wave has kept its grip on much of the continent during early September. Hundreds of European cities broke all-time September heat records the past three days; some stations with long periods of record exceeding a century saw their records smashed by 7 - 8°F--"a margin rarely seen before in the world," in the words of weather records researcher Maximiliano Herrera, who has been tabulating the new records.

The water level of the Vistula, Poland's largest river, is at its lowest level since measurements began in 1789, due to severe drought conditions. The treasures being excavated were looted by an invading Swedish army in the mid-17th century and got buried in the Vistula when a Swedish barge sank. Jewish tombstones and wreckage from a WWII fighter plane have also been uncovered this summer from the Vistula and its tributaries due to the low water levels.

September 1, 2015: a rare day in the annuals of climatology The carnage began on September 1, with September national heat records falling in eight countries. Notably, the new national heat record set in Lithuania was more than 3°C (5.4°F) higher than the previous September record--an astonishing margin for a monthly national record in a nation with dozens of reliable stations with a period of record extending back nearly 150 years. Here are the eight nations that set new September all-time heat records on September 1, 2015, according to Maximiliano Herrera:
Moldova: Tiraspol, 38.4°C (101.1°F) Ukraine: Voznesens'k, 38.8°C (101.8°F) Austria: Pottschach, 36.0°C (96.8°F) Czech Republic: Javornik, 37.4°C (99.3°F) Slovakia: Michalovce, 36.4°C (97.5°F) Poland: Tarnow, 36.8°C (98.2°F) Belarus: Zitkovici, 35.6°C (96.1°F) Lithuania: Druskininkai, 35.1°C (95.2°F)
All-time September heat records were smashed at individual stations in many other countries, including Russia, Romania, Bulgaria, Serbia, Montenegro, Macedonia, Kosovo, Bosnia and Herzegovina, Croatia, Slovenia, Italy, San Marino, Hungary, and Germany, with 48 stations in Germany alone setting new all-time September heat records (thanks go to Dr. Michael Theusner for this stat.) Some stations with more than a century of data even managed to beat their ABSOLUTE records for any month.

September 2 and beyond: more record heat The incredible heat continued on September 2, shifting eastwards some, with a 38.6°C (101.5°F) at Falesti, Moldava beating that nation's all-time September heat record set just the previous day. Ukraine tied its national record, just set the previous day. The extreme heat backed off considerably on September 3 and 4, but will build back in again over Southeast Europe over the weekend, with more all-time September heat records likely to fall.
European drought cost this summer: $2.7 billion It's been a incredible summer for extreme heat in Europe, with Germany setting its all-time heat record (twice), and with hundreds of stations having long periods of record setting all-time heat records. The heat has been responsible for hundreds of heat deaths in Europe, and according to the August 2015 Catastrophe Report from insurance broker Aon Benfield, drought in Romania, Poland, and the Czech Republic this summer has cost at least $2.7 billion--just below the $3 billion price tag of the California drought.
We’ll be back with an update on the tropics on Saturday. Have a great Labor Day weekend!
I'll be on the Weather Underground TV show ( #WUTV on Twitter) tonight on The Weather Channel. The show airs between 6:00 and 8:00 pm EDT. If you don’t have access to TWC on cable, you can still access selected clips from each episode, live streaming of online-only content, and a WUTV chatroom, all on the Weather Underground WUTV website.
