January 2014
Last month's record rainfall was exceeded this month to achieve a new record of 165.8mm.  Serious flooding occurred on the Somerset levels, reaching national and international news.  Detailed analysis is given below.

December 2013
The wettest month in over 6 years at 142.7mm, just above the figure for December 2012. The weather has been mild with southerly winds and a succession of low pressure areas, causing significant damage and flooding across the UK.  The 23 Dec was particularly bad with 36mm of rain and 100kph wind gusts recorded here.

October 2013
A very wet month - at 126.9mm it is the second wettest month in the last 6 years.  The "St Jude" storm on the 28 Oct caused widespread damage and disruption across the south of England.  Weather reports suggested that Lydford was close to the centre of the low pressure system where winds were not as strong, and so we were lucky and suffered no damage.  It was a close thing, as Yeovilton is only 9km south of us and recorded a 76mph gust.

July 2013
Began hot and dry - no rain for 21 days from 2 to 22 July, ended with thunderstorms.  High temperatures up to ~34C causing distress to some plants.

December was the wettest month for the last 5 years, at 140.7mm.  Very serious flooding occurred throughout the country and Somerset fared badly.  The fields are saturated, so that any further rain causes immediate run-off into adjacent property.  On 21 November 2012, very heavy rainfall causes floods throughout Somerset and the west country.  Lydford escaped lightly with "only" 42mm, compared with Okehampton's 92mm.  Very high wind speeds all day with a peak gust here of 105kph (65mph).  Many roads flooded and/or impassable.  Seriously flooded roads encountered between Baltonsborough and Wells.  River Brue at Lydford is up to the bridge arches again (see pic of May 2012 below).

The recently repaired lower weir at Lydford is seen here on 21 Nov 2012.  The water in the foreground is ~20feet deep. Image on right is same weir on 18 Nov.

August 2012 rainfall was 110.9mm, the wettest August since we started measurements in 2007.

29 August 2012 - a heavy band of rain passing through west to east depicted here.  This is called a line echo wave pattern. The pin indicates Somerton.  We recorded 30mm of rain that day.
