World Weather Records

Note: For 10th Series WWR 2001-2010 country submission information please contact Russell Vose (


World Weather Records (WWR) have been published since 1927, and include monthly mean values of pressure, temperature, precipitation, and where available, station metadata notes documenting observation practices and station configurations.  Data were supplied by National Meteorological Services as members of the World Meteorological Organization (WMO), and links to all WMO member national Meteorological Services can be found at

The First Issue included data from earliest records available at that time up to 1920. Data have been collected for periods 1921-30 (2nd Series), 1931-40 (3rd Series), 1941-50 (4th Series), 1951-60 (5th Series), 1961-70 (6th Series), 1971-80 (7th Series), 1981-90 (8th Series), and 1991-2000 (9th Series). The present series continues, insofar as possible, the record of monthly mean values of station pressure, sea-level pressure, temperature, and monthly total precipitation for stations listed in previous volumes. In addition to these parameters, mean monthly maximum and minimum temperatures have been collected for many stations and are archived in digital files by the National Climatic Data Center (NCDC), USA. New stations have also been included.
