Mitta has a great climate with season differences that enhance the natural beauty. Local aboriginals noted five distinct seasons, the 'extra' season between spring and the rather late onset of summer. Rainfall is predominately during spring and annual average rainfall is around 1049mm. Droughts occurred during 1901-1904 ('Federation Drought'), 1906 and 1997-2009. Big floods occured in the Valley in 1885, 1905 and 1906 inundating houses and properties. The completion of the Dartmouth Dam upstream of Mitta has basically taken away the risk of serious future flooding.
