Rainfalls for the month of June have been recorded in Tauranga since 1898 (except for 1904, 1907, 1908, and 1909).
The graph shows the range of rainfalls from an extreme high of 381mm in 1925 to a low of 19mm in 1906. The second wettest June was 1920, when 309mm was recorded, and the second driest June was in 1959 when only 27mm fell. The long-term average rainfall for Tauranga for June is 131mm.
The graph of the June rainfall shows ‘normal’ variations form year to year. There is a small decrease in the overall June rainfalls during the last 50 years (1961-2010) from an average of 126mm, compared with an average of 139mm during the 50 years from 1911-1960. This is similar to the months of January, February, April, and May for the same periods, which also show small decreases in the overall rainfalls during the last 100 years, compared with a small increase in the March rainfalls. Since 1898, there have been 16 June months with a rainfall of 200mm or more, but only five June months with rainfalls of 40mm or less.
