A distance of 17 km ESE of Royston this is one of England's grandest stately homes, Audley End House, near Saffron Walden. Originally the site of a Benedictine monastery (Walden Abbey), the present house is largely an early 17th century country house built primarily for entertaining royalty (King James I) and has been much modified over the years. The present house includes a Victorian service wing containing a kitchen, laundries and dairy. Live demonstrations are occasionally given in these facilities, whilst at other times visitors can experience an impression of the duties of  the staff in Victorian times through video projections on the walls with accompanying sound. In this view as seen at 1055 GMT on 7th June 2013 the eastern elevation is featured together with the formal gardens (the Parterre) and part of the parkland which rises up to the Temple of Concord. The parkland in the foreground is the site of open air concerts, which have attracted many well known artists, the gently rising ground making an excellent venue for spectators. On a meteorological note the residents of the House would never have been in any doubt as to the wind direction as the roof has no less than eight gold coloured wind vanes! The photograph indicates a fair early Summer's day and at Royston a maximum temperature of 22.6°C and sunshine of 13.7 hours were recorded. Just as the colour intensity of the oil seed rape starts to wane, along comes the mustard! This photograph was taken on the Burloes estate, Royston at 0813 GMT on 15th June 2013 and shows a large acreage of mustard in the foreground whilst beyond the hedge in the middle distance is part of an equally large area of oil seed rape. Just 5 weeks previously the mustard was only at seedling stage and in the short ensuing period has rapidly grown to a height of 1.5 metres and burst in to flower. Although the oil seed rape is exhibiting a solid display of colour at this time it is, in fact, just past its maximum flowering and within 10 days the seed pods had taken over and the colour all but disappeared. Two further fields of mustard are growing nearby giving the estate a spectacular veneer. The temperature at this time was 12.5°C, later rising to a maximum of 17.6°C, not a particularly impressive value given that it was 3.0°C below the 30 Year (1981/2010) average maximum temperature for 15th June. The preceding night minimum temperature of 10.3°C was actually 0.5°C above the 30 Year average, however. The build up of early morning cloud as illustrated in the picture did not prevent a sunshine accumulation for the day of 9.1 hours, compared with an average of about 6 hours for a June day. Only 22.4 hours sunshine had been recorded in the previous 7 days. As the A505 and B1039 roads diverge from Royston in ENE and SE directions respectively large tracts of arable land are encompassed within their boundaries. In this picture taken at 0803 GMT on 25th June 2013 from the B1039 road about 2.5 km SE of Royston one such large area of arable land under cultivation is featured. The soil in this field appears very dry as a result of the very dry June to date and the sugar beet seedlings in view have been struggling against these adverse conditions, whilst the green band in the middle distance indicates slightly less dry conditions giving larger plant sizes in this area. In any event the crop got off to a rather slow start due to the coldest Spring since records began at Royston (Iceni) Weather Station in 1972. Rainfall in June to 25th was only 12.7 millimetres, which is only one-third of the 30 Year (1981/2010) average for this period. A WNW breeze of 4 knots gusting to 7 knots is drifting across the landscape at this time in a temperature of 13.2°C. The temperature later rose to a maximum of 20.8°C after an overnight minimum of 7.6°C. Sunshine for the day was 9.9 hours. After a first week of June which yielded an exceptionally high sunshine total of 77.6 hours, sunshine subsequently had been at a premium and 25th was one of the few sunny days since then as the cumulative sunshine total for the month gradually drifted below average.
