This calendar is genuinely different

Most travel resources show you averages — what typically happens in a given month based on decades of blended data. This calendar shows you something far more useful: what actually happened in New York City, day by day, throughout 2025. Real highs, real lows, real rain, real wind — sourced directly from the U.S. government and color-coded so you can read the entire year at a glance. Open any month and the temperature story unfolds instantly in color, from deep violet winter days through the fiery reds of summer. Tap any individual day and you get the full picture for that specific date.

This is official U.S. government data

Every reading on this calendar comes directly from NOAA — the National Oceanic and Atmospheric Administration, the U.S. government agency responsible for the country’s official weather records. This is the same data used by scientists, researchers, and news organizations worldwide. It is not estimated, interpolated, or commercially produced. It is the authoritative record of what the weather was, on each specific day, in New York City’s Central Park.

The Central Park station

The data comes from the weather station at Central Park (Station ID: GHCND:USW00094728) — the gold standard for New York City climate measurement. Located in the heart of Manhattan, it has recorded daily weather continuously since 1869, making it one of the longest-running climate records in the United States. When meteorologists, researchers, and journalists refer to “New York City weather,” this is the station they’re citing. Each day card also shows the all-time record high and low for that calendar date, drawn from all 156 years of this station’s history.

How to use it for trip planning

Open the month of your planned visit and scan the colors — you’ll immediately get a feel for the temperature range. Tap any day card to see the full detail: high, low, average, precipitation, wind, snowfall, and how that day compared to historical records going back to 1869. Use it to decide what to pack, compare different travel windows, or understand what “a warm NYC October day” or “a cold January night” actually means in practice. Traveling from outside the U.S.? The °C Metric toggle above switches every number instantly.

🌟 A note about 2025: June 24, 2025 reached 99°F / 37°C at Central Park — breaking a daily record that had stood since 1888. That means 2025’s hottest day shattered a 137-year-old record. You’ll find it in the June calendar, marked with a special ring. The all-time records shown on each day card reflect the complete history from 1869 through 2024, giving you the full context for everything you see in this calendar.

