Your April weather guide
MildWeather in New York in April
April is a reasonable time for New York if you want a city break in mild weather, rather than reliable warmth. Average daytime highs are around 15°C, but nights fall to about 5°C, so packing only for spring sunshine would be a mistake. With about 11 rainy days, flexible plans matter. Go if you are happy walking in layers and changing plans when it rains; choose another month if warmth is the priority.

Within United States it is 6th of 6 (United States in April). Against London's average high of 13.5°C in April, New York is 1.6°C warmer by day and 0.3°C warmer at night.
Daytime and night-time in April
The typical April day in New York peaks at 15.1°C, but that is an average: the warmest 10% of days reach 21.9°C or more. Roughly 1 in 29 days top 25°C and 1 in 333 pass 30°C. Nights average 5.4°C; one night in ten drops to 0.8°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest April day here reached 31.9°C (2002-04-17) and the coldest night -3.6°C (2016-04-05).

Wet (more than 8 rainy days): about 11 days with 1 mm or more, 92 mm in total. Year to year it varies a lot - the wettest April was 2007 with 207 mm, the driest 2013 with 31 mm. Humidity averages 68%.

A little warmer than London, but keep your coat
New York's average April daytime high is just 1.6°C above London's, so the difference is modest rather than a reason to travel for heat. Mild afternoons can suit spending time outside without summer heat, but the range matters: the warmest 10% of days reach 21.9°C or more, while the coldest 10% of nights fall to 0.8°C or lower. Pack layers you can remove during a warmer afternoon, along with a coat that feels comfortable after dark. Do not count on T-shirt weather throughout your stay. Days reaching 25°C account for only 3%, so a warm spell is a bonus rather than something to build the trip around.
Plan for wet spells, not just spring sunshine
April is wet enough that rain should shape your packing and plans. Bring a waterproof outer layer and footwear you are comfortable walking in when pavements are wet. About 5.2 hours of sunshine sit within 13.1 hours of daylight, so long days do not mean uninterrupted sun. Keep outdoor plans movable and leave room for time indoors when conditions turn unpleasant. The daylight gives you flexibility to shift a walk to a brighter part of the day, rather than pressing on in the rain. This is a workable month for travellers who can adapt, but a less convincing choice if your enjoyment depends on being outdoors throughout the day.
