What Are the Warmest Cities in New Jersey?
KEY TAKEAWAYS
The three warmest cities in New Jersey are Moorestown, Atlantic City, and Newark.
In this article I’m going to share with you my ranking of the warmest places in New Jersey.
I created my list by researching data provided by the National Oceanic and Atmospheric Administration and other climate data providers.
Below I’m listing the top 10 warmest places in New Jersey that have the highest average yearly temperatures. Later in the article I share a table with 50 most populous cities in the state.
Top 10 Warmest Cities in New Jersey
Here are the top 10 warmest places in New Jersey ranked by their daily mean temperature. Note that the cities on this list all have at least 15,000 inhabitants. The warmest place in New Jersey would be the small resort town of Cape May, with an annual daily average temperature of 56.2 °F (so only slightly higher than Moorestown). New Jersey’s climate isn’t warm but the cities in the top 10 offer a milder climate than other cities in the state.
1. Moorestown – daily mean temperature of 55.8 °F
A suburb of Philadelphia, the township of Moorestown, is the warmest city in New Jersey. It has an average annual daily mean temperature of 55.8 °F. Average temperatures in the coldest months hover between 43-47 °F during the day and drop to 26-31 °F at night. Freeze free days last between March and November. Summers bring hot weather, with temperatures reaching on average 84-88 °F in the hottest months.
2. Atlantic City – daily mean temperature of 55.5 °F
Atlantic City, New Jersey’s most well-known coastal resort town located on the Atlantic Ocean, is the second warmest city in the state. Atlantic City offers a less extreme climate than Moorestown, with lower differences between average maximum temperatures and average minimum temperatures. This means much more pleasant summer months with temperatures no higher than 80 °F on average. Atlantic City offers some of the mildest winter conditions in the state, too. While daily highs are a degree lower than in Moorestown, temperatures at night drop below freezing only in January and February (compared to December to February in Moorestown). Ocean City, located in the same area, has virtually the same climate.
3. Newark – daily mean temperature of 55.45 °F
Newark, the most populous city of the Garden State, is the third warmest city in NJ and the warmest big city. Its average annual temperature is just slightly lower than in Moorestown. The difference is particularly visible during the day. Winter highs are 40-45 °F compared to 43-47 °F in Moorestown. Summer days are also slightly cooler. Newark offers warmer nights, though (but not as warm as in Atlantic City). Average annual precipitation ranges and the average number of rainy days in both Atlantic City and Newark are roughly the same.
4. Voorhees Township – daily mean temperature of 55.05 °F
Voorhees Township is located about 10 miles south of Moorestown. It has a very similar climate with summers that are about a degree cooler. The average number of sunshine hours is about 2,500 hours.
5. Cherry Hill Township – daily mean temperature of 55 °F
Cherry Hill Township is another township located in the same suburb area of Philadelphia. The difference between Cherry Hill and the previous townships is that Cherry Hill has slightly lower average temperatures at night.
6. Camden – daily mean temperature of 55 °F
Camden is a city located directly across the Delaware River from Philadelphia, Pennsylvania. As other locations in this area, it shares virtually the same climate with mild winter weather and hot summers.
7. Hoboken – daily mean temperature of 55 °F
Hoboken is a city located on the Hudson River, right by the border with New York State. It has lower winter daytime temperatures than the previous cities (highs between 38-43 °F) and cooler summers with temperatures between 79-84 °F.
8. Glassboro – daily mean temperature of 54.95 °F
For a change, Glassboro is the first city on this list not located close to any large bodies of water. It’s situated about 20 miles south of Camden and features weather like Cherry Hill Township and other cities in the area.
9. Harrison – daily mean temperature of 54.8 °F
Harrison is located directly across the Passaic River from Downtown Newark. Due to being just two miles away, it features almost exactly the same climate, with slightly cooler nighttime temperatures.
10. Hammonton – daily mean temperature of 54.6 °F
Hammonton is located roughly halfway between Camden and Atlantic City and is the most inland city in this ranking. If you’re looking for one of the warmest areas in New Jersey that isn’t heavily urbanized, Hammonton is your best option. It’s located near Wharton State Forest, the largest state forest in New Jersey.
50 Biggest Cities in New Jersey Ranked by Daily Mean Temperature