Frequently Asked Questions — NYC Weather for Travelers

01
What is the best time of year to visit New York City for good weather?
Late spring (May–June) and early fall (September–October) are widely considered the most comfortable times to visit. Temperatures are mild, typically in the 60s and 70s°F / 15–25°C, crowds are more manageable, and outdoor activities are at their best. Open those months in the calendar above to see exactly what 2025 looked like day by day.
02
How hot does New York City get in summer?
Summer in NYC runs warm and humid, with July and August seeing regular highs in the mid-to-upper 80s°F / 28–32°C. Heat waves can push temperatures above 90°F / 32°C. In 2025, June 24 hit 99°F / 37°C, breaking a record that had stood since 1888. The calendar shows every summer day in detail so you can see what you’re likely to walk into.
03
How humid does New York City get?
Humidity is one of the most underestimated aspects of New York summers, especially for visitors from drier climates. July and August regularly see humidity levels above 60–70%, which combined with heat in the upper 80s°F / 30s°C makes the air feel genuinely oppressive.
The humidity doesn’t just make you feel warmer. It slows your body’s ability to cool itself through perspiration. Visitors from the UK, northern Europe, or dry western climates are often caught off guard.
Light, breathable fabrics, staying hydrated, and planning for indoor breaks are essential summer strategies. September brings relief as humidity begins to drop, which is one reason early fall is so beloved by New Yorkers and visitors alike.
04
⚠️ Why does New York City feel so much hotter than the forecast says?
This is one of the most important things a visitor can know before arriving in summer. New York City experiences what scientists call the Urban Heat Island Effect. Research by the nonprofit Climate Central found that NYC has the most intense version of this effect in the entire United States.
The city’s built environment makes temperatures feel an average of nearly 10°F / 5.5°C hotter than the official reading, and some neighborhoods run 13°F / 7°C or more above the forecast.
Here’s why: millions of square feet of dark asphalt and concrete absorb heat from the sun all day, then slowly release it through the evening and into the night. Tall buildings create canyon-like streets that trap heat and block cooling breezes. Car engines, air conditioning units venting to the outside, and the subway system all add heat at street level.
The result: when the calendar says 88°F / 31°C, walking through Midtown or the outer boroughs can feel closer to 98°F / 37°C or more. Overnight lows that are supposed to bring relief often don’t. Nights in New York in summer are significantly warmer than the forecast low suggests, sometimes 15–20°F / 8–11°C warmer than suburban areas just outside the city.
Pack accordingly, stay hydrated, and build in time at air-conditioned museums, restaurants, and shops. Central Park, the High Line, and the waterfront offer real relief. Green spaces can run measurably cooler than the surrounding blocks.
05
⚠️ Why does New York City feel so much colder than the forecast in winter?
The same geography that makes New York a great city makes it a brutally cold one in winter, and visitors consistently underestimate it. Manhattan is an island. It sits between the Hudson River to the west and the East River to the east, with New York Harbor and the Atlantic Ocean to the south.
These open water channels create natural wind corridors that funnel cold air directly through the streets. The effect is amplified by the city’s canyon-like architecture. Rows of tall skyscrapers on either side of the avenues act like walls of a tunnel, accelerating wind speeds and concentrating cold air at street level in ways that have no equivalent in less densely built cities.
A forecast of 32°F / 0°C with a 20 mph / 32 km/h wind doesn’t feel like 32°F when you’re standing on a corner in Midtown. It feels like 17°F / −8°C. The long avenues running north-south, especially those closer to the rivers, are particularly brutal.
A good hat, a scarf that covers your face, and a genuinely warm coat, not just a stylish one, are essentials from late November through March. The calendar shows wind speeds for every day, giving you real data to plan around.
06
Does it snow in New York City?
Yes, typically from December through February, occasionally into March. Snowfall varies dramatically from year to year. In 2025, February 8 saw the heaviest single snowfall at 3 inches / 7.6 cm. Accumulation rarely lasts long in the city. Streets are plowed quickly and temperatures often bounce back above freezing within days.
That said, a fresh snowfall transforms New York into something genuinely beautiful, especially in Central Park. The calendar flags snow days so you can see at a glance when winter conditions were in play.
07
What are nor’easters and should travelers be concerned?
A nor’easter is a powerful storm system that moves up the U.S. East Coast, bringing heavy snow, rain, and high winds to New York City, typically between October and April. The name comes from the direction of the winds, which blow from the northeast.
These storms can be severe. A 2016 blizzard that dropped 27.5 inches / 70 cm of snow on Central Park was a nor’easter, but they are also well-forecast in advance. If one is approaching during your visit, you’ll have plenty of warning. The city is experienced at handling them, and the subway generally keeps running. Build some flexibility into travel plans during winter visits, particularly for flights in and out of JFK, LaGuardia, and Newark.
08
Is there a hurricane risk when visiting New York City?
Technically yes, but direct hits are rare. The Atlantic hurricane season runs June through November, with the greatest risk for New York City historically falling between August and October. Most Atlantic hurricanes weaken or change track before reaching New York, but the city is not immune.
Hurricane Sandy in 2012 caused significant flooding and damage, particularly in coastal neighborhoods. For most visitors, the risk is low enough that it shouldn’t deter travel, but if you’re visiting in September or October and a storm system is being tracked, it’s worth watching the forecast and having a flexible itinerary.
09
Does weather affect getting around New York City?
Rarely in a serious way, but it’s worth knowing. The subway runs in all weather conditions and is almost always the most reliable option during rain, snow, or extreme cold. Street-level transport, buses, taxis, and rideshares, slows considerably in heavy snow or rain.
Major blizzards can temporarily close some surface roads, but these events are announced well in advance. For air travelers, JFK, LaGuardia, and Newark are all susceptible to delays during nor’easters and significant snow events. Check conditions at your specific airport before traveling to it, especially in winter.
10
What should I pack for a trip to New York City?
That depends entirely on when you’re going, which is exactly what this calendar is for. Tap any day in your travel window and you’ll see the real high and low temperatures, wind speeds, and precipitation for those specific days in 2025.
New York weather can shift significantly even within a single month. As a general rule: summers call for light breathable layers and comfortable walking shoes; spring and fall require versatile layering as temperatures can swing 20°F / 11°C between morning and afternoon; winters demand genuinely warm outerwear, waterproof boots, and wind protection.
11
Is New York City worth visiting in winter?
Absolutely, but come prepared. January and February bring the coldest temperatures, typically ranging from the mid-teens to the low 40s°F / −10 to 5°C, with occasional snow. The tradeoff: fewer crowds, lower hotel rates, and the city at its most dramatic. The calendar’s deep violet and blue cards tell that story instantly.
12
What is the rainiest month in New York City?
Rain is fairly distributed throughout the year. NYC sees precipitation on roughly a third of all days. In 2025, July 14 was the single wettest day with 2.64 inches / 67 mm of rain. The calendar marks rain days with a precipitation indicator on each card so you can scan a month and get a feel for how wet it runs. A compact umbrella or a light packable rain jacket is worth carrying year-round.
13
How reliable is historical weather data for trip planning?
Very useful as a baseline, with the understanding that weather varies year to year. What you’re seeing in this calendar is what actually happened in 2025, a real year, not a statistical average. Paired with the all-time record highs and lows shown when you tap any day, it gives you a genuine sense of both typical conditions and what’s possible at any time of year.
