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.
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.
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
December was the wettest month for the last 5 years, at 140.7mm.
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).
