| This is the north-western end of the Barkway Road as it joins the A10 one-way system (southbound) in downtown Royston. On Priory Lane off to the right is the old Police Station and the Priory Memorial Gardens whilst straight ahead is the market area and the southern ends of the High Street and King Street. The picture was taken on 16th October 2010 (at 0844 GMT) with a dash of Autumn colour and early leaf fall in evidence. The temperature at this time was 7.9°C, later rising to a maximum of 13.0°C (1.1°C below the 30 Year (1976/2005) average for this day). The wind direction is NNW, and the mean wind speed is 5 knots, gusting to 14 knots. Sunshine for the day was 5.6 hours. | On 21st October 2010 when this photograph was taken high pressure covered the southern half of the British Isles, gradually migrating eastwards into Europe. The morning on this date saw a fine display of cirrus cloud (plus some aircraft contrails) over Royston and this view (at 0738 GMT) is looking north-eastwards from a point near to the A505 road 2.5 km E of the town. A fresh SW breeze of mean speed 9 knots gusting to 15 knots is sweeping across this very open area in a temperature of 3.9°C. The early morning sunshine (7.2 hours for the day) is illuminating the shiny leaves of this crop of sugar beet, which will soon be due for harvesting and transporting to a processing plant, the sugar campaign having already started. | The first air frost of the season at Royston (Iceni) Weather Station occurred on 25th October 2010, even though it was a somewhat marginal situation with the minimum temperature only being 0.1°C below zero. However, lower parts of Royston and areas to the north on the South Cambridgeshire Plain may have experienced a lower minimum temperature. This day had the benefit of unbroken sunshine and the sunshine total of 9.1 hours makes it a likely candidate for being the sunniest day in October this year. On this date the University Botanic Garden in Cambridge (21 km NE of Royston) was a blaze of colour in the bright sunshine, this tree (as photographed at 1032 GMT) near to the Hills Road entrance being just one such example. |
