Yesterday we posted here how Germany’s DWD national weather service reported that September 2015 was cooler than normal. The United Kingdom saw one of its coolest Septembers in decades.

The Austrian ZAMG national meteorological services released the temperature results for September 2015 here. Looks like the country is getting an early start to the ski season. It writes:

The preliminary monthly result of the ZAMG: September 2015 pretty much hit the multi-year mean (0.1 °C below normal). Rain and snow were 20 percent above normal. The sun shone 15 percent less than it usually does over an average September. A September with wide temperature fluctuations has come to an end. On September 1 the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) measured the hottest September day in the history of measurements: 36.0 °C in Pottschach. In the second half of September a cold mass of air brought snow down to many valleys. Early on 24 September in Bad Gastein (S, 1092 m), for example, there was 8 cm of snow. At the Rudolfshütte in the Hohen Tauern (S, 2317 m) there was 45 centimeters of snow. ‘On average, however, the extreme temperatures yielded a very average month,’ says ZAMG climatologist Alexander Orlik. “Looking at Austria as a whole September 2015 was 0.1°C below the multi-year normal.'”

Urban heat island effect in Vienna?

Interestingly the ZAMG data show that remote locations saw cool anomalies, for example with Achenkirch (T, 904 m) coming in at

0.8°C below normal. The warmest anomaly was recorded in the city center of Vienna (W, 177 m), coming in at 0.3°C above the long-term mean for September.
