The tables below show the accumulated chill hours so far for 2017-2018 in Yuba City, as well as historical chill data. They will be updated weekly – bookmark this page for future reference.

For more information on differences between chill models, read about calculating winter chill. Chill accumulation, calculated from CIMIS stations around the state, can be tracked using the UC Fruit and Nut Center chill accumulation models. Janine Hasey provides these data from Yuba City because there is no local CIMIS station.
