The already magnificent Wrest Park (27 km SSW of Royston) at Silsoe, Bedfordshire is currently undergoing restoration of its internationally important gardens including the Rose Garden, French Parterre and Italian Garden, all originally inspired by the great gardens of Versailles in France. In this picture (taken on 11th June 2011 at 1138 GMT) the new Rose Garden is in its infancy after having been recreated out of the previously grassed area. The beds have been planted with modern hybrid tea roses to recreate the effect of a late 19th Century rose garden. In the background in front of the House is the French Parterre, whilst to the left of the House adjacent to the conservatory is the Italian Garden which has been completely stripped ready for restoration. The state of the sky in the photograph indicates a day of fair weather and 8.8 hours sunshine was recorded at Royston and a maximum temperature of 19.3°C was achieved (30 Year average 18.5°C). The poppy border adds a splash of colour to this crop of peas adjacent to the B1039 Royston to Saffron Walden road some 2.5 km SE of Royston. This is an unusual crop for the Royston area and has had to contend with the record dry Spring in which only 28.4 millimetres rainfall was recorded in the months March to May inclusive, making it the driest Spring in the Royston rainfall record which commenced in 1853. The next driest Spring was in 1893 with 36.8 millimetres rainfall. Even so the peas look healthy enough and have no doubt benefitted from the increased rainfall in June but only time will tell how much the Spring drought has affected the ultimate yield. This view is looking northwards to Hyde Hill in the distance, the slightly different band of green in front of the line of trees being a crop of wheat. At this time (0815 GMT on 20th June 2011) the temperature is 15.2°C and a light SSW air of mean speed 1 knot gusting to 3 knots is drifting across the landscape. This South Cambridgeshire skyscape was viewed on 22nd June 2010 at 1306 GMT from the Barton Glebe Woodland Burial Ground (15 km N of Royston) which lies on the B1046 road between the villages of Barton and Comberton to the west of Cambridge. The area is under the influence of a shallow low pressure system centred to the east of Aberdeen and  being affected by the consequent showery airstream on its southern flank. A line of showers associated with an old occluded front has recently passed through and has been followed by well scattered showers, one of which is seen in the photograph tracking to the north of the burial ground. A planned feature of this developing woodland site is the extensive carpet of wild flowers which are in particular profusion at this time of the year. Despite the rain and showers on this day a sunshine total of 8.3 hours was  logged at Royston, whilst the maximum temperature for the day was 18.8°C (1.5°C below the 1981/2010 average).
