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, but after all’s said and done that only makes it the warmest since 2006, the warmest September in the series. More information on my blog.
