It was a very anticyclonic month so with high pressure close by we had plenty of dry days. Interestingly nearly all the months rainfall fell on two successive wet Tuesdays - 9th and 16th.

November continued on the anticyclonic theme and was another month when most places had below average rainfall. The high pressure was centred to the west at times during the month and this caused winds to come from the northwest bringing showers to north and east Norfolk, this was the wettest area in our region with rainfall totals 50-70mm which is around average for November. The rest of Norfolk and Suffolk had rainfall totals of 25-50mm. Howe was the wettest place with 73.5mm, Alby had 52mm and Pakenham had 33mm.

Here in Calthorpe my rainfall total was 65.5mm, 87% of average and was the driest November since 2004. The wettest day was the 13th when frequent showers with hail came in from the North Sea giving me a total of 21.6mm. Temperatures were about average for November with a mean of 7.3°C. My sunshine total was 50.8 hours, only 66% of my average.

The autumn (Sep, Oct, Nov) was drier than average across the region and was the driest since 1997 or 1989 for some places. It was the anticyclonic conditions which prevailed throughout the autumn what made it drier than average, a much welcomed relief after the very wet summer.
