On Sunday, 10th August 2008 the Royston Allotments & Gardens Association held its 3rd Annual Open Day. Here a plot holder is displaying his prize winning marrow for a local news photographer, whilst some of the entries in the Dutch Tray competition are also visible. A further competition, for the best scarecrow, attracted a wide range of original entries which were displayed and judged on the individual plots. The Open Day enjoyed fine weather, albeit rather windy but fairly sunny. When the photograph was taken (at 1105 GMT) a westerly wind of mean speed 14 knots gusting to 30 knots was sweeping across the allotments, in a temperature of 19.9°C. Sunshine for the day was 10.5 hours. This is the view southwards from the Hertfordshire Way (on 17th August 2008 at 0757 GMT) as it crosses the ridge just beyond the southern boundary of the town of Royston, a short distance to the east of Flint Hall Farm.  The Hertfordshire Way itself is the green strip on the right of the photograph as it descends towards Grange Farm and  more level ground before ascending the East Anglian Heights beyond Hatchpen. The field of oats in the foreground has just been harvested (the previous day), but is now rather wet after early morning rain. However, the cloud is clearing and sunshine commenced at 0845 GMT, accumulating 6.3 hours for the day. The temperature is 14.9°C, later rising to a maximum of 21.7°C. The third picture this month (at 1327 GMT on 23rd August 2008) is remote from Royston, and depicts the Ickworth Vineyard some 50 km to the ENE at Horringer, Suffolk. This is the western boundary of the vineyard which is situated in the Walled Garden at Ickworth Park, several hundred metres from Ickworth House. The vineyard slopes SSW to The First Earl's Summer House where the beauty of the canal views can be appreciated. The varieties of grapes from the vineyard are made into the award winning Ickworth wines. The mostly cloudy afternoon on this day was typical of this year's August sunshine regime which at Royston was running at only 70% of the daily average up to this point in the month.
