Chill hours in Australia
Ten-season averages for 25 locations in Australia, from NASA POWER hourly temperatures. 6 of them have a full page with the season-by-season table and the fruit trees and berries that suit them.
Where fruit grows in Australia
Australian orchards sit in cool pockets a long way apart: the Goulburn Valley and the Southern Highlands in the southeast, the Granite Belt in Queensland, the far southwest of Western Australia, and Tasmania. Chill accumulates over the southern winter, so the season labels here are single years rather than the split years used in the Northern Hemisphere.
Across these locations the ten-season average runs from 0 chill hours at Sydney, New South Wales, to 1700 at Huonville, Tasmania. 45°F Hours and Utah are counted over 1 May – 31 August.
