Confession: When I did the above calculation, I overdid the temperature for the very first day (last Thursday) by almost 6 degrees, due to a sneaky midnight temp that I missed. That, along with a few other days coming in cooler than expected, is going to lead to this calculation being off by a solid half degree. Unacceptable on my part, and I swear to never let this happen again. Well, at least until the next time it happens. In closing, with one day left in the month (bold I know haha), I can now confidently say that the final mean monthly temp for October will be 57.6 degrees, good for a T-28th place with 1975. I humbly ask for your forgiveness. Ciao.
