Frequently asked questions
What is the highest point in Florida?
Britton Hill at 345 ft (105 m), from USGS, Elevations and Distances in the United States (highest and lowest elevations) (revised edition 2001).
What is the lowest point in Florida?
Atlantic Ocean, at sea level, per the USGS Elevations and Distances table (2001).
What is the average elevation of Florida?
About 60 ft (18 m): the mean of USGS 3DEP elevations at 245 points on a regular grid about 25 km apart inside the state boundary. It is our estimate, not a published figure.
Which Florida city on this site is highest?
Tallahassee, at 204 ft downtown (USGS).
Does altitude affect cooking in Florida?
At 60 ft, water boils at about 211.9 °F (99.9 °C) and standard air pressure is 29.86 inHg (1,011 hPa), so each breath holds about 100% of the oxygen it would at sea level. That is for the state's average elevation; check your own town, because Florida spans 345 ft from lowest to highest.
