Whittingham [11] has accepted the 29.1 and 27 inches reports from the Olive and the Crest of the Wave respectively seemingly unaware of the discrepant reports. He has estimated the track of the cyclone from the damage reports, placing it directly over the position of the Crest of the Wave. The Olive was to the north and missed the centre. A pressure there of 29.1 is consistent with that of the Crest of the Wave of 27 given the separation. He calculates the centre pressure, standardised for temperature, as 914 mb (hPa).[11]
In comparison tropical cyclone Tracy which devastated Darwin in 1974 had a central pressure of 950 hPa. Barometric pressure this low at mean sea level is also a likely cause and strong indicator of why cyclone Mahina created such an intense, phenomenal and claimed world record height storm surge of the likes not seen since.
