Geneva: Switzerland has just experienced its driest December in more than 150 years and one of its driest months on record, meteorologists said Saturday.

With an average of just 2.0 millimetres (0.079 inches) of precipitation this month, the Swiss lowlands saw their driest month since record-taking began in 1864, the Federal Office of Meteorology and Climatology called MeteoSuisse, told public broadcaster RTS.

Many places in the west of the country did not see a single snowflake or drop of rain, it said, pointing out that usually the Swiss plains get nearly 90 millimetres of precipitation on average in December.

Before this year, the driest December on record was in 1963. The Swiss lowlands saw an average of 4.8 millimetres of precipitation.

The usually wet month of December ticked in this year as the third driest month on record, after September 1865, which saw 1.7 millimetres of rain, and April 1893, which got only 1.1 millimetres.

Meanwhile, many places in the Swiss Alps experienced unusually high temperatures, with the 3,466-metre (11,371-foot) Jungfraujoch peak for instance registering its third-warmest December on record, MeteoSuisse said.

The meteorologists did not provide an explanation for the unusually dry and warm weather.
