In the unsmoothed data, August 19, with 
78.8°, is the warmest. 
If the raw data are smoothed to hundredths 
as 7-day progressive means, we get August 21, 
with 78.50°, as a trifle warmer than any 
other date. 
Thus, the three methods give three suc- 
cessive dates, August 19, 20, and 21, from 
which we may choose August 20 as the 
warmest date.
