This is turning into the year without a summer. We've had just one week's worth of 85-degree-plus temperatures and three 90-plus days. I'm not complaining--it's 65 right now and quite pleasant.
I had heard that Boston and New York were having mild summers and I did a quick check of the numbers. Quite mild indeed. Boston has had two days over 80--83 on June 7 and 84 on June 26, and 16 days of highs in the 60s during June. More than half the month with mid-spring high temperatures. New York City had five days in June with highs in the 60s and no day warmer than 83.
