If you’re hopping off a plane at JFK or catching the LIRR into the heart of Queens, the first thing that’s going to hit you isn’t the smell of street food or the noise of the Van Wyck Expressway. It’s the air. People talk about New York weather like it’s one big monolith, but honestly, the temperature in Jamaica New York has its own specific rhythm. It’s a place where the concrete holds onto the sun’s heat like a radiator in July, yet the wind whipping off the Atlantic can make a 40-degree morning feel like you’re standing in a walk-in freezer.
You’ve probably checked your phone’s weather app already. It says 75°F. You think, "Perfect, light sweater weather." But in Jamaica, that 75 degrees rarely feels like just 75. Between the humidity rising from the pavement and the way the buildings trap airflow, you’re looking at a microclimate that catches people off guard constantly.
Why the Numbers Lie About Summer
July in Jamaica is a beast. Technically, the average high sits around 83°F or 84°F. That sounds manageable, right? Kinda like a nice day at the park. But here’s the reality: Jamaica is a massive transit hub. You’ve got thousands of engines idling, black asphalt everywhere, and a humidity level that frequently pushes the dew point into the "uncomfortable" zone—above 65°F or even 70°F.
When the humidity is that high, your sweat doesn't evaporate. It just sits there. This is what locals call the "soup." On a day when the mercury says 90°F, the heat index—what it actually feels like to your body—can easily scream 100°F.
In June 2025, we saw a heat wave where temperatures at nearby Kennedy Airport hit record highs of 102°F. It wasn’t just the heat; it was the fact that the sun didn't really "turn off" at night. The buildings in Jamaica act like thermal batteries, staying warm long after sunset. If you’re visiting, don’t just pack for the temperature; pack for the moisture.
- Lightweight linen or cotton is your best friend.
- Synthetic "moisture-wicking" shirts work, but they can get a bit funky-smelling in the Queens humidity.
- Always carry a refillable water bottle; there are plenty of spots around the AirTrain station to top off.
The Winter Wind Tunnel Effect
Then there’s the flip side. January is officially the coldest month, with average lows hovering around 28°F. But the temperature in Jamaica New York during winter is dictated by the wind. Because Jamaica is relatively flat and close to the water, there’s nothing to stop those northern gusts from slicing through the streets.
I’ve seen days where it’s 35°F, but the wind chill makes it feel like 18°F. It’s a "wet cold." It gets into your bones.
If you're walking from the subway to a bus stop on Hillside Avenue, you’ll notice the locals aren't just wearing coats. They’re wearing "the uniform": a long puffer jacket that covers the thighs, waterproof boots, and usually a beanie pulled low. The slush is the real enemy here. Jamaica gets about 21 inches of snow a year on average, but it’s rarely the "pretty" kind. It’s the grey, salty slush that turns into a freezing puddle the second you step off a curb.
Spring and Fall: The Great Wardrobe Crisis
Honestly, shoulder seasons in Queens are a mess for your closet. You’ll wake up in April and it’s 45°F. By 2 PM, the sun is out, the temperature in Jamaica New York has climbed to 68°F, and you’re carrying your heavy jacket like a defeated soldier.
Basically, you have to layer. There’s no way around it.
- Morning: Light puffer or trench coat.
- Afternoon: Hoodie or denim jacket.
- Evening: Back to the coat.
May and October are arguably the best times to be here. The air is crisp, the humidity has retreated, and you can actually walk the length of Jamaica Avenue without feeling like you need a shower or a space heater. In May, the average high is a beautiful 71°F. It’s the kind of weather that makes the local parks like Rufus King Park actually usable.
Monthly Temperature Averages in Jamaica, NY
To give you a clearer picture without the "it depends" fluff, here is what the typical year looks like. These aren't just guesses; they're based on decades of National Weather Service data from the JFK and Central Park stations.
In January, the high is usually 39°F and the low is 28°F. It’s the peak of the "dark months." Moving into March, things start to thaw with a high of 50°F, but don’t be fooled—March is often one of the windiest months in Queens. By the time June rolls around, we’re hitting 80°F regularly. July and August are the heavy hitters, staying in the mid-80s during the day and rarely dropping below 69°F at night. September is the secret winner, with a pleasant 76°F high and lower humidity, making it the best time for travel. By November, the chill returns with a 54°F high, leading us back into the grey December days where the high averages 45°F.
What Most People Miss About the "Microclimate"
Jamaica isn't just a neighborhood; it's a bowl of concrete. If you look at a weather map, you’ll often see Jamaica is a degree or two warmer than the coastal parts of the Rockaways but cooler than the deep urban canyons of Manhattan.
Why? It’s the "Urban Heat Island" effect.
The dense concentration of tracks, buses, and retail buildings absorbs solar radiation. This means while your app says it’s cooling down at 6:00 PM, the street-level temperature in Jamaica New York might stay stagnant for another two hours.
Also, the proximity to JFK Airport matters. Large open runways allow for different wind patterns than what you’d find in a sheltered residential area like Jamaica Estates. If there’s a storm coming off the Atlantic, Jamaica often feels the brunt of the wind before it ever hits the rest of the city.
Staying Comfortable: Actionable Advice
If you want to survive the weather here without losing your mind, you need a strategy. This isn't just about checking the forecast; it's about knowing how to react to it.
First, download a weather app that shows "Perceived Temperature" or "RealFeel." In Queens, the raw number is almost irrelevant. If the dew point is over 65, prepare to be sticky. If the wind speed is over 15 mph in the winter, add an extra layer.
Second, think about your footwear. Jamaica is a walking neighborhood. In the summer, the pavement can literally reach 130°F. Thin-soled sandals are a mistake; your feet will cook. In the winter, if your boots aren't waterproof, you’re one "hidden slush puddle" away from a ruined day.

Third, check the "Air Quality Index" (AQI) during the summer. Because Jamaica is such a huge transit hub with high traffic, heat can trap pollutants near the ground. On 90-degree days, the air can get heavy, which is something to watch if you have asthma or other respiratory issues.
Final Logistics for Your Trip
If you are coming to Jamaica for a connection or a stay, the most important thing to remember is that the temperature in Jamaica New York changes fast. A "partly cloudy" day can turn into a torrential downpour in twenty minutes because of the way storms roll across Long Island.
Always keep a small, sturdy umbrella in your bag. The cheap $5 ones you buy on the street corner will flip inside out the second a gust hits you near the Sutphin Blvd station.
Keep an eye on the transition months—specifically late October and early April. These are the weeks where New York can't decide if it's summer or winter. You might see people in parkas walking right next to people in shorts. Neither of them is wrong; they just have different tolerances for the chaos that is Queens weather.
To prepare for your visit, check the current 7-day forecast from the National Weather Service rather than a generic global app. They have a station right at JFK that gives the most localized data for the Jamaica area. Pack layers, wear sturdy shoes, and don't let the humidity catch you by surprise.
Next Steps:
- Check the National Weather Service (NWS) forecast specifically for "Southern Queens" to get the most accurate wind chill or heat index data.
- If you're traveling during the summer, look up the nearest NYC Cooling Centers—many are located in local libraries around Jamaica Avenue.
- Invest in a high-quality, wind-resistant umbrella and waterproof footwear before arriving to handle the unpredictable Atlantic moisture.
