Swiss spring was third hottest on record

Switzerland has experienced its third warmest spring since records began in 1864, meteorologists have said.

The average temperature for the whole country was 1.7 degrees warmer than the norm for 1981-2010, according to MeteoSuisse
 
Only the springs of 2007 and 2011 were hotter.
 
That was in part because March was particularly warm, surpassing the norm by 3.3 degrees. 
 
April and May were also warmer than normal for the time of year, but to a lesser extent. 
 
That’s despite a swing to the other extreme in late April, when a cold snap brought ground temperatures right down to near record levels. In Vierge in the Valais the mercury plummeted to -5.5 degrees on April 20th, a record low for the area at that time of year.
 
The resulting frosts proved disastrous for fruit orchards and vines, which had started to flower during the earlier warmth and suffered catastrophic damage during the cold snap. 
 
 
Generally this spring was sunny and dry, with a higher percentage of sunshine and less rain than the norm.
 
Summer weather arrived in late May, with Switzerland experiencing its first ‘tropical’ night (meaning nighttime temperatures above 20 degrees) in the canton of Ticino on May 24th. 
 
A few days later a mini heatwave saw daytime temperatures shoot up across the country, with some parts surpassing the 30-degree mark. 
 
The news follows the trend of warmer weather and less precipitation in recent years.

Climate crisis: Swiss lakes at lowest-ever August levels

Some of Switzerland's best-known lakes are at their lowest level ever for August after a dry year so far in 2022, the environment ministry said on Wednesday.

Climate crisis: Swiss lakes at lowest-ever August levels

Some of Switzerland’s best-known lakes are at their lowest level ever for August after a dry year so far in 2022, the environment ministry said on Wednesday.

At the same time, discharge levels on the Rhine, one of Europe’s major rivers which starts in the Swiss Alps, have never been so low in August since records began.

“There is a low water situation in Switzerland, especially on the central plateau and in the southern part of Ticino,” the country’s southernmost canton, said Michele Oberhansli, from the Federal Office for the Environment’s hydrology division.

“The reason for the existing situation is a precipitation deficit in the whole year of 2022, which affects the whole of Switzerland, as well as many other European countries,” she told AFP.

Soil moisture is down across the country and drought is affecting forests and agriculture, she said.

Lakes Constance, Lucerne, Lugano and Walen “are currently recording water levels that have never been so low in an August month since measurements began”, said Oberhansli.

Meanwhile Lakes Zug and Maggiore “continue to show values well below average”.

The shores of Lake Maggiore mark the lowest point in Switzerland, normally at 193 metres above sea level.

Except the lakes in the Jura region in the northwest and Lake Thun, the levels of all the other larger Swiss lakes are also below the long-term average.

Rivers down, glaciers melting

Meanwhile many Swiss rivers are recording readings that only occur once every two to 20 years.

“Discharge values on the Reuss and Rhine have never been so low since measurements began in August,” said Oberhansli.

The hydrologist said rain over the coming days should “slightly alleviate” the low water and drought levels, but would “not yet be sufficient to ease the overall situation”.

Following a dry winter, the summer heatwaves hitting Europe have been catastrophic for Switzerland’s Alpine glaciers, which have been melting at an accelerated rate.

A layer of ice — 15 metres thick in 2012 — has covered the Tsanfleuron Pass between two glaciers since at least the Roman era.

But most of it has gone and the ice on the pass will have melted away completely by the end of September, a ski resort said last week.
