England and Wales diary of highlights

Fairly settled and warm for the first two weeks, but turning much cooler with spells of wet and windy weather from the 17th onwards.

1st to 6th A weak ridge of high pressure built across Wales and south-west England for the first week of the month, keeping these areas mostly dry, but weak fronts pushed down the North Sea to give some light rain at times over eastern counties of England.

7th to 16th By the 7th the high pressure had drifted into central Europe allowing warm air to spill in from the Continent, as well as allowing a few thunderstorms to develop. The hottest day occurred on the 8th when several places in southern and eastern England reported over 30 °C, the highest being Cambridge with 31.5 °C. During the evening scattered thunderstorm occurred, with Leconfield recording 12.6 mm of rain. The high pressure maintained its influence until the 16th keeping many places dry and warm but scattered showers did occur in places. Temperatures reached 29 °C in Bournemouth on the 15th and 27 °C in Leicester on the 16th.

17th to 21st On the 17th a cold front crossed the area bringing a change to much fresher weather with blustery west to north-westerly winds. On the 18th Scarborough and Leeds saw maximum temperatures of only 10 °C, and a frost was recorded at Shap Fell overnight as temperatures fell to -0.2 °C. The cool north to north-westerly airflow continued until the 21st.

22nd to 24th The main event of the month occurred on the 22nd and 23rd as a major depression swept across Wales and northern England. The central pressure at 0600 on the 23rd was 982 hPa, making it one of the deepest depressions recorded in June over England and Wales. Many parts of Cornwall, Wales and Cumbria received over 25 mm of rain, Dunkeswell recording 34 mm of which 22.1 mm fell in just 2 hours. On the 23rd gales force winds along the English Channel coast gave gusts in excess of 50 knots, Dover reporting 58 knots. The low pushed out over the North Sea on the 24th but not before giving 47 mm of rain at Loftus and gusts of 40 to 50 knots over eastern England.

25th to 27th The next depression on the 26th gave 22.8 mm of rain at Plymouth and as it cleared on the 27th, heavy showers and thunderstorms broke out in its wake.

28th to 30th Southern areas stayed mainly fine and dry but showers affected the north and west. Some heavy showers occurred over northern England on the 30th with totals of 7 mm in one hour at Manchester and Preston.

Scotland diary of highlights

Dull and wet.

Unsettled conditions prevailed throughout June, leading to a dull and wet month in most places. At Kinloss some heavy showers made it the wettest June since records began in 1951. A northerly spell in the second half of the month failed to prevent the temperature from being above average.

The first four days were changeable westerly and characterised the month as a whole. Rain from fronts on the 1st was followed by a ridge giving a fine day on the 2nd. The 3rd and 4th were rather cloudy with some sun and a few showers.

High pressure near the English Channel directed a warm and humid air mass across Scotland on the 5th, with the cloud breaking in Grampian region but producing drizzle in the north-west Highlands. During the next couple of days a cold front introduced cooler and less humid air, giving dry weather with sunny intervals in most places.

Low pressure in mid-Atlantic moved slowly towards Shetland from the 8th to the 11th, giving unsettled and showery conditions. There was 33 mm of rain at Dalmally on the 10th and 38 mm at Tain the next day.

High pressure developed to the south of Ireland on the 12th and gave a fine day over most of Scotland. On the 13th and 14th a warm and humid westerly airstream blew across Scotland, bringing cloud to most places. There was drizzle in the north-west Highlands but the cloud broke in the east and on the 14th the temperature at Aberdeen rose from 17 °C to 26 °C.

A spell of northerly winds with cool and showery weather lasted from the 15th to the 22nd. There was more general rain on the 16th and 19th and on the latter day the maximum temperature was 9 °C at Aviemore and a few other stations. On the 22nd there were only a few showers and the temperature fell to 2 °C at Dalmally and Tulloch Bridge.

On the 23rd a major depression moved north-east across England and its fronts gave a thoroughly wet day over most of Scotland with 47 mm of rain at Glenlivet. It was windy in the central belt with gusts of 52 knots at Shotts. The rain cleared slowly to the east on the 24th but another frontal system brought more rain and wind on the 26th. At South Uist gusts reached 60 m.p.h.. Between these weather systems a ridge of high pressure gave a sunny day on the 25th.

Low pressure in mid-Atlantic gave south-westerly winds over Scotland from the 27th. The weather was mostly showery with 42 mm of rain at Kinloss on the 27th.
