A clear breakdown of hurricane Categories 1 through 5, their wind speeds, storm surge potential, and real-world damage so you can gauge risk during the 2026 Atlantic season.

The Saffir-Simpson Hurricane Wind Scale ranks tropical cyclones that have reached hurricane strength into five categories based on maximum sustained wind speed. Category 1 starts at 74 mph; Category 5 begins at 157 mph. The scale estimates potential property damage but does not directly factor in storm surge, rainfall flooding, or tornado risk, all of which can be deadly regardless of category.
Civil engineer Herbert Saffir and meteorologist Robert Simpson developed the scale in the early 1970s to give emergency managers and the public a quick way to compare hurricane severity. The National Hurricane Center uses it today for every Atlantic and Eastern Pacific hurricane. The scale is purely wind-based: a Category 3 hurricane has sustained winds between 111 and 129 mph, regardless of how wide the storm is, how much rain it carries, or how high the surge will be. This is the scale's most important limitation. A slow-moving Category 1 can dump 30 inches of rain and cause catastrophic inland flooding, while a compact Category 4 can pass through with surprisingly little freshwater flooding.
Category 1 hurricanes produce very dangerous winds that will damage roofs, shingles, vinyl siding, and gutters. Large branches will snap, and shallowly rooted trees may topple, especially in saturated soil. Power outages typically last a few hours to several days. Hurricane Beryl in 2024 made landfall in Texas as a Category 1 and left over 2 million customers without power. Storm surge of 4 to 5 feet above normal tide levels is possible.
Category 2 storms are extremely dangerous. Well-constructed frame homes can sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted, blocking roads and taking down power lines. Near-total power loss is expected, and outages can last from several days to weeks. Hurricane Frances in 2004 was a Category 2 at Florida landfall and caused widespread damage across the state despite not being a major hurricane.
Category 3 is the threshold for a major hurricane. Devastating damage will occur: well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted. Electricity and water may be unavailable for days to weeks after the storm passes. Hurricane Sally in 2020 made landfall as a Category 2 but was a Category 3 just offshore, and its slow forward speed compounded rainfall flooding far beyond what the wind category alone suggested.
Category 4 hurricanes produce catastrophic damage. Well-built framed homes can lose most of the roof structure and exterior walls. Most trees and power poles will be downed. Power outages can last weeks to months, and the affected area may be uninhabitable for an extended period. Hurricane Ian in 2022 struck Fort Myers Beach, Florida, as a high-end Category 4 with 150 mph winds, destroying entire neighborhoods. Storm surge of 10 to 15 feet or more can sweep well inland.
Category 5 is the highest rating on the scale and means total destruction is likely. A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to months, and most of the affected area will be uninhabitable. Hurricane Michael in 2018 and Hurricane Andrew in 1992 both made landfall as Category 5 storms in Florida. Only four Category 5 hurricanes have made continental U.S. landfall in recorded history.
The Saffir-Simpson scale captures wind but leaves out three killers that often matter more.
When a real-time hurricane tracker shows a storm approaching your area, use the Saffir-Simpson category as a starting point, not the whole story. Check the NHC forecast cone for the projected intensity at landfall, then look at the separate storm surge warning zones and rainfall estimates. If your area is under a hurricane warning, follow evacuation orders regardless of the category number. A Category 1 can still be deadly if you are in a storm surge zone. Bookmark HurricaneHub to track storm intensity changes in real time and pair the category information with surge alerts, radar, and satellite imagery on a single map.

A Category 5 hurricane has maximum sustained winds of 157 mph or higher. This is the highest rating on the Saffir-Simpson Hurricane Wind Scale and indicates catastrophic to total destruction at landfall.
No. The scale is based solely on maximum sustained wind speed. Storm surge, rainfall flooding, and tornado risk are assessed separately. The NHC issues dedicated storm surge warnings because a low-category hurricane can still produce a deadly surge.
A major hurricane is any storm rated Category 3, 4, or 5 on the Saffir-Simpson scale, meaning sustained winds of at least 111 mph. Major hurricanes can cause devastating to catastrophic damage even though they represent only about a fifth of all named storms in a typical season.
