Comments on November 2013
November temperatures were below average but it was only the coldest November since 2010. Rainfall was just a little below average. It was a much sunnier month than October, well above average. It was the 2nd equal sunniest November on record (with 1922) since 1882, beaten only in 1947.

Autumn temperatures were above average (+0.4°C), but not exceptionally so. Autumn was the 30th wettest on record since 1850.
