This picture taken at 1352 GMT on 5th August 2006 shows a part of the magnificent parterre at Wimpole Hall (10 km N of Royston). The view is from just outside the hall looking northwards across the parterre into the park and towards the lake and Folly, the latter being obscured by the large trees in the middle distance. The parterre extends to both the left and right of this photograph. It is a gorgeous summer day with a light north-westerly air with gusts to 6 knots, and a temperature of 26°C. The maximum temperature at Royston that day was 27.1°C, after an overnight minimum of 11.0°C, whilst the sunshine total was 11.8 hours.  The scene depicted in this photograph may look autumnal but the date is actually 11th August 2006 (at 0810 GMT). This boundary of trees and bushes between Burloes and Lowerfield E of Royston was a victim of a harvest fire on the hottest day of the year, 19th July, and has been badly scorched by the flames which destroyed some 40 acres of standing oilseed rape and barley crops. This view (looking southwards) is of the same belt of trees featured last month but in the reverse direction and shows that the burnt leaves have turned a much darker brown. Sunshine on this day was disappointing at 3.5 hours, as was the maximum temperature of 19.3°C. After the hot and sunny months of June and July 2006 the month of August was rather cool and unsettled  with rainfall well in excess of normal. However, on 30th August a ridge of high pressure crossing the country gave this fine display of early morning cirrus cloud over Royston (as viewed from close to the B1039 Royston to Barley road looking southwards) and this heralded a dry day with sunny spells and variable cloud ahead of a rain bearing warm front being propelled eastwards by a low in mid-Atlantic. The temperature at the time of the photograph (0801 GMT) was 14.5°C, whilst the sunshine total for the day was 10.1 hours.
