How Many Calories Does Surfing Burn?

Surfing calories by weight & duration

The approximately 211 calories per hour figure is a general estimate for someone weighing around 155 pounds, and your actual burn will shift based on your weight, how much time you spend actively paddling versus waiting, and the size of the surf. You can log your surf sessions and track how they fit into your broader activity picture using the Mariposas app.

Calculated as MET (3) × body weight (kg) × hours. How this works.

What to expect in a surfing class

Your first session will almost certainly start on dry land, where an instructor walks you through the pop-up, a move where you go from lying flat on the board to standing in one fluid motion. Expect to repeat that drill many times before you ever touch water, because muscle memory built on the beach translates directly to the lineup. In the water, you'll start on a wide, thick foam longboard in shallow whitewater (already broken waves), which gives you a forgiving surface and predictable conditions to practice timing your pop-up. Most beginners spend the majority of that first hour wiping out and paddling back into position, which is completely normal and, honestly, where most of the physical work actually happens.

Tips for your first surfing class

• Rent or borrow the biggest, thickest foam board you can find for your first several sessions. Stability beats style every time early on, and the extra volume makes it far easier to catch waves and practice your pop-up without constantly sinking.
• Practice the pop-up on the floor at home before you ever get wet. Place your hands flat under your shoulders, push up, and land with your back foot first, front foot second, sideways to the board. The order and timing matter more than people realize.
• Spend time just watching the break before you paddle out. Notice where waves are peaking, where other surfers are sitting, and where the water is moving. Reading that pattern even roughly will save you enormous amounts of paddling energy.
• Protect the back of your neck and ears from sun exposure, and wear surf-specific sunscreen rated for water resistance. The combination of salt water, reflection off the surface, and long time outdoors makes this one of the more sun-intensive activities you can do.

What affects how many calories surfing burns

The MET value of 3 reflects a moderate overall effort, but that figure captures an average that masks real variation. Time spent actively paddling out against whitewater, duck-diving under waves, and repeatedly jumping back on the board all push your heart rate up considerably, while the brief rides themselves are more stabilization than cardio. Because calorie burn scales with body weight and actual effort output, a heavier person paddling through larger surf will burn meaningfully more than the 211 cal/hr estimate for a 155 lb person, while a lighter person in gentle conditions will land below it.

Three things move your number most: body weight (a heavier body burns more for the same activity, that's why the table runs from 125 to 225 lb), duration (calories scale with time), and intensity. A surfing you push hard burns more than an easy one, because effort is what the MET value of 3 represents, an average for this activity. Your fitness level and how much you rest between efforts shift it too, so treat these as a solid estimate rather than an exact count.

How we calculate surfing calories

Every number here uses the standard energy-expenditure formula: calories ≈ MET × body weight (kg) × time (hours). The MET value of 3 for surfing comes from the published Compendium of Physical Activities, the same reference researchers and fitness trackers use. We convert your weight to kilograms and multiply through, no fudge factors. See our methodology for the full formula and sources.
