How to read this page
How to read wind and category
Ian had maximum sustained winds of 259 km/h, category Category 5 on the Saffir-Simpson scale — a 1-to-5 scale based on wind alone.
Where this data comes from
Track and intensity come from HURDAT2, the NOAA National Hurricane Center’s historical storm catalogue.
What the category doesn’t tell you
Ian’s category measures wind alone. Rain, storm size and storm surge aren’t in it, and have killed more people than wind in recent hurricanes.
Words on this page
Saffir-Simpson category
A 1-to-5 scale that classifies a hurricane by its maximum sustained wind. From category 3 up a hurricane counts as "major", with significant structural damage expected; the scale ignores rain, size and storm surge, which can be deadly even at a low category.

Preliminary data
A measurement published as soon as it is collected, before the agency’s final review. It can be corrected or withdrawn: earthquake magnitudes shift in the first hours, air-quality readings are revised weeks later. Use it to plan your day, not for regulatory or legal purposes.

How to read these numbers
Track points come from HURDAT2, with position, wind and pressure every six hours. Rows marked as landfall are the moments when the centre crossed the coastline.
Frequently asked questions
- What category did Ian reach?
- The sheet shows the peak category, derived from the highest one minute sustained wind in the final reanalysis.
- Why is the death toll not shown?
- Deaths and damage come from narrative reports with varying methodology, not from the track database. We leave that number to the official source.
