September was most notable for the amount of cold nights. The record minimum was matched together with three further new entries into the top ten list of extremes back to 1959 – a rare occurrence.
The mean temperature finished 15.2C, 0.2C below average, ending a run of 5 months where the mean has been, at times, well above average.
Some 32.6mm of rainfall was recorded, 63 per cent of the 1981-2010 average. Some 183 hours of sunshine were recorded, 132 per cent of average and more than August!
For the first time in years the autumnal equinox period was very stormy, as shown by this graph.
