Choosing a minimum category hides storms with no wind speed in the record. To see which storms have passed near you, search a town or ZIP code, or tap the map.

Key
  • Tropical depression Winds below 34 knots (39 mph)
  • Tropical storm 34 to 63 knots (39 to 73 mph)
  • Category 1 64 to 82 knots (74 to 95 mph)
  • Category 2 83 to 95 knots (96 to 110 mph)
  • Category 3 96 to 112 knots (111 to 129 mph), major
  • Category 4 113 to 136 knots (130 to 156 mph), major
  • Category 5 137 knots (157 mph) or more, major
  • Unknown intensity No wind speed in the record
  • Post-tropical Storm has become post-tropical (dashed line)

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 2020 season in numbers

The record holds 21 storms for the 2020 Eastern and central Pacific season, of which 16 had names.17 reached tropical storm strength (34 knots or more), 4 reached hurricane strength (category 1 or more) and 3 were major (category 3 or more).

  • 21storms
  • 17tropical storm strength or more
  • 4hurricane strength or more
  • 3major (category 3 to 5)
  • 77accumulated cyclone energy

Accumulated cyclone energy adds up the squared wind speed of every position of 34 knots or more, divided by 10,000. It is approximate here because the winds are 1-minute equivalents, and it is mostly useful for comparing seasons of one basin.
