| Preparatory work for the new rail underpass linking Coombes Hole with Burns Road in the northern part of Royston has continued apace through the month of August, this being the scene looking north-westwards along Coombes Hole towards the railway line on 5th August 2011 at 1101 GMT. Part of the Green Street allotment site has been taken over temporarily to facilitate construction of the underpass and in the left foreground of this picture is the heap of topsoil which has been removed for the duration of the work, and now awaits completion of the project before being reinstated to its former location. Temporary fencing has been installed along Coombes Hole (as shown) to shield the adjacent housing area. The weather conditions at this time consisted of a westerly breeze of mean speed 2 knots gusting to 7 knots in a temperature of 20.5°C. Although sunny at this time the total sunshine for the day was only 4.9 hours, but the temperature peaked at a slightly (+0.8°C) above average 24.5°C. | The Town Hall roundabout to the east of Royston Town Centre has featured in these pages several times previously showing the flower displays which are virtually an all year round attraction. Summer 2011 has been no exception and here the roundabout is viewed from its southern side at 1535 GMT on 19th August 2011. Melbourn Street and the Town Hall itself are westwards to the immediate left, whilst Newmarket Road runs off eastwards to the right and Melbourn Road northwards through the trees at the top left of the picture. A famous Royston landmark used to be the Priory cinema on a prominent site bordering the roundabout to the right, but this was demolished in the last decade, having previously being destroyed by fire in 1933 and later rebuilt. At the time this picture was taken the temperature was 20.7°C, relative humidity 56%, wind direction SW, and mean wind speed 7 knots gusting to 12 knots. The day was the sunniest of the month to date with sunshine of 11.5 hours. | 0n 25th August 2011 a little early morning rain in Royston was followed by a brief brighter interlude before a further area of rain moved in from the south-west giving mainly light rain for a 2 hour period from approximately 0900 to 1100 GMT. In this picture the cloud responsible for this rainfall is seen approaching Royston at 0823 GMT and looks rather more ominous than the subsequent precipitation it actually produced. The terrain featured in the picture is farmland on the Burloes estate on the eastern side of the town, the crop of oats in this field having been harvested earlier in the month. Just visible to the left of the resultant stubble is an area of sugar beet on land bordered by the Barkway Road, Barley Road and Cow Plantation. The temperature is a rather cool 13.0°C in a SSW wind of mean speed 8 knots gusting to 13 knots. The temperature later rose to a maximum of 19.8°C which is 1.6°C below the 30 Year (1981/2010) average maximum for this day. |
