New York City in the summer is vibrant, electric—and undeniably warm. From June through August, the city comes alive with outdoor events, park picnics, rooftop bars, and tourists snapping photos in Times Square. But with all that action comes a healthy dose of heat and humidity. If you’re planning a summer visit to the Big Apple, here’s what you need to know about the weather, what to wear, and how to stay cool while soaking up the city energy.
1. Temperature Overview: Warm Days and Mild Nights
Summer temperatures in NYC typically range from the mid-70s°F to the mid-90s°F (around 24°C to 35°C). While June starts off warm and pleasant, July and August are the hottest months.
Monthly Averages:
June: 75–82°F (24–28°C) during the day
July: 80–88°F (27–31°C) on average, with heatwaves possible
August: Similar to July but starts cooling slightly toward the end
Nights usually stay mild, with lows rarely dipping below 65°F (18°C).
2. Humidity: A Sticky Situation
Humidity is a big player in NYC’s summer weather. You’ll often find the air thick and muggy, especially in July and August.
Quick Tips:
Light, breathable clothing is essential
Stay hydrated—carry a reusable water bottle
Take breaks in air-conditioned spots like museums or cafés
3. Rainfall: Sudden but Short
Summer also brings occasional thunderstorms, especially in the afternoon or early evening. They’re usually quick bursts rather than all-day rain.
Be Prepared:
Pack a small travel umbrella or rain poncho
Wear shoes that can handle a surprise downpour
Check the forecast each morning—it can change quickly
4. Sunshine Hours: Long Days to Explore
With up to 15 hours of daylight in late June, summer is the perfect season for long, leisurely days of exploring.
Sunrise & Sunset:
Early June: Sunrise around 5:30 AM, Sunset around 8:20 PM
August: Days gradually shorten, but you’ll still get plenty of light
It’s ideal for early risers and night owls alike—sunlight sticks around for rooftop dinners and scenic river walks.
5. Air Quality: Mixed Bag
NYC air quality in summer can fluctuate, especially during heatwaves or high-pollen days. In general, it’s fine for most people, but those with respiratory sensitivities may want to check Air Quality Index (AQI) alerts.
6. What to Wear: Comfort is Key
You’ll want to dress for the heat and humidity—but remember that you’ll still be walking a lot, sometimes into chilly indoor spaces.
Packing List Must-Haves:
Breathable tops (cotton or linen are great)
Comfortable walking sandals or sneakers
Sunglasses, sunscreen, and a sun hat
A light cardigan or scarf for chilly subways and stores
7. Ways to Beat the Heat: Local-Style
Locals know how to stay cool when the mercury rises. Here’s how to keep your chill in the big city:
Smart Cool-Down Spots:
Public pools and splash parks (like in Central Park or Brooklyn Bridge Park)
Free libraries and museums with A/C
Icy treats from local shops (try a mango paleta or classic Mister Softee cone)
Take a ferry ride for cool breezes and views
8. Outdoor Fun: Summer in Full Swing
Despite the heat, summer is one of the best times to be outside in NYC. The city hosts festivals, concerts, and movies under the stars in every borough.
Can’t-Miss Events:
Shakespeare in the Park
SummerStage concerts
Smorgasburg food markets
Bryant Park movie nights

With the right wardrobe and a bit of weather smarts, you’ll be ready to embrace the warmth like a true New Yorker. So bring your sunnies, grab a slice of pizza, and make your way to the nearest park—because summer in the city is something special.
