There were no gages located north of Atlantic City. Visual observations 
made at localities north of Atlantic City included maximum heights of 10 
feet at Jones Beach, New York (1000 hours, 17 December), and at Cape Cod 
(Le Count Hollow) (1200 hours, 18 December). Volunteer observers report- 
ing by telephone on the 17th and CERC field crews out on the beaches on 
the 18th did not observe wave heights greater than 10 feet. 
DEMO COLM SUI Se. 
Tide data were examined from the following stations: Sandy Hook, New 
Jersey, Newport, Rhode Island, and Boston (Fig. 1). The predicted and 
measured tides for these locations on 16, 17, and 18 Decenber are shown 
in Figure 5. The greatest difference between predicted and measured tides 
at the three tidal gage stations occurred at Sandy Hook at 0400 hours on 
17 December. This was a storm surge of 3.6 feet. At Newport, the maxi- 
mum storm surge was 2.8 feet at 1000 hours on the 17th; at Boston, the 
storm surge was only about 2 feet, occurring early in the afternoon on 
ene 7a. 
Above normal tides at Sandy Hook lasted approximately 48 hours, from 
the beginning of the 16th to the end of the 17th. The duration of the 
elevated tides at the other two locations was about the same, but later 
in time. The maximum tides at Sandy Hook were about 1.5 feet higher than 
the springtides that occurred on the 12th and the 28th of December. Damage 
probably would have been greater had the storm occurred at the time of the 
springtides. 
3. Wave Direction. 
Estimates of the direction of breaking waves during the week of 13 
December at 12 localities between Cape Cod and Assateague Island are sum- 
marized in Figure 6. The average wave direction is expressed in a code 
diagrammed at the top of the figure. Because of the different orienta- 
tions of the beaches observed, direction relative to true north is not 
specified. The data indicate that waves were approaching the coast north 
of east before the passage of the storm, and south of east after the storm, 
which generally agrees with the wind patterns during that period. 
IV. BEACH SURVEYS 
1. Background. 
The effect of the storm was measured from surveys at the following 
seven BEP localities: In north-to-south order, Cape Cod, Massachusetts; 
Misquamicut, Rhode Island; Westhampton Beach and Jones Beach on the south 
shore of Long Island, New York; and Long Beach Island, Atlantic City, and 
Ludlam Island in southern New Jersey. The surveys were done by sur- 
veying crews from the U.S. Army Engineer Division, New England (Cape 
Cod and Misquamicut), and U.S. Army Engineer Districts, New York 
(Westhampton Beach and Jones Beach) and Philadelphia (Long Beach Island,
