Northern Ireland had the wettest January since 1877, with an unusually high amount of rain.
195.6mm fell across the month – making it the second wettest year since official records began nearly 200 years ago.
Other areas which also experienced a lot of wet conditions included south-west and southern England.
There was 74% more rainfall than is typical for the month – enough to rank it the sixth wettest on record for the area.
At a county level, Cornwall in south-west England and County Down in Northern Ireland both experienced their wettest January on record.
