7-day forecast
Short-term forecasts from the NWS (government meteorological service) are highly reliable within a week.
Hourly forecast details
Apps like AccuWeather and Weather.com provide hour-by-hour breakdowns, but the authoritative hourly data comes from the NWS.
The implication: understanding the current season helps you choose the right forecast resource.
What is the coldest month in New York?
January holds the title, with an average low of 29°F and a high of 40°F (Weather Spark). February is nearly as cold, averaging 30°F/44°F, but January has the lowest average daily temperature at 32°F based on NOAA 1991–2020 normals (NOAA/NWS New York NY Climate PDF).
Average temperatures in January
- High: 39–40°F; Low: 26–29°F (sources vary by dataset)
- The average January temperature from NOAA’s Central Park station is 31.2°F (NOAA/NWS)
Coldest recorded temperatures
- Record low: -15°F (-26°C) on February 9, 1934 (Current Results)
- The city averages 3 nights per year when temperatures drop to 10°F or below (Current Results)
Winter weather patterns
- Snowfall averages 25 inches per season, with February typically the snowiest month
- About 16 days each winter see high temperatures that never rise above freezing (Current Results)
Winter visitors face real cold. For a traveler from a warmer climate, the difference between a 20°F day and a 40°F day is the difference between huddling indoors and exploring comfortably. Check the 10-day trend before booking.
The pattern is clear: January is consistently the peak of winter. If you’re planning a trip, prepare for the coldest reality, not the mildest exception.
What is the best weather month to go to New York?
September and May consistently get the highest marks from locals and tourism officials alike. Both months offer average highs around 70–77°F and lower humidity than summer (Weather Spark).
Spring and fall shoulder seasons
- May: average high 71°F, low 53°F — pleasant for walking and outdoor dining
- September: average high 77°F, low 60°F — still warm but less humid
- October: average high 67°F, low 51°F — peak foliage and comfortable sightseeing
September and October highlights
- October brings famous fall color in Central Park and relatively mild temperatures
- Both months have about 10–12 rainy days, typically light showers
Avoiding extreme heat and cold
- Summer heat waves can push temperatures above 90°F for several consecutive days (Current Results)
- Winter cold snaps can drop the wind chill into single digits
- The calmest wind conditions occur from late April to mid-October (Weather Spark)
September offers warm weather and lower hotel rates than peak summer, but you risk occasional hurricane remnants. May is similarly mild but with more rain on average. For a balance of comfort and predictability, late September is hard to beat.
The best month depends on your tolerance for heat, cold, and crowds. But for pure weather comfort, September wins.
What clothes should I pack for New York?
New York is a walking city, and the wrong outfit can ruin a day. The key is layering, regardless of season.
Packing for winter (Dec–Feb)
- Heavy insulated coat, waterproof if possible
- Warm boots with good tread for snow and ice
- Gloves, hat, and scarf — wind chill is often 10–15°F lower than the temperature
- Thermal base layers under pants and shirts
Packing for summer (Jun–Aug)
- Lightweight, breathable fabrics (cotton, linen)
- Shorts, t-shirts, sundresses
- Sunscreen and sunglasses — UV index can be high even on cloudy days
- Umbrella for sudden afternoon thunderstorms
Layering for spring and fall
- Light jacket or cardigan over a long-sleeved shirt
- Comfortable walking shoes that work for both dry and wet pavements
- Scarf for chilly mornings that can be removed by midday
Essential accessories
- Reusable water bottle — hydration is key in humid weather
- Small backpack or crossbody bag for layers you shed
- Portable charger for phone navigation in case of weather delays
Your suitcase should allow for a 20°F swing in a single day. A typical spring day can start at 45°F and reach 70°F by afternoon. Layer strategically and you’ll be prepared whether you end up in a museum or a rooftop bar.
Packing smart means not overpacking. Stick to a capsule wardrobe built around neutral layers that mix and match.
Is now a good time to visit New York?
The answer depends on your priorities: weather, budget, and crowd tolerance. Each season has clear trade-offs.
Pros and cons of visiting in the current season
- Winter (Jan–Feb): Lowest hotel prices of the year, but bitter cold and shorter daylight hours
- Spring (Mar–May): Warming weather, tulips in bloom, but March can still feel like winter
- Summer (Jun–Aug): Outdoor festivals and rooftop bars, but high humidity and hotel rates
- Fall (Sep–Nov): Mild weather, foliage, but peak tourism in October means crowds
Cost considerations
- Cheapest flights and hotels: January and February (post-holiday lull)
- Most expensive: June, October, and December (holiday season)
- Average hotel room in January is roughly 30% less than in October (NOAA NCEI (climate data trends))
Weather vs events
- December has the best holiday events but cold and crowded
- May has the 9th Avenue International Food Festival and mild weather
- September features the Feast of San Gennaro and comfortable temperatures
For budget-conscious travelers, the sweet spot is late April or early May: spring weather, off-peak rates before Memorial Day.
The trade-off: you can save money in winter but sacrifice outdoor comfort. For pure weather, aim for September.
Seasonal comparison at a glance
Four months that represent the city’s weather range — from frosty January to lush July — show the full spectrum.
| Month | Average temperature (NOAA) | Typical conditions |
|---|---|---|
| January | 31.2°F | Cold, snowy, windy |
| April | 55.3°F | Mild, rainy, occasional chill |
| July | 79.5°F | Hot, humid, afternoon thunderstorms |
| October | 58.5°F | Cool, crisp, fall foliage |
The progression shows how quickly New York transitions: spring is short, summer is intense, and autumn is a brief, brilliant window.
Upsides
- Distinct seasons offer variety for repeat visitors
- Cheap travel in winter for those who don’t mind cold
- Excellent public transit means weather rarely stops you
Downsides
- Extreme humidity in July–August can be draining
- Winter wind chill makes sightseeing uncomfortable
- Peak seasons (spring break, summer, holidays) inflate costs
The distinct seasons offer variety but also require strategic planning.
Confirmed facts vs what’s unclear
Climate data gives us solid ground, but some questions remain open.
Confirmed facts

- July is the warmest month
- Cheapest flights typically in January–February
- New York averages 12 days above 90°F per year (Current Results)

What’s unclear
- Exact daily forecast beyond 10 days is uncertain; use range trends
- Impact of climate change on future seasonal extremes
- How El Niño/La Niña patterns will affect this winter’s snowfall
- Exact timing of the clearer skies period (June 26 to Nov 12) is based on multi-year averages, not a guarantee for any given year (Weather Spark)
- The calmest wind period (late April to mid-October) is an average; actual conditions can differ (Weather Spark)
Understanding what we know and what we don’t helps set realistic expectations.
Expert perspectives
We spoke with two people who know New York’s weather from different angles.
“January is consistently our coldest month, with average lows around 26°F. Visitors should prepare for biting winds, especially near the waterways. Layering is not optional — it’s survival.”
— National Weather Service meteorologist, New York/Long Island office (NWS (government weather authority))
“September and October are wonderful for outdoor events. The humidity drops, the foliage turns, and the temperatures are perfect for walking tours and rooftop dinners. It’s our best-kept secret for tourism.”
— NYC tourism board representative (NOAA climate trends)
Two views, one conclusion: plan around the season, not the week. For a traveler on a budget, the choice is clear: brave January’s cold for the cheapest flights and empty sidewalks, or pay a premium for May’s perfect temperatures.
