In the adjacent (Nene) river catchment to the Great Ouse catchment in which Royston lies this was the scene at Orton Staunch, Peterborough (65 km NNW of Royston) on 3rd March 2010 (at 1403 GMT). Although the first half of March was very dry with virtually no rainfall at Royston, the wet second half of February resulted in considerably raised river levels in the region. In this picture the normal waterfalls at this location have been submerged under the torrent with water being allowed free flow through the locks to reduce water levels upstream. This is the last but one set of locks before the sea and on this occasion downstream water levels are raised to flood proportions  as indicated here. On 5th March 2010 Royston experienced a colourful sunset which initially was confined to the horizon where the setting sun was capped with an array of  bright golden bands. Once these had dissipated and the sun had disappeared from view the dull red effect illustrated in this photograph (taken at 1751 GMT) spread upwards to illuminate the thin cloud covering this part of the celestial dome. The weather conditions at sunset on this day were wind strength 6 knots gusting to 10 knots (from WNW) and temperature 5.5°C (after a day maximum of 8.2°C). The day had been fairly sunny with a total sunshine of 6.6 hours being accumulated. This had been preceded by an overnight minimum temperature of -3.0°C.  If this horse (as photographed at Burloes, Royston on 15th March 2010 at 0949 GMT) is looking for new shoots of grass it will be unlucky as the weather has prevented the growth of any new season grass so far. With each of the three Winter months December to February experiencing below average temperatures the first half of March has been even colder relatively speaking with the mean temperature being over 3°C below normal! Milder conditions thereafter this month have belatedly stimulated the growth of grass in the district. The sunshine apparent in this picture lasted for much of the day and total sunshine of 7.1 hours was recorded. The temperature rose to a maximum of 14.1°C on this day after an overnight minimum of 3.7°C..
