While the calendar says that summer ends on Monday at 10:29pm… meteorological summer has already come to an end. Climatologically speaking, the warmest 3 months of the year are June, July and August. So with the book on meteorological summer closed, lets take a look back at the summer of 2014, and how it stacks up against some other recent summers.
The image above takes a look at the combination of June, July and August for the past 6 years. After an above average June (+1.8°) and a near normal July (+0.6°)… Poughkeepsie, NY had the coldest August in the past 5 years (-1.3°). When you add those three months together, you get the coolest summer since 2009. Even still, the summer as a whole, was above average… barely. In 2014, the highest temperature was 93°… the lowest maximum temperature we’ve seen since 2009, so it was by no means “hot”. So if you’re wondering how on earth the summer of 2014 was above average… you need look no further than the night time lows. The coldest temperature we saw in the summer of 2014 was 48°… the highest minimum temperature in the 6 year period. The real reason why this summer was above average was due to warm nights, which averaged +1.6° thru the summer… compared to the daytime highs, which were -1.2° compared to normal. So this summer didn’t feel warmer than average… but thanks to mild nights, it was.
Keeping in mind that due to thunderstorms, summer rainfall amounts can vary significantly over short distances… the Poughkeepsie rainfall analysis of the past 6 years was quite interesting. Every other year the story seems to change. The odd years, (2009, 2011 and 2013) were all well above average in terms of rainfall. 2011 was experiencing relatively normal rainfall… and then Tropical Storm Irene hit.
Then in the even number years… 2010, 2012, and 2014… we only saw roughly 80% of what we would normally expect. We haven’t had any drought situations in the past 6 summers, even if we have had a few that were a bit dry.
So the summer of 2014 was not all that abnormal, in terms of averages. The days were a bit cool, the nights were a bit warm, and the rainfall was about 20% below normal. Compared to the 5 years before it… there were some similarities and some differences. But regardless, it can be fun and informative to put the weather into hard data to compare. We hope you enjoy the look back, and find it useful.
