- 0 — calm. Wind speed: < 0.5 m/s (< 1 mph).
- 1 — light air. Wind speed: 0.5–1.5 m/s (1–3 mph).
- 2 — light breeze. Wind speed: 1.6–3.3 m/s (4–7 mph).
- 3 — gentle breeze.
- 4 — moderate breeze.
- 5 — fresh breeze.
- 6 — strong breeze.

What does two Beaufort?
2. 4-6. Light Breeze. Small wavelets, crests glassy, no breaking. Wind felt on face, leaves rustle, vanes begin to move.
What is a force 4 wind?
noun – Force 4 is a moderate breeze on the Beaufort Wind Force Scale, an empirical measure for describing wind speed based mainly on observed sea conditions (on land it is categorized by the physical effects it has on vegetation and structures).
How strong is 10 knots wind?
| SPEED CONVERSIONS – KNOTS, MPH, KPH | ||
|---|---|---|
| Knots | Miles per Hour | Kilometers per Hour |
| 8 | 9.212 | 14.83 |
| 9 | 10.364 | 16.68 |
| 10 | 11.515 | 18.55 |
What is the highest number on the Beaufort scale of wind force?
The Beaufort scale, officially known as the Beaufort wind force scale, is a descriptive table. It depicts the force of wind by a series of numbers from 0 to 12. Actually, the Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons.
What is force 8 wind?
Modern scale
| Beaufort number | Description | Wind speed |
|---|---|---|
| 7 | High wind, moderate gale, near gale | 13.9–17.1 m/s |
| 8 | Gale, fresh gale | 34–40 knots |
| 39–46 mph | ||
| 62–74 km/h |
What is a Beaufort scale and how is it used?
The Beaufort scale is a scale for measuring wind speeds. It is based on observation rather than accurate measurement. It is the most widely used system to measure wind speed today. The scale was developed in 1805 by Francis Beaufort, an officer of the Royal Navy and first officially used by HMS Beagle .
What is measured on the Beaufort scale?
Beaufort scale. The Beaufort scale /ˈboʊfərt/ is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
What is the highest reading on the Beaufort scale?
The Beaufort scale, officially known as the Beaufort wind force scale, is a descriptive table. It depicts the force of wind by a series of numbers from 0 to 12. Actually, the Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons.
How does the Beaufort scale work?
The Beaufort scale is a method of estimating wind speed based on the general condition of the surface of a large body of water with respect to wind waves and swell. This scale allows sailors to estimate the wind speed just by observing the state of the sea surface.
