Frequently asked questions
What is the highest point in New Jersey?
High Point at 1,803 ft (550 m), from USGS, Elevations and Distances in the United States (highest and lowest elevations) (revised edition 2001).
What is the lowest point in New Jersey?
Atlantic Ocean, at sea level, per the USGS Elevations and Distances table (2001).
What is the average elevation of New Jersey?
About 218 ft (67 m): the mean of USGS 3DEP elevations at 233 points on a regular grid about 9 km apart inside the state boundary. It is our estimate, not a published figure.
Which New Jersey city on this site is highest?
Trenton, at 61 ft downtown (USGS).
Does altitude affect cooking in New Jersey?
At 218 ft, water boils at about 211.6 °F (99.8 °C) and standard air pressure is 29.69 inHg (1,005 hPa), so each breath holds about 99% of the oxygen it would at sea level. That is for the state's average elevation; check your own town, because New Jersey spans 1,803 ft from lowest to highest.
