The entire available historic record of sea level and surface weather at Canton Island, Phoenix Islands, has been used to study linear relationships in the frequency range 0 to 0.8 cycles per day. Peaks in the sea-level spectrum at periods of four days and five days are strongly coherent with local weather, especially the meridional wind component. Thus the possibility that these oscillations are a manifestation of a global seiche is doubtful.
