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

The summer gradually became hotter as it went on.

Summer of Rain 2015

This summer has been wet… very wet. Rain has fallen on far more days than not, and cloud cover has hung thick and heavy in what are historically much sunnier months. To top it all off, temperatures have been somewhat below normal.

How wet has summer 2015 been up through today? Meteorological summer runs June 1st-August 31st, and today makes the midpoint of that period, so I thought it would be a good time to check in and answer that question.

Here are the top 10 wettest summers through yesterday.

1. 1958: 12.54″
2. 2008: 11.68″
3. 1990: 10.93″
4. 2015: 10.66″
5. 1949: 10.40″
6. 1973: 10.23″
7. 1917: 10.06″
8. 1928: 10.02″
9. 1937: 9.75″
10. 1969: 9.38″

So 2015 is running the 4th wettest. It looks to be dry the next few days before more thunderstorms and rain return, so 2015’s position may end up rising.

What are the wettest full summers of all time? A few of the above years went on to be in the top 10, but not all.

1. 1958: 22.02″
2. 1979: 20.92″
3. 1995: 19.85″
4. 2003: 19.39″
5. 1969: 19.09″
6. 1915: 18.92″
7. 1992: 18.44″
8. 1973: 17.81″
9. 1989: 17.45″
10. 1949: 16.54″

Summer 2015 needs about 6″ more to reach into the top 10 wettest summers, which at the current pace is more than possible.
