October 2016

The averaging period used for the following assessment was 1981-2010.

UK Overview

On the first day of the month a shallow depression tracked east across Wales and then England, bringing some rain, but after that all parts of the UK became predominantly dry, as high pressure took charge. For much of the time the high was centred over Scandinavia, bringing easterly winds, and restricting temperatures to near the seasonal average but with plenty of sunshine, especially in western areas. As the second week of the month progressed, increasing numbers of showers encroached from the east, and around 15th-17th the weather was more generally unsettled with a depression making its influence felt. Thereafter there was again a build of pressure, giving mostly fine weather, though fog affected parts of England and Wales, particularly in the south, while frontal systems affected north-west Scotland as the month approached its end. The last four days of the month were notably mild over much of England & Wales

The UK mean temperature was 9.8 °C, which is 0.3 °C above the 1981-2010 long-term average.Mean maximum temperatures were a little above average in the north-west, and mean minimum temperatures were a little above average in north-east England, Lincolnshire and Norfolk. It was a dry October with just 37% of average rainfall overall and the equal-fifth driest October in a series from 1910. However rainfall totals were closer to average in coastal parts of eastern Scotland, north-east England, Lincolnshire and Norfolk. Sunshine was mostly near average in the east and above average in the west, and it was exceptionally sunny in northern Scotland which recorded its sunniest October on record in a series from 1929. The UK as a whole had 114% of average sunshine.

The UK monthly extremes were as follows:  A maximum temperature of 22.2 °C was recorded at Trawscoed (Dyfed) on the 31st.  A minimum temperature of -5.0 °C was recorded at Tulloch Bridge (Highland) on the 25th.  In the 24 hours ending at 0900 GMT on the 14th, 49.8 mm of rain fell at Killylane (Antrim).  A wind gust of 56 knots (64 mph) was recorded at Sella Ness (Shetland) on the 28th.

Weather impacts

There were heavy showers and thunderstorms across much of England and Wales on the 1st.  Localised disruption was reported in Cambridgeshire, with flooding and two reported surface water related accidents on the A14. A lightning strike caused a property fire in Northants, and localised road flooding was reported between Thanet and Canterbury in Kent.     

There followed a long period of benign weather until mid-month, when on the 15th, rain over Perthshire, Angus and south Aberdeenshire caused the cancellation of a number of events due to flooding, and created surface water and difficult driving conditions on the roads. 

On the 24th, heavy showers and longer outbreaks of rain affected Cornwall, Devon and Somerset.  Devon & Somerset Fire and Rescue Service reported receiving more than thirty reports of flash flooding in the space of an hour, due to drainage systems not being able to cope with the volume of water. A few cars were stranded in flood water in Falmouth, and two women escaped after their vehicle became trapped in flood water. Diggers were brought in to clear mud from a roundabout on one of Cornwall’s main roads during the late afternoon. This caused serious traffic disruption between Falmouth and Penryn.    

From the 25th onwards, fog was a recurring issue, especially across southern England.  The fog slowed down road traffic in the affected areas and caused delays on ferries to/from the Isle of Wight. The main impact was on aviation, with delays and cancellations across many airports in southern and central England at times, including the London ones. This led to secondary impacts, with consequent disruption to air travel in other parts of the UK and Europe.

England Diary of Highlights

October began wet in the south with low pressure moving across the country, but an easterly type became established by the 3rd, and the rest of the month had mostly easterly winds, which brought showers into many eastern coastal areas, but plenty of sunshine for the west and especially the south-west.  The weather turned more unsettled between the 15th and 19th.  For most of the month temperatures were mostly near or a little below normal, but it was warm at the end of the month.
