I'm surprised that Feb 1956 doesn't feature.

So was I, but it scored +1.5 mbar, a reflection of the westerly
component over the northern half of the UK. It was, though, one
of the half-dozen most anticyclonic Febs in the last 130 yrs.

Apart from Feb 86 and Dec 95, other recent months which
were easterly included Jan 96 (6.1mb), Mar 96 (5.7mb),
May 93 (4.6mb), Oct 93 (4.5mb), Apr 00 (4.2mb),
May 94 (4.1mb), Dec 02 (4.0mb), Sep 93 (3.8mb) and
May 88 (3.0mb). So they still do happen.

The two autumn months in 1993 stand out.
