The wettest winter month ever recorded in Oxford (for 250 years)

Oxford has one of the longest weather records in the world, stretching back to the 1760s at the Radcliffe Meteorological Station. This January has been the wettest winter month ever recorded (winter months = December, January, February), with rainfall almost three times the average.
The result is floodplains that have become vast lakes, as seen in these photos of Port Meadow during my morning run/wade. Port Meadow tends to flood in most wet spells, but I have never seen it so awash with water.
