    July 2012 continued the recent run of unsettled Julys. It was exceptionally wet and sunless until the 20th, but the fourth week was warm and fine over England and Wales. Curiously, a similar sequence occurred in both March and May this year too. Although the month was memorably wet, perhaps even more remarkable was the lack of sunshine, especially in Scotland where a new record for low July sunshine was set.

    Temperatures

    July was cool overall, but there have been 29 cooler Julys in the last 100 years. Mean maximum temperatures ranged from 21.6C at St James's Park, London, to 12.9C at Fair Isle (Northern Isles). Daytime temperatures were typically 1.0-2.5C below average. The Central England Temperature of 15.5C was 1.2C below the mean for 1981-2010. The highest maximum temperature was 30.7C at St James's Park, London, on the afternoon of the 25th. The lowest was 10.3C at Aviemore, Inverness-shire, on the 7th. The minimum temperature recorded was 0.8C at Tulloch Bridge, Lochaber, during the night of the 30th/31st. On the warmest night of the month, temperatures fell no lower than 18.6C on the 26th/27th at Jersey airport.

    Rainfall

    Rainfall over England and Wales during July was 109mm, 165% of the average for 1981-2010. In the last 100 years just 12 Julys were wetter while 88 were drier. The equivalent figures for Scotland were 97mm (136% of the normal amount) and for Northern Ireland 77mm (109%). For the second month in a row, the far north of Scotland was unusually dry. Monthly totals varied between 201mm at Spadeadam Forest, Cumbria, and 35mm at Kirkwall, Orkney.

    Sunshine

    Sunshine averaged over England and Wales during July was 165 hours (82% of the 1981-2010 mean), making this the dullest July (equalling 2010) since 1998. Scotland averaged just 99 hours (61% of average) and Northern Ireland averaged 135 hours (83%). The largest total in the UK was 209 hours at Guernsey airport, but the smallest was a new UK record low for July of just 48 hours at Eskdalemuir, Dumfries and Galloway. Other low totals included a mere 60 hours at Aberdeen.
