Original post:
With a high on Friday of 86°, New York City broke its record spell of 46 consecutive days without reaching 85° since June 1. The last time the temperature failed to hit 85° in June was 1916. The only previous occurrences were 1903 and 1886. This June was tied for the 8th coolest, and it was the second wettest in history. From the National Weather Service public information statement:

So you quote the outlier data set that says Juen was warm. Care to report the findings of the other data sets or maybe, how about this for a change, take a look out of the window! You can massage the data to fit your agenda but you can't change what people are experiencing.
