Greek weather records

Dates prior to 1 March 1923 were converted to Gregorian calendar dates. Data on this page derive from the Hellenic National Meteorological Service, the National Observatory of Athens, official references in the Greek press and personal weather stations. Deviations from the actual data are possible. Any possible measures, such as double checking all data before presenting it here, have been taken or are currently untertaken; however, this cannot guarantee complete infallibility of the presented data. The latter should, therefore, not serve as source of information for planning or undertaking any activities. Interested individuals or parties should refer to the national authorities for more detailed and/or official data.
