Growing Degree Days (GDDs)
This map displays the latest accumulated Growing Degree Days (GDDs) since 1 September 2015 in the Waipara wine-growing region. GDDs were derived from the weather conditions forecast by the WRF model. The black dot indicates the Waipara growing-region.
This page will be updated regularly. So come back later to check out the latest GDD developments in the region.
Please note that the Growing Degree Days are determined using a base temperature of 0˚C, as in the Grapevine Flowering and Veraison model (Parker et al. 2011).
