Why wind units matter
Different forecast platforms and regions use different wind speed units. Kitesurfers often see knots in marine forecasts, meters per second in parts of Europe, kilometers per hour in general weather apps and miles per hour in the US or UK. This converter helps you read any forecast quickly and compare conditions before choosing your kite size.
What wind speed do you need to kitesurf?
Most twin-tip riders start having reliable sessions from around 14 to 16 knots, depending on rider weight, board size, kite size and skill level. Light wind riding below that usually requires larger kites, bigger boards or foil equipment. Above 25 knots, conditions become more physical and require better kite control, smaller kites and conservative decision making.

Beaufort scale for kitesurfers
| Bft | Name | Knots | Kitesurfing |
|---|---|---|---|
| 0–1 | Calm | 0–3 kts | No kitesurfing |
| 2 | Light breeze | 4–6 kts | Not enough for normal kitesurfing |
| 3 | Gentle breeze | 7–10 kts | Light-wind specialist conditions |
| 4 | Moderate breeze | 11–16 kts | Beginner to freeride range with larger kites |
| 5 | Fresh breeze | 17–21 kts | Excellent freeride conditions |
| 6 | Strong breeze | 22–27 kts | Powered riding, smaller kites |
| 7 | Near gale | 28–33 kts | Advanced riders only |
| 8+ | Gale conditions | 34+ kts | Dangerous for most riders |
How the conversion works+
1 knot = 0.514444 m/s
1 knot = 1.852 km/h
1 knot = 1.15078 mph
m/s → knots: knots = m/s × 1.94384
km/h → knots: knots = km/h ÷ 1.852
mph → knots: knots = mph ÷ 1.15078
Beaufort is approximated from knots using standard wind speed ranges.
Frequently asked questions
What is the difference between knots and km/h?+
Knots are commonly used in marine and wind forecasts. One knot equals 1.852 km/h.
Why do kitesurfers use knots?+
Knots are standard in many wind, marine and aviation forecasts, which makes them useful for comparing kitesurfing conditions globally.
How many knots do I need to kitesurf?+
Many freeride twin-tip riders need around 14 to 20 knots, depending on weight, kite size, board size and skill level.
Is 20 knots good for kitesurfing?+
Yes, 20 knots is a strong and useful freeride wind range for many riders, but kite size and rider level matter.
What Beaufort is good for kitesurfing?+
Beaufort 4 to 6 is often relevant for kitesurfing. Beaufort 5 is usually a very good freeride range.
Is Beaufort accurate enough for kite size?+
Beaufort is useful for general understanding, but kite size should be chosen based on actual wind speed in knots, rider weight, board type and local conditions.
This converter is for quick wind speed reference only. Always check local forecasts, gusts, wind direction, weather changes and local spot conditions before kitesurfing.
