The town of Stevenage, some 20 km SSW of Royston, has a high proportion of tree species which regularly give a fine display of colour in the Autumn of each year. This Autumn  is no exception and Fairlands Valley Park (in which this picture was taken at 1141 GMT on 17th October 2003) is particularly resplendent this year. Also noteworthy is the condition of the grass  for mid-October, having ceased to grow and very parched in appearance after the long dry spell. The abundant sunshine which has accentuated the effects of the drought continues on this day, totalling 9.3 hours for the day at Royston. A familiar landmark in the Royston area, this is the 18th Century Gothic Tower at the Folly on the Wimpole Hall Estate some 10 km N of Royston. The severe drought which commenced on 2nd August in an already dry year has still not been alleviated by any appreciable rainfall at the time this photograph was taken on 27th October 2003 (at 1147 GMT). The field grass is looking very dry and the lake in the valley below the Folly is well below its normal level. The 27th was yet another sunny day (9.1 hours at Royston) but the maximum temperature achieved was 2.0°C below the 30 Year mean for 27th at 11.5°C. Another example of grass suffering badly from the current very dry weather! Autumn colours enhance the scene in this view of Priory Gardens, Royston at 1010 GMT on 30th October 2003. The east face of the 12th Century Parish Church is illuminated by the morning sunshine which was continuous until 1400 GMT, when advancing cloud (and later rain!) from the south-west resulted in a dull end to daylight hours. The current temperature is 6.5°C, later reaching a maximum of 10.2°C at 1225 GMT. The wind is from the  SW, mean speed 2 knots gusting to 8 knots. Total sunshine for the day was 6.4 hours.
