Highest minimum

[rayauger]

Hi,

How do you calculate the highest minimum which to me means the warmest night ?. Is it based from sunset to sunrise or midnight to midnight ?

AIUI, in Cumulus, it is the highest minimum for a 24 hour period, which will either be midnight to midnight or 9am to 9am depending on how you have configured the roll-over time.

Although it will often refer to the warmest night, it needn't necessarily be so. For instance if your warmest night (say 15°c) occurred in a 24 hour period in which the temperature dropped at one point to 10°c, it might not be recorded as the lowest minimum if another 24 hour period had a minimum of 12°c.

Yes - I think that strictly speaking, under some meteorological rules in some countries, it should limit the periods over which it checks for max and min.
