2016 Temperatures: HLA
HLA = High/low average
Every day, I averaged the high and low for the day, and then I averaged all days for each month. The results are the gray dots connected by gray lines.
At the end of the year, I averaged all the daily HLAs to get the yearly HLA, which is the orange line at 71.17°F.
(The red swath is the range of highs for each month. The blue swath is the range of lows for each month. They overlap for most months, which shows as purple.)
NOTE: 2016 was very rare in that July's HLA was higher than August's.
