You may have thought it’s been quite a warm start to June, but it pales into insignificance when you look back at the Central England Temperatures [CET] for the first eight days of June over the last 244 years. So far the mean anomaly for the first eight days of June 2016 has been +2.15°C above average, making it the 32nd warmest start since 1772. The warmest first eight days of June occurred in 1982 when the mean anomaly was +5.68°C, over three degrees higher. I suppose we can console ourselves that 1976 had a cooler start than 2016 has had, but then again there looks like there is a distinct change of type in the offing if the NWP models are anything to go by.
Interestingly there has been a very, very slight cooling trend for the mean temperature for the first eight days of June in the last 244 years.
