This is part of our quarterly home performance reporting. All data is posted at

I said it last year and I’ll say it again, it was a whacky winter. Lots of cold days, but also lots of warm days. It would be warm for a week or two, the ground would thaw, then we’d get snow.

We recorded a low of -17.1 on January 7, close to our lowest recorded temperature of -17.3°F on February 14, 2016. Our high was 77.6, higher than the 73.6°F last year. In 2012 we recorded a high of 82.4°F in the same period.

Overall, here’s how this quarter compared to 2017.
