¹ The time for the Past 24-hours values is the time those
values were last updated. It is usually before the current time
because the history values are only updated every few minutes.
² The average given here is
the arithmetic mean: Σxi/N where the sum is
performed over the available data for the previous 24-hour period.
Normally the available data is the 1-minute average (arithmetic
mean of data taken once per second) for temperature, humidity, mean
sea-level pressure, station pressure, solar insolation, and
dewpoint. For wind chill the 1-minute value is the minimum
recorded over that period. For wind speed and heat index it is the
maximum during the period.
³ The average wind direction is the vector average
which incorporates both the direction and speed. It is the
net direction a parcel of air would have moved if you could track
it over the 24-hour period.
