Does night bring relief
from the Florida 90 º midday heat?
Then “yes” – about 15º worth.
(Night time lows hover around 75º F on most summer nights.)
As accurate as that thermometer may read, it couldn’t be more wrong: It’s on the needle of the psychrometer where the true answer lies –
It measures humidity.
Keeping the air uncomfortably “sticky” and – as plotted on the heat index above –“very warm.”
That’s why if you venture out into the dark in Florida on a quiet summer eve, among the other things that you’ll hear is the low rumble of running air vapor being condensed.
Or in other words: Air conditioners.
That’s the same temperature as the night-time low.
The only difference? – Humidity.
So, to answer the original question –
“Yes, night does bring relief from the Florida heat …
inside the house with the AC running.”
