How to Use the Wind Speed Risk Guide
Weather agencies typically issue a strong wind advisory around 14 m/s (about 31 mph) and a strong wind warning around 21 m/s (about 47 mph) of sustained wind speed. But a raw number doesn't always tell you how dangerous conditions actually feel, or whether it's safe to head outside.
Enter a wind speed value and unit (m/s, km/h, mph, or knots), and this tool converts it to m/s and classifies the perceived risk into four levels — safe, caution, danger, and extreme danger — along with specific safety guidance for each level.
Use it to decide whether it's safe to carry an umbrella, walk near signs or banners, or postpone outdoor plans for the day. Always check your local weather service's official warnings as well — this tool provides a general reference guide and is not a substitute for official storm alerts.
Frequently Asked Questions
No. This tool provides a general reference guide to perceived risk based on the wind speed you enter — always check your local weather service's official advisories and warnings before making safety decisions.
Sustained wind speed is the average over a period (usually 10 minutes), while gust speed is the strongest momentary burst during that period. Gusts are typically higher than sustained speeds and have a big impact on how dangerous conditions actually feel.
