How do you read a Beaufort scale?

How to read the Beaufort scale chart?

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.
7 — high wind, moderate gale, near gale.

Is 29 km wind strong?

20 to 29 km/h Strong enough to straighten flying flags and shake small tree branches. Expect dust and loose paper garbage to fly around in the air.

Is 23 knots windy?

19-24 Mph 29-38 kph 17-21 knots Fresh Breeze Small trees sway. White crested wavelets (whitecaps) form, some spray. 25-31 Mph 39-49 kph 22-27 knots Strong Breeze Large tree branches move, telephone wires begin to “whistle”, umbrellas are difficult to keep under control. Larger waves form, whitecaps prevalent, spray.
