UK overview

Temperatures for June were above average across the UK, with warm days and mild nights, although there were no spells of exceptional warmth. It was rather unsettled early and late in the month, with localised thundery downpours on several days, but there was a period of fine anticyclonic weather around the middle of the month, bringing plenty of warm, dry, sunny weather.

The UK mean temperature was 14.2 °C, which is 1.2 °C above the 1981-2010 long-term average. This ranks as the equal-9th warmest June in a series since 1910. Rainfall was rather below average overall, particularly across the far south-east, north-west England and western Scotland, but slightly above average in parts of southern England and eastern Scotland. The UK overall received 75% of average rainfall. The UK received 105% of average sunshine hours, but the south and west fared much better than northern and eastern areas. Stornoway (Western Isles) recorded its warmest June in 140 years, whereas Lerwick (Shetland) had its lowest June sunshine total in an 82-year record.

A maximum temperature of 27.0 °C was recorded at Cupar (Fife) on the 18th. A minimum temperature of 0.7 °C was recorded at Llanarmon Dyffryn Ceiriog (Wrexham) on the 6th. In the 24 hours ending at 0900 GMT on the 5th, 56.0 mm of rain fell at Nunraw Abbey (East Lothian). Wind gusts of 50 mph were recorded at Warcop Range (Cumbria) on the 7th and at Sella Ness (Shetland) on the 18th.

Weather impacts

Heavy thundery downpours caused some localised flooding during both the early and latter parts of the month. Flash flooding affected the Nottingham area on the 9th, while on 13th to 14th lightning strikes caused disruption at Gatwick Airport and left several hundreds of homes without power in the Thames Valley.

In the last week there were again numerous instances of heavy showers and localised flooding, for example at Skegness on 24th when around 30 mm fell within around an hour, causing flash-flooding to several homes and businesses. The stages at Glastonbury Festival were temporarily closed on 27th due to lightning, and there were various other instances of lightning damage during the month, mainly across England and Wales south of a line from Anglesey to the Wash.

High pollen levels associated with the dry, warm weather in England and Wales around mid-month caused problems for hay-fever sufferers, with a surge in patient numbers visiting GPs.

England diary of highlights

The month opened with a few showery days, albeit quite warm with the exception of one generally cooler and wet day on the 4th; the showers often became heavier and more widespread around the 7th to the 10th. High pressure then built, bringing a spell of much more settled weather with some warm days and plenty of sunshine. The last week was more unsettled once more, with some local thundery downpours in many central and southern areas.

The mean temperature for the month was 1.0 °C above the 1981-2010 average. Rainfall overall was 75% of average but with a variable pattern. The north-west and south-east of England were notably dry, with parts of Cumbria, Lancashire, Suffolk, Essex and Kent receiving less than half their normal amount. Sunshine amounts were a little below average across some northern counties, but well above across the south and south-west with over 130% of average in some places. England overall received 112% of average sunshine hours.
