I find this thread incredibly interesting because at Bablake we have
statistics averaged for every day of the year from 1978 to 2004
inclusive.

As you will see, the coldest day of the year in Coventry avaerges out
at 28th February - much later than you might have expected.

Just out of interest. I have appended other data from our website:

Warmest day of the year 28th July

Warmest night of the year 27th, 28th, 30th July

Coldest day of the year 16th February

Coldest night of the year 13th January

Wettest days of the year 29th July and 6th December

Driest day of the year 28th February

Sunniest day of the year 24th July

Dullest day of the year 1st December

Windiest day of the year 23rd March

Calmest day of the year 25th Septeber

Some surprises there!
