How to read the lines. Each line is the track of one storm, drawn through its six-hourly positions and coloured by its intensity at each point (the Saffir-Simpson scale), so a line changes colour as the storm strengthens or weakens. Tap a line for its details, or tap anywhere else to see which storms have passed nearby. Weaker storms appear as you zoom in. Hurricanes, typhoons and cyclones are the same kind of storm with different names in different oceans.

What the record says

Olaf was a cyclone in the South Pacific and Australian region basin that lasted about 13 days, from 10 February 2005 to 23 February 2005. Its peak was Category 5 (145 kt) on 16 February 2005, with a 1-minute sustained wind of 145 kt (167 mph, 269 km/h). Its lowest recorded pressure was 915 hPa.

Source of the peak wind: US Joint Typhoon Warning Center (southern hemisphere). The regional forecast centre (RSMC Nadi (Fiji Meteorological Service)) gave a peak of 115 kt on its own averaging convention (10-minute winds), so the two figures differ.

It has its own page because it reached category 5 or stronger.

This page gives the official record's figures. It does not describe the human cost of the storm, which is far larger than any wind speed or pressure here.

Where it came ashore

How to read this track

The line joins the storm's six-hourly positions with straight lines, coloured by its intensity at each point, so it shows how the storm strengthened and weakened. The real path curved between the positions. A dashed grey stretch means the storm had become post-tropical. Records before the satellite era (about the 1960s) are estimates.
