The averaging period used for the following assessment was 1971-2000.
For most of the month, rain-bearing Atlantic weather systems were absent and pressure was relatively high. This meant that June saw plenty of dry, sunny weather, especially in the second half when it became very warm over England. Any widespread rainfall was largely confined to the second week. The weather also turned unsettled from the west and north towards the end of the month, with the warm, fine spell becoming confined to eastern England. Mean temperatures were above average in all areas, ranging from about 1 °C above close to the east coast to about 2 °C above over Northern Ireland and western Scotland. Daytime maximum temperatures were well above normal, by about 2.5 °C in many western and central areas. June saw below average rainfall across almost the whole UK, with less than 50% of normal in many areas including much of Scotland, south Wales, north-west England and southern England. Sunshine totals ranged from about 20% below normal across much of northern Scotland to about 50% above in south Wales and south-west England, where June was the third-sunniest in a series from 1929.
A maximum temperature of 30.9 °C was recorded at Gravesend (Kent) on 27th. A minimum temperature of -0.1 °C was recorded at Cromdale (Highland) early on 15th and at Carterhouse (Borders) early on 20th. In the 24 hours ending at 0900 on 29th, 64.6 mm of rainfall was recorded at Cwmystradllyn, near Porthmadog (Gwynnedd). A wind gust of 51 m.p.h. was recorded on 28th at Capel Curig (Conwy).
High pressure brought a good deal of dry, settled weather through the month, with a more changeable interlude in the second week. Daytime temperatures were generally close to or above normal, especially in the last 10 days when it became very warm in eastern areas. There were some cold nights around mid-month. Mean temperatures were above average in all areas, typically by about 1.5 °C, and daytime maximum temperatures were well above normal, by about 2.5 °C in many parts of the Midlands and central southern England. June saw below-average rainfall across almost all areas, with less than 50% of normal close to the Scottish border, in Lancashire and across parts of the south. It was sunnier than normal almost everywhere, and especially so across the south-west where more than 140% of average was recorded. It was the sunniest June over England since 1996.
1st to 5th:
Rain spread eastwards on 1st but after that high pressure dominated with warm, dry and fairly sunny conditions for many places. Mornings generally saw some mist and fog. There were a few showers in northern England on 4th and 5th, some with thunder in Yorkshire on 5th. It became increasingly warm, with the temperature reaching 28.0 °C at Heathrow (Greater London) on 5th.
6th to 13th:
A more unsettled period with showers or rain on most days. Between 6th and 9th, showers were often heavy and thundery, with some significant totals, for example 29.6 mm at Marham (Norfolk) on 6th and 21.8 mm at Bramham (West Yorkshire) on 7th. Heavy rain moved into southern areas on 10th and continued in the south-east into 11th, giving a total of 44.0 mm at Manston (Kent) and 20-30 mm widely in Sussex and Kent in 24-hours to 0900. The 12th was a drier interlude, before further heavy showers spread across southern counties during 13th. Temperatures were generally around normal, but easterly or north-easterly winds made it rather cool in the east at times.
14th to 17th:
High pressure returned to give a largely dry few days with a good deal of sunshine, though a few showers remained in southern areas on 14th. Daytime temperatures were warm for the most part but the nights were cold, with minima early on 17th of 1.9 °C at Exeter (Devon) and 4.3 °C at Benson (Oxfordshire). South-east England experienced brisk north-easterly winds for much of the period but winds were mainly light elsewhere.
18th to 20th:
A band of rain moved southwards on 18th, becoming heavy and slow-moving in the West Midlands during the afternoon, with 20 mm recorded at Shobdon (Herefordshire). Strong northerly winds brought cloud and showers to eastern England on 19th, with a gust of 50 m.p.h. at Donna Nook (Lincolnshire). Otherwise, it was mainly dry and clear but still cold overnight, with a minimum temperature of 0.2 °C at Shap (Cumbria) early on 20th.
21st to 27th:
Another settled period with high pressure dominating. Most places stayed dry with plenty of sunshine and it was warm or very warm, especially across the Midlands and eastern England, where the temperature exceeded 25 °C widely each day from 22nd. The highest temperature of the year so far, 30.9 °C, was recorded at Gravesend (Kent) on 27th. Nights also became increasingly warm, with minimum temperatures around 15 °C in parts of the south-east by 26th. There were some thunderstorms over the Pennines and the north-east on 26th.
28th to 30th:
More unsettled in south-western and northern areas, with some rain on 28th becoming heavy and thundery in the north on 29th. There were also some showers across eastern and southern areas on 29th. A generally dry day on 30th. The very warm theme continued, especially in the Midlands, East Anglia and the south-east. Overnight minimum temperatures continued to rise, with St James's Park (Greater London) recording 17.8 °C early on 30th.
A largely dry and fine month, but with a few showery days. Some warm weather but there were cold nights around mid-month. Mean temperatures were above normal, by 1.3 °C to 1.5 °C, due partly to some warm days resulting in daytime maximum temperatures up to 2.5 °C above normal. June was a dry month in all areas, with less than 50% of average rainfall across most of south Wales. It was a sunny month, with totals about 40% above normal, making it the sunniest June since 1975.
