The ideal helmet will, of course, vary from one surfer to another, depending on performance level, age and size. This being said, there is a basic criteria in which every safety helmet should satisfy. Below, we have put together a small guide of the sorts of factors you should be considering when looking for the perfect, protective surfing helmet.

The fit of your surf helmet can make an enormous difference to the quality of its protection. A well-fitted helmet should cover your entire head, extending horizontally over the top of your forehead. This is not only essential in the protection of impact to your face but to protect you from direct sunlight exposure, which in extended periods, can be dangerous.

Whilst many brands of helmets will offer a wide range of sizing options, many will be more reliable on self-adjustment which is something to keep in mind. When buying your helmet you should be given a size guide which you can compare against your head tape-measurement. These guides should give you an accurate indication of what size to choose. If you are still unsure, it can be helpful to check the ‘customer reviews’ for comments that discuss sizing to get a better idea.


The design and construction of a surf helmet with vary with most brands and suppliers. Most, are built upon a serious of layered materials that are constructed with your safety and comfort in mind.

The outer shell of the helmet is what will absorb the impact energy. It is usually constructed of tough, resistant plastic which distributes the impact energy through the entire shell. This outer shell is what protects your head from the brunt of high-impact, blunt force.

Inside the exterior shell, you will typically find a tough, but comfortable non-water absorbent foam. Together, both layers work to prevent any sort of damage from aquatic activity. When buying a helmet, you should always check whether the product complies with the current helmet safety standards.


When it comes to surf helmets, you want something that is going to be tough and durable enough to protect, whilst being light and portable enough to be transportable and non-imposing. Wearing a surf helmet that’s too heavy can cause an imbalanced body posture which can hinder your surfing abilities and possibly, cause you to fall. With this in mind, it is best to look for a low-profile, lightweight helmet.


Whilst the aesthetic appearance of a surf helmet shouldn’t be a top priority. The color of the helmet is actually a lot more important than you may think. Whilst dark-colored helmets may look sleek, vibrant colors of yellow, orange or bright green are a much better option in terms of making you stand out in difficult or busy conditions. Especially if you are looking for a younger surfer, we would recommend considering going for the brighter as it means they will be much more visible if there were to be an emergency.

Ear Protection

When looking for the right surf helmet, you should look for the models that offer ear covers for optimal protection. The more desirable helmets will have adjustable ear coverings that can be extremely beneficial when it comes to a change in the weather or temperature.


Whilst, all of our top picks are of a reasonable price, the surf helmet market is built up of a wide range of priced helmets ranging, from between $20 to $200. Whatever your budget, you will be able to find something that suits you. Just keep your safety in mind when making your decision.

Best Surf Helmets - FAQ's

How much can a helmet really protect me?

Whilst the helmet won’t protect you from injuries of the neck, spine, or extremely high impact collisions, it will minimize the severity of head injuries. Because the helmet is providing an additional layer for the head, it reduces the risk of severe injury by absorbing most of the impact energy.

Can surf helmets be used for other water sports other than surfing?

Well, whilst these surf helmets can also be used for other water sports such as water skiing, wakeboarding, windsurfing, and Kayaking, some models may be more suited to specific sports. You may want to check with the individual products, but the surfing helmets are generally designed to suit all water-based activities.

When should the helmet be used?

Ideally, the helmet should be used at all times when surfing, especially if you are a younger or less experienced surfer. Although it is not a legel requirement, due to the severity of head injuries that can be caused by surfing, it is not worth the risk to go without.

How do I store and care for my helmet?

Most helmets will come with a protective storage bag or box. Whilst you can and are often encouraged to decorate your helmet with reflective stickers, you should not paint your helmet in any way. You should keep your helmet out of direct sunlight and store it somewhere that doesn’t get too warm.
