I am hoping someone can confirm chill hours in my location. I am in Moraga, CA. It is zone 9b. I have used multiple sources to determine my average chill hours per year. The number from multiple sites is over 1000 below 45 degrees. It seems high, so I am not sure if I am just misreading. Thanks for any help.

Welcome, this is what I found that can help you find how many chill hours your area has. From what I am seeing since the hours started counting in late October you have about 1500 hours already. Here is a link of the chill hour calculator.

Welcome to the forum. This year’s chill hours is kinda out of the ordinary, way more than normal across Northern California. In Sacramento county, it is already 1300+ hours. During normal years, it is around 800-1000 hours. From your local CIMIS data, I think you can take average of 2018-19 to 2021-22 years to get better idea of average chill hours in Moraga.
Thank you both. That is the source I was looking at. Just wanted to make sure I was reading it correctly.
