You can say that again.

I really hate it when the temperature soars between 8 and 9 am. Quite
often in winter the maximum is 8.59 a.m. December 21st here was very
cold - a maximum of -2.4C during the day, dropping to -6.8C around 2
am, then climbing rapidly to -1.4C at 8.59, thus spoiling my record
lowest maximum. And there have been several occasions where an
otherwise "frost day" has been ruined by rising temperatures around
dawn (which is 8.45 a.m. here).
