Calories burned
windsurfing or kitesurfing

809 kcal / hour Windsurfing or kitesurfing burns approximately 809 calories per hour for a 70 kg (154 lb) adult, and 404 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 578 to 1,386 kcal.

It carries a MET value of 11 in the 2024 Adult Compendium of Physical Activities.

Calories burned windsurfing or kitesurfing by body weight

Energy cost scales with the mass you move, so body weight changes the answer more than anything else.

What 809 calories an hour actually means

At MET 11, windsurfing or kitesurfing counts as very vigorous activity — it uses about 11 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 13 kcal per minute, or 809 kcal across a full hour.

Within water activities, that ranks 3rd of 29 activities by energy cost, a little below skindiving (MET 11.8) and above water polo (MET 10).

Put differently: one hour of windsurfing or kitesurfing costs about the same energy as 165 minutes of ordinary walking.

On the food side, a plain bagel (about 245 kcal) takes roughly 18 minutes of windsurfing or kitesurfing to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.

Questions

How many calories does windsurfing or kitesurfing burn per hour?

About 809 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 11. A 90 kg adult burns closer to 1,040 kcal in the same hour, because energy cost scales almost directly with body mass.

How many calories does 30 minutes of windsurfing or kitesurfing burn?

Roughly 404 kcal at 70 kg, 347 kcal at 60 kg and 578 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.

What is the MET value of windsurfing or kitesurfing?

11. One MET is the energy you use sitting quietly, so MET 11 means 11 times that rate.

Is this an exact number of calories?

No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.

MET value from the 2024 Adult Compendium of Physical Activities (activity code 18385). Calories computed as MET × 3.5 × weight kg ÷ 200 per minute. General information only — not medical, fitness or nutrition advice. Calorie figures are population estimates and vary between individuals.
