It's interesting that your location in Seattle did so close to average this year. I ended up with 34 freezes for the winter while my average total over the last 13 years is closer to 45. I had one measly freeze in December, 3 in February (only one of which was actually sub 32F), and my last freeze was 3/7 which is significantly earlier than normal. Although, now I look back at it, my total this winter was pretty comparable to my total for the 19-20, 20-21, and 21-22 winters.
