Yes. I mentioned on the first page of the "How to get Climate data" sticky. From the first link, choose "Custom Monthly Listing". I thought posters were aware of where to get that information since was on the sticky and I think I've linked to it previously on some of these threads.

Got it . I will not create these threads any longer.

Last few years:

2013: 95+ degrees: 3 times, 59- degrees: 0 times.
2012: 95+ degrees: 4 times, 59- degrees: 0 times.
2011: 95+ degrees: 4 times, 59- degrees: 0 times.
2010: 95+ degrees: 5 times, 59- degrees: 0 times.

Get the picture?

It's hard to get below 60 in NYC in July, because the urban heat island effect is combined with the midsummer airmasses.

Before the 1980s, it was not as hard. It was still pretty rare, but it was one of those things you saw every few years, not every couple of decades.

NYC takes 95F highs in July from Mother Nature like a kid takes candy, and NYC takes sub-60F highs like a kid takes broccoli.

Dress accordingly? How would that be a problem, unless shorts and short sleeves are unsuited to hot weather? Also, even after I'm used to summertime weather a 59F low with >50F dews still feels warm and humid (albeit much less so than humid 60's), and the vast majority of the day will be spent well above 60F.

And I never noticed how lopsided our temperatures are, 95F seems way more common than high 50's in the summer.
Many tropical climates are cooler at night than NYC is during summer. In terms of stable weather (particularly at night) and high dew points, for most of the summer a huge zone from NYC to the equator has remarkably similar weather patterns. Sure, there's the occasional cool front, but predominately NYC is stably hot and humid during summer; at NYC's latitude, it helps to be next to a warm ocean, a wet subtropical zone to the south (as opposed to a desert), and in an urban heat island.

What tropical climates average cooler night temperatures than NYC? Maybe the dry season of wet and dry tropical climates, otherwise no.

The funny thing about NYC is its insane UHI. Go 60 miles north and your summer lows are drastically different with mid 50's occurring more often in July. The average low in Poughkeepsie,NY an exurb around 60 miles north on NYC is 59 F, approximately 8 F lower than that of NYC.

Much of that is from being away from the ocean. A better comparison would be a site away from the city near the water.

Setauket, Long Island. Average July low 64.8°F [about 55 miles east].
Westhampton, Long Island. Average low 63.4°F [about 100 miles east and a big frost hollow]
NYC — JFK. Average low 68.4°F
NYC — Central Park. Average low 68.8°F

So about half from the heat island, half from the ocean. And the effect on daily highs is much smaller.

Shorts and short sleeves are unsuited for 50's, not hot weather, which is why one would have to dress accordingly. I can only speak for myself of course, but I know I'm not alone in thinking that 50's would be cold to people who are used to nights in the 70's.

People think Floridians are crazy when they're wearing jackets when it's below 70F, but they're not. Last July NYC's average low was in the mid 70's, and when we dropped to 64F one morning I was shivering uncontrollably in shorts and short sleeves. I'm glad we rarely see 50's in July, but everyone's entitled to their opinion.
