Whether you're carving through waves or waiting for the next set, surfing is an intense full-body workout. It requires endurance, focus, and physical strength—all of which can be compromised if you're not properly hydrated. Many surfers underestimate how much water they lose while out in the ocean, thinking that the cool water can somehow substitute for what their body needs. The truth is, dehydration can sneak up on you, leading to fatigue, muscle cramps, poor reflexes, and even dizziness.
In this blog post, we’ll dive into why hydration is so crucial for surfers and provide you with practical tips on how to stay hydrated before, during, and after your surf sessions.
Why Hydration is Crucial for Surfers
When you're surfing, your body is in constant motion, whether paddling, duck-diving, or popping up on your board. All of these activities cause your body to sweat, even in cold water. While you may not feel it, you're losing fluids throughout the session. This is because being surrounded by water can mask the sensation of sweating, and the cool temperature of the ocean might make you think you're not overheating.
However, dehydration impacts your body's ability to regulate temperature, leaving you fatigued and less focused. For surfers, this can mean sluggish paddling, slower reactions to oncoming waves, and an increased risk of cramping—none of which is ideal when you’re chasing that perfect wave.
Signs of Dehydration in Surfers
Some key indicators that you might be dehydrated include:
Thirst (though by the time you feel thirsty, dehydration has already begun).
Dry mouth or lips.
Fatigue or sluggishness.
Dizziness or light-headedness.
Muscle cramps—common when paddling or after intense physical effort.
Reduced mental focus—slower decision-making and reaction times.
If any of these symptoms show up while surfing, it's a signal to take action to rehydrate as soon as possible.
Pre-Surf Hydration: Setting Yourself Up for Success
The hydration process starts long before you hit the water. Proper hydration should begin a day before a surf session, particularly if you plan to be out for extended periods or the surf conditions will be physically demanding.
Tips for Pre-Surf Hydration:
Start hydrating early: The day before surfing, make sure to drink plenty of water throughout the day. Aim for at least 2-3 liters, but you may need more depending on your body size and activity level. Typical recommendation is half your body weight in ounces.
Electrolytes matter: In the hours leading up to your surf session, include an electrolyte drink to replenish important salts and minerals like sodium, potassium, and magnesium. This helps maintain your body's fluid balance, especially if you tend to sweat a lot.
Eat water-rich foods: Hydrating isn’t just about liquids—eating foods high in water content can also help. Try snacking on fruits like watermelon, oranges, or cucumbers before you paddle out.
Avoid diuretics: Skip the morning coffee or energy drink right before surfing, as caffeine can increase fluid loss by promoting urination. If you need a pick-me-up, opt for a small coffee paired with plenty of water or a hydrating snack.
During-Surf Hydration: Staying Hydrated in the Water
While you’re in the ocean, staying hydrated can be a challenge. Most surfers don’t take breaks to hydrate until after their session is done, but if you’re planning to surf for more than an hour, it’s smart to bring water to the beach and take a quick break to sip.
Tips for Staying Hydrated During Your Session:
Take short hydration breaks: If your session lasts over an hour, paddle in for a short break to drink water. Keep a bottle of water or a sports drink on the beach for easy access between sets.
Listen to your body: If you start feeling thirsty, don’t ignore it. Paddle in, take a drink, and rest for a few minutes before heading back out. Staying hydrated ensures you’ll stay sharp and energetic throughout your session.
Post-Surf Hydration: Replenishing Lost Fluids
After a long session in the water, your body will likely be dehydrated, even if you don’t feel it right away. The combination of sun, wind, and saltwater accelerates fluid loss, so it’s essential to rehydrate as soon as you’re done.
Post-Surf Hydration Tips:
Rehydrate immediately: As soon as you’re out of the water, reach for a bottle of water or a rehydration drink. Aim to drink at least 500 ml (17 oz) right after your session and continue sipping water over the next few hours.
Electrolyte replenishment: After intense surf sessions, it’s not just water you need. Replenish your electrolytes with a balanced sports drink or coconut water. If you prefer whole foods, bananas, leafy greens, and nuts are excellent natural sources of electrolytes.
Hydrating foods for recovery: Pair your post-surf hydration with a snack rich in water content and nutrients. Think smoothies made with hydrating fruits like berries, coconut water, and chia seeds, or a simple salad with cucumber, leafy greens, and avocado.
Avoid alcohol post-surf: While it may be tempting to celebrate with a cold beer after catching some epic waves, alcohol dehydrates you further. Save the drink for later and make water your first priority after surfing.
Conclusion
Hydration plays a critical role in how you perform as a surfer. By staying properly hydrated before, during, and after your session, you can enhance your endurance, mental clarity, and recovery. Whether it’s an early morning session or a full day of chasing waves, remember that your hydration strategy is just as important as your surfing skills.
Next time you’re prepping for a surf session, make hydration a top priority—your body will thank you with better performance, more energy, and quicker recovery.
