Last month here. Fastest cooldown is from 6 PM to 7 PM (just after sunset). Also note the distinct stagnation in temps around 1-2 AM before resuming later on in the night.

Plotting the time derivative of temp to get the average rate of cooling or warming. Radiational cooling is highly front-loaded; more cooling occurs from 4 PM to 5 PM (before sunset) than occurs from 7 PM to 8 PM (or any time in the night after that).

Seems that year round, our peak is between 3 and 4pm, and valley is 30 to 60 mins after sunrise

A few nights this month had cloud cover increase around that time of night. More generally though, once it cools close to dew point there is some heat released by vegetation which temporarily delays further cooling.

Average rate of temp change per hour. Deffo more steady temps, especially this time of year
