September 2016 ended up the fifth warmest in the central England temperature [CET] series that began in 1659. I reckon the mean temperature for the month was 16.05°C, and the anomaly +2.53°C above the 1961-1990 long-term average. It never quite matched 2006 and almost caught 1949, and after all’s said and done that only makes it the warmest since 2006, the warmest September in the series.
Both maximum and minimum temperatures were almost always above average for the entire month, with no real cold spell in evidence. Two new CET maximum records were set on the very warm spell on the 13th and 14th, and a new high minimum was also set on the 14th as well.
