The 1935 Hurricane (it had no name) was much more powerful.
The 1935 storm had a minimum central pressure of 892 millibars, Camille was measured at 902....not quite as low, but close enough for government work.
The maximum sustained wind speed at landfall is estimated to have been near 160 mph (260 km/h). However, recent reanalysis studies conducted by the NOAA Hurricane Research Division (HRD) suggest that the maximum sustained winds were more likely around 185 mph (295 km/h) at landfall.
From Wikipedia re Camille:
Camille was the strongest landfalling tropical cyclone recorded worldwide, and one of only four tropical cyclones worldwide ever to achieve wind speeds of 190 miles per hour (310 km/h).
the 1935 hurricane never struck the “mainland”..it clipped the Florida Keys. Hurricane Camille is still the the most powerful storm of any kind to ever strike the mainland of the United States. A wind recording device failed and stuck at 172 m.p.h at Boothville, La...and that was on left quadrant side, usually the weakest side. One ocean going vessel recorded a gust of 237 m.p.h. Also, Camille’s barometric pressure was the lowest ever recorded that far north of the equator. Its thought that the storms very rare small size contributed to the astounding wind speeds that were seen. Survivors all say that the sound of the storm was unbelievable....truly a bench mark storm.
