Saffir-Simpson Scale Calculator
About the Saffir-Simpson Scale Calculator
The Saffir-Simpson Scale Calculator is a scientifically accurate, real-time online tool that instantly determines the official Saffir-Simpson Hurricane Wind Scale category (1–5) based on sustained wind speed, and provides detailed expected damage, storm surge, and impacts according to the National Hurricane Center (NHC/NOAA) standards. Developed by Herbert Saffir and Robert Simpson, the scale is the global benchmark for classifying tropical cyclones in the Atlantic and Northeast Pacific basins. This calculator strictly follows the current NOAA/NHC definitions (updated 2012), delivering trustworthy results for meteorologists, emergency managers, coastal residents, insurers, and agricultural planners monitoring hurricane threats.

Importance of the Saffir-Simpson Scale Calculator
The Saffir-Simpson scale provides a clear, standardized way to communicate hurricane intensity and expected damage to the public. Category 3+ storms are considered “major” hurricanes capable of devastating impacts. Accurate category determination drives evacuation decisions, insurance claims, building codes, and agricultural preparedness. In farming regions, even Category 1 hurricanes can destroy orchards, flood fields, and contaminate soil with saltwater surge. Stronger storms strip foliage, snap trees, and cause prolonged power outages affecting irrigation pumps and cold storage. This calculator instantly translates wind speed reports into official category and damage outlook, enabling timely protective measures promoted by Agri Care Hub.
Purpose of the Saffir-Simpson Scale Calculator
Core functions:
- Convert sustained wind speed (knots, mph, km/h, m/s) to official category 1–5
- Display NOAA expected damage description, storm surge range, and typical impacts
- Provide agricultural and infrastructure risk guidance
- Highlight when a storm becomes “major” (Cat 3+)
When and Why You Should Use It
Use this tool when you:
- Track an approaching hurricane and need official category from reported winds
- Plan evacuation or crop protection measures
- Assess potential damage to farms, greenhouses, or orchards
- Educate others about hurricane intensity scales
Official Saffir-Simpson Hurricane Wind Scale (NOAA/NHC)
| Category | Sustained Winds | Damage Description |
|---|---|---|
| 1 | 74–95 mph (64–82 kt) | Some damage to trees, power outages |
| 2 | 96–110 mph (83–95 kt) | Extensive tree damage, prolonged outages |
| 3 (Major) | 111–129 mph (96–112 kt) | Devastating damage, many structures destroyed |
| 4 (Major) | 130–156 mph (113–136 kt) | Catastrophic damage, most trees down |
| 5 (Major) | ≥157 mph (≥137 kt) | Catastrophic, complete roof failure on many buildings |
Note: The scale is based on 1-minute sustained winds at 10 m height.
