Over the 30 growing seasons from 1991 to 2020, Hunter Valley's vines saw on average 2,380 growing degree days between October and April. That puts it in Winkler region V, close in heat and rain to Southern Rhône, Kakheti and Valpolicella. In a typical year about 543 mm of rain falls in the growing season, 172 mm of it in January–February.
Since 2000 the warmest season was 2019 (+10% against normal) and the coolest 2012 (-10%). The wettest harvest window was 2013, with 301 mm against a normal 172 mm.
The last 10 vintages (2016–2025) averaged +4% against the 1991–2020 normal, compared with -1% for 2000–2009; 7 of those 10 seasons were warmer than normal by more than 3%.
Growing degree days (base 10°C) for each season. The dashed line is the 1991–2020 normal (2,380 GDD) and the shaded band one standard deviation either side: about two years in three fall inside it.
Full bar: rain over the whole growing season. Dark part: rain in the harvest window (January–February). The line is the normal season total, 543 mm.
