I’m a bit hampered today by a head cold, and so today’s post will be a short one.
The preliminary report for September weather in Switzerland is out. Hat-tip: Kurt in Switzerland.
According to the Swiss Meteorological and Climatological Office, September was 0.8 deg. Celsius colder than the norm for the month, based on the averages for the period of 1981-2010. A blast of polar air early in the month saw temperatures plunge to as much as 7°C below normal. Snow fell at elevations down to 1800 meters.
Later in the month temperatures fell once again, dropping to as much as 7°C below normal in the Alps. The snow fell to elevations as low as 1400 meters on the north side of the Alps.
Interestingly in Swtzerland this year the autumn crocuses blossomed more than week earlier than the 1981-2010 mean. The Swiss Met office writes that “in many areas the blossoms were already observed in August“. Also foliage colors from a variety of trees were observed to be earlier than normal, writes the Swiss Met.
Holland sees coldest September in 15 years
Also reader Vermeer writes in a comment that the Netherlands had it coolest September in 15 years. The mean temperature in De Bilt was a nippy 13.4 °C , 1.1 °C below average. There were only two days with a maximum above 20°C. Highest only 20.2 °C. This was the lowest high September maximum in 50 years.
