| There was a brief warm spell around 9 September, on which date the highest September temperature for six years was recorded, but much of the rest of the month was cool. In fact it was the coolest September since 1993, and heavy rain during the third week caused floods. This was the result of a deep and slow-moving low pressure system delivering copious rain between 23 and 25 September. Prior to that it was dry in East Anglia and south-east England. | There was a brief warm spell around 9 September, on which date the highest September temperature for six years was recorded, but much of the rest of the month was cool.
