What you see

  • Each storm’s track as a thin line, with a natural-hazard dot at the point of its strongest winds.
  • Click one for its peak wind, its category, its basin and the time it peaked.
  • Opened from this page, the map plays 2000 to 2025.

Where the data comes from

  • IBTrACSNOAA NCEI’s International Best Track Archive for Climate Stewardship, version 4.01: the tracks of the world’s forecast agencies, merged.

IBTrACS adds storms as the agencies finish their best tracks; TAKIP takes them when the set is imported again.

Good to know

  • The dot marks where a storm peaked, often far out at sea; the line shows its whole path, landfall included.
  • Categories are the Saffir–Simpson scale on US agencies’ one-minute winds; storms without those winds (about half) have no category.
  • The Western North Pacific holds nearly a third of the storms; before satellites watched the oceans, weak storms far from ships and land were often missed.
