Comments on November 2004
November was another warm month, the 14th warmest November since 1850, although last year and 2001 were both warmer. Most remarkably, it was a very dry month, only 14.4mm, the second lowest November total on record since 1852. Nonetheless, there was a little less sunshine than normal, and the cumulative total for the year remains well below average.
