| From a vantage point close to Eagle Tavern 1.5 km SE of Royston this is the view southwards to the crest of the East Anglian Heights on the horizon at 0824 GMT on 1st September 2006. The sky looks somewhat threatening to the SE, but the intermittent rainfall which occurred in the 3 hours to 0730 GMT has now stopped and a dry day ensued. The photographer is facing a S wind of mean speed 2 knots gusting to 14 knots in a temperature of 16.3°C. The temperature later achieved a maximum of 22.7°C, whilst sunshine for the day was 5.5 hours. The former Eagle Tavern P. H. can just be seen near the right hand margin of the picture. | Another fine display of cirrus cloud occurred over Royston in the morning of 20th September 2006, this view from the Burloes estate to the SE of the town being seen at 0810 GMT. This cloud advanced ahead of a depression to the west of the British Isles but unusually instead of continuing its eastward movement it retreated westwards during the day to leave sunny skies over Royston. The trailing cold front of this low pressure system was latched on to by ex hurricane 'Gordon' then positioned to the west of the Iberian peninsula, and this combination was then responsible for bringing rainfall to Royston some 48 hours later. | Once again travellers on the A10 London to Kings Lynn road through the town of Royston this Summer have witnessed a fine display of flowers on the Town Hall roundabout. This is the view looking westwards (at 0902 GMT on 21st September 2006) towards Melbourn Street from a point adjacent to the now demolished old cinema which used to (along with the Town Hall) provide an imposing reference point by this junction. Part of the Town Hall itself is seen behind the roundabout. On this day the temperature achieved its highest value (27.5°C) for 21st September since at least 1972, the previous highest temperature for this date being 25.8°C in 1989. |
