OLM update!
It turns out their 1990-2012 summer average was 62.1.
Their coldest post-2012 summer was also 2020, at 62.8. So essentially an identical story to PDX.
Their post-2012 summer average is also 2 full degrees warmer than the 1990-2012 average.
And since pre-1970 came up, their pre-1970 summer average was in fact a little cooler at 61.5, or about 1.3 degrees cooler than their post-2012 benchmark.
Also, since there's been some talk on the street about 2025's noteworthy underperformance, the June-September 2025 period overall ranked as the 6th hottest on record at OLM. Again the same as PDX, which also saw it come in 6th.
Who knew OLM and PDX were friends after all!!?? Go stats and go team!!
