The averaging period used for the following assessment was 1981-2010.
The first part of June was largely unsettled, bringing significant amounts of rainfall to most areas. England and Wales became more settled after the 10th, with a build in pressure, though rain-bearing fronts continued to steer round the northern edge of the high pressure with western Scotland remaining wet at times. Very warm air was drawn up from the south from the 16th onwards, and every day from 17th to 21st somewhere in the UK exceeded 30 °C. The highest value recorded during this spell was 34.5 °C, at Heathrow Airport on the 21st, and this was the UK's highest temperature reading in June since 1976. Fresher air moved in over the whole UK within the following two days, and low pressure became established for the last four days of the month bringing plenty of rain in many areas.
The provisional UK mean temperature was 14.5 °C, which is 1.5 °C above the 1981-2010 long-term average, making it the equal fifth warmest June in a series from 1910. Temperatures were highest relative to normal in eastern counties of England. Rainfall was well above normal over large parts of the country, with up to three times the average amount in parts of southern and eastern Scotland, though a few places in the English Midlands and the Outer Hebrides came in just below average. The UK overall had provisionally its sixth wettest June in a series since 1910, and for Scotland it was the wettest June in that period. Sunshine was above average in south-east England, but below average in northern and western areas of the UK.
The UK monthly extremes were as follows: A maximum temperature of 34.5 °C was recorded at Heathrow (Greater London) on the 21st. A minimum temperature of -2.3 °C was recorded at Altnaharra (Sutherland) on the 8th. In the 24 hours ending at 0900 GMT on the 7th, 112.4 mm of rain fell at Torwinny (Moray). A wind gust of 60 knots (69 mph) was recorded at Inverbervie (Kincardineshire) on the 7th.
Most of the weather impacts worthy of note this month centred around heavy rainfall, some of it thundery in nature. Thundery downpours during the afternoon and evening of the 2nd across East Anglia, London and parts of SE England caused localised flooding, with some disruption to trains, roads, and at Stansted Airport.
Persistent rain fell across much of the country on the 5th/6th, together with some unseasonably strong winds across England and Wales. Tragically, on the 6th three men died in Plymouth when their van overturned, and there were two deaths due to trees falling on cars, one in Hampshire and the other in Perthshire. Over 300 homes and businesses in Devon and Cornwall lost power, and fallen trees were reported across a wide area, bringing down overhead power lines, while floods also blocked some major roads. Localised flooding also affected eastern Scotland, including Edinburgh’s trams and the Inverness to Aberdeen rail line.
The 17th was the start of several days of notably hot weather across England and Wales, with maxima exceeding 30 °C somewhere for 5 consecutive days – the first time this has happened in June since 1995. Impacts from the hot weather sadly included a further two fatalities, with two teenage boys drowning in separate reservoir incidents in Rochdale and Walsall. The heat also affected train services in south Wales, and over 90 trains were cancelled or disrupted across Norfolk, Suffolk and Essex. A road bridge in Lowestoft, Suffolk became stuck after the mechanism seized due to high temperatures, and roads in Cambridgeshire and Norfolk reportedly started to melt.
On the 21st there was a risk of large hail, frequent lightning and gusty winds. Localised flooding was reported in north-east England and lightning strikes were reported across northern England. On the 22nd, roofs were damaged by lightning in Kent, North London and Leicestershire, power cuts were reported across Kent, while Thameslink, Southern and Greater Anglia train services were all affected by lightning strikes.
On the 27th, lightning strikes caused more rail disruption between East Anglia, Essex and London. Localised flooding was also reported on roads in the south-east. More persistent rain and strong winds across southern and eastern England on the 28th led to minor disruption to road, ferry and rail travel.
