Over the 30 growing seasons from 1991 to 2020, Wachau's vines saw on average 970 growing degree days between April and October. That puts it in Winkler region I, close in heat and rain to Mosel, Central Otago and Rheingau. In a typical year about 518 mm of rain falls in the growing season, 119 mm of it in September–October.
Since 2000 the warmest season was 2018 (+42% against normal) and the coolest 2004 (-16%). The wettest harvest window was 2024, with 278 mm against a normal 119 mm.
The last 10 vintages (2016–2025) averaged +16% against the 1991–2020 normal, compared with +1% for 2000–2009; 8 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 (970 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 (September–October). The line is the normal season total, 518 mm.
