New Zealand Monthly Rainfalls...
Tauranga

 
 
"... for He makes his sun to rise on the evil and on the good, and sends  rain on the just and on the unjust".
 
Matthew 5:45
******************************************************************** 
 
Monthly rainfalls for Tauranga (New Zealand) have been recorded at several recording sites over the last 117 years. 
 
From January 1898 to December 1904, the observation site was the Tauranga Harbour, from November 1904 to April 1907 the site was "Tauranga", from January 1910 to December 1923 the sites was Waikareao in Otumoetai, from January 1924 to September 1940 the site was at 148 Waihi Road in Judea, from October 1940 to January 1941 the site was at Te Puna, and from February 1941 to the present,  the site is the Tauranga Airport.
 
C.S Thompson of the former New Zealand Meteorological Service computed a homogeneous rainfall series for Tauranga and some other stations in New Zealand, appropriate to the recording sites, and the methodology use is published in the NZ Meteorological Service  Miscellaneous Publication No 180 in 1984.
 
 
Although adjusting rainfall observations from one site to another is not without its difficulties, it is considered that the homogeneous rainfall series decribed in this web page is a fairly true record of what the rainfall would have been if the current observation site had been used since 1898, with the understanding that although standard accepted methodogies are used, any adjustments are only estimates of what would have occured IF the location of the rainfall records had always  been in the same place with the same surroundings, and the recording gauge.
