Ground frosts can be expected on 2 nights in each June but occurred on 8 mornings in the June months of 1972 and 1996.

The monthly mean rainfall for June in Reading is about 45 mm with falls in individual months ranging from 155 mm in 1971 to 0.5 mm in 1925. June 1971 was a cool and wet month - the only June on record to surpass a total of 150 mm; 10 mm or more fell on four days with 54.7 mm falling on the 10th during a spell of almost 21 hours of rain that day. June 1925 was the only dry month from April to October that year - all the measurable rain fell on the 26th. The wettest June day saw 60.5 mm falling on 11 June 1970 (a thundery day with just 2.3 hours of rainfall; hail as large as peas fell at one point and there was flooding on and close to the University campus in the afternoon).

The average sunshine duration in June is about 189 hours - very similar to May and only slightly less than in July and August. The sunniest June was that of 1975 when 306 h of sunshine occurred - while 1990 (109 h) and 1991 (110 h) were the dullest Junes in the University record. June 1975 was the sunniest of any month in the Reading record and the only one to exceed a total of 300 h. Sunny days in June can record over 15 hours of sunshine - at Whiteknights there were 14 such days during 1968-2014. On 30 June 1976 16.0 h of sunshine occurred on the 30th.

Snow has never been recorded in June in Reading. On average thunder is heard on 12 days in June every 10 years although June is thunder-free in about 3 years in every 10 on average. Fog is very rarely seen in June at 0900 GMT - the early sunrise means that any early fog has time to evaporate and disperse by this time. In fact, only 24 June 1908, 2 June 1999 and 30 June 2000 had fog at this time in Reading's June record.
