What is the Haines Index?

The Haines Index is a tool used to assess the potential for wildfire. It combines temperature, relative humidity, and wind speed to provide a numerical value indicating the risk level.

How to Use the Calculator

  1. Enter the current temperature in degrees Celsius.
  2. Enter the current relative humidity as a percentage.
  3. Enter the current wind speed in kilometers per hour.
  4. Click the "Calculate" button to get the Haines Index result.

Interpreting the Results

The Haines Index ranges from 0 to 10, where higher values indicate a greater risk of wildfire. A value of 6 or higher is considered high risk.

Working Principle

The Haines Index is calculated by combining the effects of temperature, relative humidity, and wind speed. Higher temperatures and lower humidity levels increase the index, as do higher wind speeds. This reflects the conditions that are most favorable for wildfire ignition and spread.
