It was dry and sunny in the west, cooler and cloudier in the east, and wet in some easterly districts. Temperatures were in fact slighly below normal; the CET was the lowest since 1994. There were no "warm days" above 24C: the first time this has happened since 1995. Unusually, it was relatively dry in the west and wet in the east. Some places in northern Scotland had their dullest September on record. An anticyclone centred to the west of the British Isles gave NW winds, leading to the coldest first half of September since 1994. First signs of autumn on the 4th with low temperatures (2C at Saughall, near Glasgow), and 3C in East Anglia n the morning of the 5th; widespread ground frosts. The 6th was the first day since June 18th when 21C was not breeched anywhere in Britain. The 7th saw the first gale of the autumn across southern Scotland and northern Britain. On the 9th and 10th the maximum at Cromer was only 13C, and no more than 11C at Buxton on the 13th. After the 18th, the winds switched from the NW to the NE until the 26th. Hence in the third week, it was cool, dull, and wet in the SE, and sunny and warm in the NW: 22C at Loch Sloy (Argyll) on the 19th, but 11.7C at Whipsnade on the 17th. The 28th was a very warm day in the south: 24C at Northolt in London, and 22C as far north as York, with unbroken susnhine (although it was grim up north). Gales on the 30th.
