When I post a [WR] which contains a figure for a day temperature extreme
in a given period I describe that as the 'highest/lowest temperature
'for that period.

When I post a [WR] which contains a figure for a day temperature mean
extreme in a given period I describe that as the 'warmest/coldest day'
for that period.

Others, I notice, describe a day with a day temperature extreme in a
given period as the 'warmest/coldest day 'for that period.

In other words, the maximum day temperature, using my phraseology, may
not give rise to the warmest day even though it may be the highest
temperature.
