Please pm your December prediction to me by midnight on 30th November.
Some background information:
The last cold December was in 2010 with an exceptional -0.7c. This followed 2009 with a cold 3.0c, the second coldest this century.
Since then every December has been above the 61-90 average of 4.5c ranging from 4.7c to 6.8c. The only exception was 2015 with a record 9.6c.
Last year the models were indicating a cold month at this stage only to perform an about turn and the month ended up mild at 6.3c.
The 30 year 91-20 average is 4.8c.
Not an easy choice.
