So it doesn't show a difference in climate but in elevation. The 13°C = ski and golf in the same day only applies to climates with high mountains.
At a 13C average maximum. there will still be snow down to 300-400 metres at times, as well as frequent frost. Would that be true of your area during the period of a 13C average maximum?
Well, you are going to need mountains to ski (cross country isn't real skiing)

Lol, certainly not in PA with our paltry mountains. NZ has much higher mountains than the eastern US I think. Your area would def be more like the western US where that could happen. I'm not sure about New England mountains, but my guess would be that any day that got a max over 50F in winter, there would likely be rain on the New England mountains. At least the few times I went to Killington for skiing that was my experience.

At times, but usually wet days have relatively flat lapse rates. Last month, most precipitation ocurred on warmer days. Christmas Eve had a 60°F dewpoint in the NYC area, this resulted in a high of 46°F on Mt. Washington. It depends on the synoptics, but average maximum of 13°C has a high chance of rain up in the mountains.

Yep, as I thought.
A 10C day with rain here, would mean snow to a low level here (1500ft). The nearest mountains are high enough (6000ft), so that even when the maximum is averaging 18C (October,) snow will still be more common on the summits, than rain.

Pinkham Notch below at 2000 feet had an average maximum of 41°F, mostly rain there.
At times, there can be major differences with the temperature down here, while it's snowing on the tops. A couple of summers ago, it was a 22C day here and the mountains picked up fresh snow during the day. I'm guessing it was a weak SW change, stalling behind the mountains.

Take some pics of those beautiful mountains. Shots I have seen online look amazing. Very green down below, and then soaring white capped mountains. New Zealand has it all over Australia when it comes to mountains. Australia is the flattest continent on earth, and their many of their mountains look like hills lol. Same as in the east here, most of our mountains look more like rolling hills.
Americans from the west always mock our East Coast mountains as hills.
2015 was interesting, to say the least. Started out quite cold, February was one of the coldest months ever recorded, spring was a little slow to arrive in March, but after that it was a sea of record breaking warmth. NYC saw the warmest September, November, and December on record, it broke the record for the longest period at/above 32F/0C (Mar 29 to today, Jan 04) and set a plethora of other records.
Overall I give it a B-, Jan/Feb () and half of March are the only detractors from an otherwise great year.
Here's the average highs and lows for the year near me, about 100 miles WSW of New York City -
Upper Bucks county, PA (F temps).
Jan. 33---17
Feb. 29---9
Mar. 43---24
Apr. 62---39
May 78---52
Jun. 79---61
Jul. 84---64
Aug. 84---60
Sep. 80---58
Oct. 63---43
Nov. 57---38
Dec. 54---39
PS - amazing how my average low only dropped 4 degrees from October to December, and how the average high rose 35 degrees from March to May

-17C is impressive though. That would even warrant my 'warm' parka albeit only tshirt underneath.

February is borderline subarctic with the lowest low of -17C. Summers are too hot and humid (22C lows are impressive at that latitude). NYC is an interesting climate, but in a bad unforgiving way.
-17C is impressive for NYC, but what I find even more impressive is that the wind chill was around -29C when the -17C happened.
An awesome day, to say the least, though not subarctic.
I think the lapse rate may be higher in NZ than in the Northeast US?
Lapse rate varies, but usually with wet conditions it's a rather low rate in the Northeast. With dry, continental air especially in the warmer months it can be rather steep. I was at the top of Mt. Washington in early August once when it was 43°F at the summit. 5500 feet below it was 30°F warmer. Precipitation often gets warmer mid-levels, depends on the system.
