I'll go for a good mixture of 1997 and 2007...
January: Very cold but settled and sunny start, then turning and remaining mild and wet after the first week or so, with a gale-storm towards the end of the month.
February: Turning colder at the start of the month again, but remaining unsettled with heavy snow over a couple of days, the heaviest falls since January 2010 and similar to the February 2007 and 2009 snowfalls. Very mild, dry and dull second half of the month.
March: Dry, dull and warm conditions continue for the first couple of weeks, the sun then breaks to give an incredibly sunny third week before a return to cloudier weather for the final week. Dry and mild throughout. (Again similar to 2007 and 2009).
April: An intense warm front from the south continues the theme of dry weather and brings with it an incredible two-week heatwave over the middle two weeks, coinciding with Easter. Unbroken sunshine and record-smashing temperatures, the average breaking 11 degrees and a high of 32 degrees being recorded in London. Turning cooler but remaining dry and sunny in the last week. Puts 2007 and 2011 in the shade.
May: A dry, warm and sunny first week signals the end of the settled weather as Atlantic fronts break the high from then on. Very wet and dull for the remainder of the month.
June: A brief high in the first week bridges the Atlantic systems, making for a very warm and dry first week. Turning increasingly humid with thunderstorms preceding a very wet remainder of the month. Not quite as wet as 97 and 07 but in a similar region. Temperatures around average.
July: Wet, cloudy and cool with Atlantic weather dominating. A warm front in the final few days brings a hot and dry end of the month and a change in the theme of the summer.
August: The warm weather continues at the start of the month with the hottest temperature of the summer being recoded on the 5th (30.5 C), but not breaking the April high.. Convections then begin to dominate after the hot first week, making for a very humid, warm, wet and thundery remainder.
September: Settling down, fairly close to average temperatures and fairly dry throughout. Reasonably sunny.
October: Very much a continuation from September; fairly dry and mild, but with some night frosts in the final week. Average sunshine.
November: Dry, mild and fairly dull (like 2007)
December: Another mild one, but turning wetter in the first two weeks. A cooler and very foggy third week (aka 2006) before another Christmas Eve gale-storm brings about a very wild and damp Christmas period, with a big thunderstorm on New Years Eve to see in the new year.
