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.

The 2010s only run to 2013, so that bar is for a shorter period. This place's record starts in 1901, and records before the satellite era (about the 1960s) are far less complete.

Earlier decades hold fewer storms partly because they were harder to see. Before weather satellites (about the 1960s) many storms that stayed at sea went unrecorded, so compare decades with care.
