Summer 2016

Now that Summer 2016 is but a memory, let’s take a quick look back at where it stands in the record books.

Temperature

Summer 2016 Means
June-August Mean High: 85.5
June-August Mean Rank since 1878: 26th Warmest
While the average high for Summer 2016 was certainly warm, it fell just outside of the top 25. By comparison to recent years, 2010 (85.6), 2011 (85.7) and 2012 (87.7) all had warmer average highs.

June-August Mean Low: 66.1
June-August Mean Low Rank since 1878: 4th Warmest
The average low for the summer is what made 2016 much more exceptional. No recent years (last decade) were warmer, although 2010 did tie.

June-August Mean: 75.8
June-August Mean Rank since 1878: 10th
So if you thought this summer was hot, well you were right. Only 2010 (75.9) and 2012 (76.4) were warmer of any recent years.

Monthly Means
June Mean: 73.2
June Mean Rank since 1878: 17th Warmest
July Mean: 76.6
July Mean Rank since 1878: 20th Warmest
August Mean: 77.6
August Mean Rank since 1878: 6th Warmest
The summer gradually became hotter as it went on.

# of 90+ Days: 18
90+ Days Rank: 22nd
Warmest High: 95
Warmest Low: 77
Coldest High: 72

Daily Temperature Records
June 11th: Record Warm Maximum Tie: 95: Tied with 1914 and 1933.
August 10th: Record Warm Minimum Tie: 75: Tied with 2001.
August 11th: Record Warm Minimum Tie: 76: Tied with 1918.
August 12th: Record Warm Minimum: 76: Beat record from 1947.
August 13th: Record Warm Minimum Tie: 75: Tied with 1995.

Precipitation

June-July Precipitation Total: 13.53″
June-July Precipitation Rank since 1878: 29th Wettest
Besides being warm, Summer 2016 was also fairly wet.

Monthly Precipitation Stats
June Precipitation: 5.22″
June Precipitation Rank since 1878: 29th
July Precipitation: 2.49″
July Precipitation Rank since 1878: 27th Driest
August Precipitation: 5.82″
August Precipitation Rank since 1878: 13th Wettest
So the summer was bookended by wet months with July being fairly dry.

Summer 2016 Misc. Precipitation Stats
Total Precipitation Days (including Trace): 45
Total Measurable Precipitation Days: 30
Measurable Precipitation Days Rank since 1878: 16th Highest
Days with 0.25″ or Higher: 16
