1999 coldest place overnight each day

Please note that the readings below are taken from the Met Office's Daily Weather Summary which is produced three months later. It includes a larger data set. This includes climate sites which report manually and aren’t available when the UK Daily extreme temperatures are published around midnight each day.  Therefore the Daily Weather Summary is the definitive product. https://digital.nmla.metoffice.gov.uk/
