"July saw the largely settled, static weather patterns of spring and early summer replaced by a more changeable Atlantic type. This airstream was relatively warm but often cloudy. Whilst the north-western half of the UK saw more rainfall than in recent months, the south-eastern half remained drier than average with many warm days. There was a west-east gradient in mean temperature, ranging from close to average in much of Scotland, Northern Ireland, Wales and western England to over 2.0 °C above average in East Anglia. July saw over twice the normal rainfall in a broad swathe from west Wales through north-west England, southern and eastern Scotland to Shetland. It was also wetter than normal across most of the rest of Scotland and Wales, and in Northern Ireland. In sharp contrast, much of the Midlands, eastern and southern England were very dry with less than half the normal amount in counties from Cambridgeshire to Sussex. Overall, it was duller than average, especially in many western areas. The only places with more sunshine than normal were those towards the east coast and in the Northern Isles."
