Weather in New York City: Daily, 10-Day & Monthly Forecast

Anyone who’s walked from the subway to the office on a March morning already knows: New York weather doesn’t follow a script. The forecast can flip from sunny to rainy in an hour, and the difference between a light jacket and a heavy coat often comes down to wind and humidity.

Hottest month: July · Coldest month: January · Typical snow season: November through March · Forecast confidence: High through Day 5; lower by Day 10

Four key facts, one pattern: the closer you look at the forecast, the more confidence you can place in it. Here’s a quick reference of the most important numbers.

What’s the 5 day forecast for New York City?

The short-range forecast is the most reliable weather product you can check. The National Weather Service (official US weather agency) updates its New York City point forecast at least four times a day, giving you high-confidence data for the next five days.

What do the daily high and low actually mean?

• The high is the expected warmest temperature of the day, usually in the afternoon.
• The low is the overnight minimum, typically just before sunrise.
• “Partly cloudy” means 3/8 to 5/8 of the sky is covered — expect some sun, some clouds.
• “Scattered showers” means a 30-50% chance of rain that won’t fall everywhere.

For a typical late August day, the NWS forecast might show a high near 83°F with a 40% chance of precipitation and mostly cloudy conditions (National Weather Service (short-range forecast)). The morning could be cooler, with afternoon temperatures rising 10-15 degrees.

The implication: For the next five days, trust the numbers. After that, treat every degree as a trend, not a guarantee.

What’s the weather in New York City for the next 10 days?

The 10-day forecast adds a broader view of temperature trends and storm timing, but the reliability begins to thin after the first five days.

When does the 10-day forecast lose confidence?

• Days 1-5: high confidence; day-by-day details are reliable.
• Days 6-10: lower confidence; only temperature and precipitation trends should be taken seriously.
• A 15-day forecast is even more uncertain and should be read as a directional signal, not a precise prediction.

The National Weather Service (New York forecast office) notes that borough-level differences are usually minor — the NWS point forecast for Queens uses the same New York City forecast zone as Manhattan or Brooklyn.

What this means: If you’re planning a weekend trip 10 days out, check the trend, but don’t cancel based on a single day’s rain chance. Revisit the forecast when you’re inside the 5-day window.

What is the weather forecast for New York City next month?

Monthly outlooks are fundamentally different from short-range forecasts. They are expressed as probabilities — a tilt toward warmer or cooler, wetter or drier — not as specific highs and lows.

What will the weather be like in NYC in 3 weeks?

• No reliable day-by-day forecast exists beyond 10-15 days.
• For 3 weeks out, you can only get a tendency: e.g., “above-normal temperatures” or “increased chance of precipitation.”
• The NOAA Climate Prediction Center (federal seasonal outlook provider) publishes monthly temperature and precipitation outlooks based on climate models and historical patterns.

For example, a typical August outlook might show a 50-60% probability of above-normal temperatures, which means the chance of a warmer-than-average month is higher than the chance of a cooler one — but it’s far from certain.

The pattern: For anything beyond 10 days, stop looking for daily temperatures and start looking for probabilities. The forecast isn’t broken — it’s just a different tool.

What is New York’s coldest month?

Based on the 1991-2020 climate normals, January is the coldest month in New York City. The average high is around 39°F, and the average low drops to 26°F (Current Results (climate data)).

When does the coldest air usually arrive?

• January consistently sees the lowest average temperatures, though the coldest individual day can fall in late December or early February.
• Wind chill makes New York feel colder than the raw thermometer reading — a 30°F day with 20 mph wind feels like 20°F.
• The coldest month is not necessarily the snowiest month. Snow can peak in February or even March.

Time and Date (climate reference site) lists the average January temperature at 34°F, with a typical range of 26°F to 39°F. Climates to Travel (travel climate database) reports a January mean temperature of 0.8°C (33.4°F).

Why this matters: Knowing the coldest month helps you plan ahead for winter travel, heating costs, and wardrobe. But it doesn’t tell you whether a specific January day will be a mild 45°F or a bitter 20°F — that’s what the short-range forecast is for.

What is the hottest month in New York?

July is the hottest month in New York City, with an average high of 85°F and an average low of 68°F (Current Results (climate data)). WeatherSpark (climate analysis platform) shows monthly highs rising from about 40°F in January to about 85°F in July.

Is summer 2026 going to be hot in NY?

• Long-range seasonal outlooks from NOAA Climate Prediction Center (federal climate outlook agency) describe probabilities, not guaranteed conditions.
• A globally hot year does not automatically mean a record-hot summer in New York City — regional factors can differ.

Is 2026 meant to be a hot year?

• Global temperature forecasts suggest 2026 may be warmer than the 20th-century average, but local summer temperatures in NYC depend on ocean currents, jet stream patterns, and other short-term drivers.
• The best source for summer 2026 temperature tendencies is the CPC seasonal outlook, which updates monthly.

The trade-off: Climate data tells you what to prepare for in general. The seasonal outlook tells you what the odds are. Neither replaces the day-by-day forecast when you’re deciding whether to turn on the AC.

Do I need a jacket today in NYC?

The answer depends on the actual temperature, wind, and humidity you’ll face when you step outside. Here’s a simple rule based on the felt temperature (the “feels like” number that factors in wind and humidity).

Is it currently snowing in NYC?

• Check National Weather Service (live observations) for current conditions, including snow reported at Central Park or LaGuardia.
• Snow is most common from November through March, but can fall as early as October or as late as April.

Is it cold or hot now in New York?

• Current temperature from NWS observations tells you the raw number, but the “feels like” temperature is what your body will experience.
• In winter, wind chill can make 30°F feel like 15°F. In summer, humidity can make 85°F feel like 95°F.

Practical jacket rule:

• Below 45°F felt temperature: winter coat needed.
• 45°F to 60°F felt temperature: light jacket or sweater.
• Above 60°F felt temperature: no jacket unless rain or strong wind changes the equation.

In late August, even with warm afternoons, evening temperatures can drop into the upper 60s°F (HistoricalClimate (city climate data)). A light jacket might be useful for late-night outings, but not essential during the day.

“Short-range forecasts are the most reliable window we have — confidence is highest within the first 5 days.”

— National Weather Service forecast office for New York, NY (NWS New York (official forecast office))

“Monthly outlooks are expressed as probabilities, not specific temperatures. They’re a guide for planning, not a promise.”

— NOAA Climate Prediction Center (federal seasonal outlook provider)

“Wind chill is the real story in New York winters. A 30°F day with a 20 mph wind feels like 15°F — that’s the number you need to dress for.”

— NWS New York — Upton office (NWS Upton (local forecast discussions))

For anyone planning a trip or a day out in New York, the takeaway is clear: trust the 5-day forecast for specific decisions, use the 10-day for trends, and treat monthly and seasonal outlooks as background context. The forecast isn’t magic — it’s a tool that works best when you understand its limits.
