I had an odd thought just now: suppose this year was a leap year - what
would the mean temperature for February be?

The mean temperature for the 1st March was -0.5C - adding this to
February's temperatures as though it was the 29th February brings the
February mean down by 0.2C. As February was 0.1C above the eLTA, that
would be the difference between a slightly above average month and a
slightly below average month temperature-wise.

Then I thought: but the end of February is quite often cold. So does the
leap-year effect show up? Are there statistically more cold Februaries
attributed to leap-years than other years?

I might be wrong, but as least it might provide someone with a few
interesting minutes to find out
