I've recorded 20 degrees in October on several occasions, including twice
this year (20.0 on 5th, 20.1 on 15th)

My highest October temperature this decade being 22.1 on 13th Oct 2001.

This is where monthly stats fall over, because 21 C is probably no big
deal for the 1st to 7th of October, but 27th?

5 more days and we will be in November, and how many 21Cs have there
been in that month, even on the 1st?
