Book A Guided Walking Tour

This post gives you a general idea for when it starts to get warmer in New York City. 

We include details about the average amount of sunny days, rainfall, and other factors you might want to consider.

The first time you can expect the average temperature to rise above 40 F (6 C) during the day is late in February.

There may even be a few days with temperatures over 50 F (10 C).

February usually means at least a few days of snow, but you can also expect sun on about 17 days of the month.

March will bring as many as 19 days of sun, around 10-11 days of rain, and temperatures between 50 F (10 C) and 65 F (18 C) in the daytime on certain dates.

If you’re hoping for at least 70 F (21 C), chances are you’ll have to wait until April daytime hours. 

This is also the month when we start to offer a lot of our night tours in New York City, as the temperatures at night are a much more bearable 45 F (7 C) to 50 F (10 C) starting at this time of year.


When Can I Take Off My Jacket?

This all depends on your tolerance level for chilly weather. 

For most people, chances are that the weather in late May will have you taking off your jacket, as temperatures can get as high as 75 F (24 C) - 85 F (29 C) during the day.

When Does the Weather Become More Comfortable?

Most people will feel comfortable going out to places like Central Park and enjoying the outdoors in either April or May. 

That said, there does tend to be some rain during the spring, so you might still want to bring a jacket.

Average April Weather

If you’re interested in seeing some outdoor sports, Yankees and Mets fans can look forward to baseball starting in either late March or early April. 

Festivals and outdoor markets usually open up in Late April or early May.

Interested in some activities after dark? The spring will more than likely be the first time when the weather becomes comfortable at night.

Don’t forget that our pay-what-you-wish night walking tours begin in April!


When Does it Get Hot in NYC?

Although what is considered hot is subjective, what isn't subjective is that July is the hottest month in NYC.

In the past, July has seen extremes here as high as 106 F (41 C).


When Does it Start Getting Colder?

Well, believe it or not, the average temperatures start dropping off pretty quickly in mid-to-late August, and some days may even hit the low 70s (21 C).
