Highest hourly mean wind speeds were 68 knots (78 m.p.h.) at the Needles (Isle of Wight)
60 knots is the minimum speed for a wind aloft to be termed as a jet stream..
The main stem of a wind barb points in the direction that the wind is blowing from. The barbs show the wind speed to the nearest 5 knots. A half barb indicates 5 knots, a full barb indicates 10 knots, and a flag indicates 50 knots. To get the wind speed you add the numbers presented by the barbs. So, for example, if you have a full barb, and a half barb you ad 10+5 to get 15 knots. If you have a flag, 2 full barbs, and a half barb, you add 50+10+10+5 and get 75 knots. To convert to miles per hour multiply the wind speed in knots by 1.15. Wind speeds in mph are usually rounded to the nearest 5 mph as well. So 75 knots would be about 85 mph.These barbs can be found on many weather maps, not just hurricane maps.
Runway 14.
20 knots is 10.29 meters per second.
when the wind is like 20 knots + and the water is so choppy that it slows you down
20 to 25 knots
15 knots for student jumpers, 20 knots for professionals
Depending on your skill level anywhere between 5 knots and 20 knots. For someone that is just starting i don't recommend over 11 knots.
A wind of 64 to 71 knots is a hurricane force wind.
It really depends on the boat size and at what speed you want to sail. In just a light breeze the yacht will be moving and then as the wind increases strength the yacht will start going faster. I sailed a Vivacity 20 and a Halcat and this is what I experienced. Any other comments welcome.- AnonymousBelow 5 knots of wind there is not a lot of fun to be had, unless you are a fanatic or want to enjoy drifting!At 10 knots of wind things are pretty good for a beginner.At 20 knots of wind you need to be skilled and experienced and diligent.At 35 knots of wind there is a saying- you don't need a life jacket, you need a priest.Most kinds of races are cancelled if there is not at least 5 knots of wind at all the buoys.A lot of this is influenced greatly by the surf, boat and mood of the sailor.Cheers,- Rick "Your mileage will vary"

36 mph = 31.3 knots.
Knots.
20 knots = 37.04 kph
depends how windy it is surfing in big wind--poss 20 kts
It shows direction and wind speed in knots.
