Summer 2015 Was A Bit Cooler Than Average

OSWEGO, NY – Summer 2015 goes into the record books just a tad cooler and a bit wetter, according to Bill Gregway, local observer for the National Weather Service.

Fall officially starts on Wednesday, Sept. 23, at 4:20 a.m., the autumnal equinox.

For his record keeping, Gregway lumps the seasons into 3-month groups with June, July and August being summer.

The average temperature for this summer was 67.7 degrees. That is just 0.8-degree below average.

There were no 90s, Gregway pointed out.

The highest temperature was 89 degrees on July 7 and the lowest was 40 degrees on June 7.

The 40 degrees was a new record for that date, Gregway added.

Summer had 23 days where the high was in the 80s.

The overnight low was in the 70s on 4 occasions – 3 in July and 1 in August.

Total precipitation for the summer months came in at 11.46 inches. That is 1.21 inches above average, Gregway said.

“It would have really been dry had it not been for June. That month received nearly 7 inches of rain (6.91),” he said.

However, the most precipitation to fall in a 24-hour period came in June.

“We had 2.45 inches on June 1; 1.75 inches fell in just 2 hours,” Gregway said. “We also had 1.34 inches on June 23 and 1.14 inches on June 8-9.”

Measurable precipitation fell on 40 days and no precipitation was recorded on 52 days.

The number of cloudy days, 30, was 1 above average.

The number of partly cloudy days, 43, was 7 above average.

The number of clear days, 19, was 8 below average.

The area received 59 percent of the possible amount of sunshine. That is 7 percentages below average.

There were 7 thunderstorm days. That’s 9 below average.

Summer had 11 foggy days, which is 10 above average.

The highest barometric pressure was 30.26 on June 3. The lowest was 29.52 on July 14.

“We had some pretty good winds all three months,” Gregway said. “In some places they were greater than 30 mph. The directions were all over the place.”

It was a rather cool summer, Gregway said.

The most recent coolest was in 2009 when it was just 66.3 degrees, he added.

The warmest summer was 73.0 degrees in 2005.

“This summer wasn’t even in the top 10, or 11 or 12,” Gregway quipped.

The coolest was 63.2 degrees in 1869.

Last summer was 67.8 degrees (0.7-degree cooler than average).

“Last year, summer was pretty close to this year,” Gregway said. “It was almost a mirror image.”
