Alright, so picture this: you’re ready to dive into the big blue, all set to explore its glory to the fullest. But hold up, you have to lube up and get into that dreaded neoprene wetsuit first. A real turn-off for some.
What if I told you that you could ditch that clingy neoprene sausage casing and dive in au naturale? Yep, you heard me right – scuba diving without a wetsuit! Is diving feet first into the blue depths without a wetsuit recommended, or even possible?
It is indeed possible to scuba dive without a wetsuit if you’re diving in warm waters, and are careful enough to not brush yourself against fire corals or the sting of hydroids and jellyfish.
There’s a small hiccup: the chafing caused by the rest of the scuba accessories constantly rubbing against your skin might ruin the dive experience.
But, don’t worry just yet, I have the perfect game plan devised for those of you willing to take a daring no-wetsuit dive and that includes tips to get rid of the dreaded skin chafing. So stick to the end of the post.

Is Diving without A Wetsuit Safe?
To answer your safety concerns we have to gloss over the wetsuit basics first. What is the primary function of your wetsuit? It is to regulate your body temperature in cold waters by trapping a layer of water in the space between the neoprene and your skin which gets warmed up by your body temperature which is 37°C (97°F).
Body Temperature Regulation
Diving without a wetsuit leaves your body more prone to heat dissipation in your marine surroundings. In simple words- you feel cold faster than you would with your wetsuit on. But this scenario is mostly prevalent in cold waters.
If we take the cold water out of the equation, the primary requirement of a wetsuit is taken care of. If you’re taking a standard 45-minute rec dive in tropical waters, where the water temperature rarely goes below 30°C (86°F) there isn’t any need for a wetsuit to keep you warm, the warm water around you will keep your body temperature in check.
Diving in warm waters without a wetsuit is no different than taking an hour-long swim in a well-warmed swimming pool from a body temperature regulation perspective.
Your Bare Skin Is Exposed to Marine Elements
We’re not in the clear waters yet, regulating your body temperature isn’t all there is to your wetsuit. Wetsuits also offer a certain degree of protection against jellyfish stings, coral reefs, serrated rock edges, and urchins.
Warm tropical waters come with their fair share of creatures that are simply too trigger-happy (stinger-happy I mean) like jellyfish, hydroids, sea urchins, fire corals, and stone fishes to name a few. Then there are the jagged rock formations that make it fairly easy to get a deep gash on your skin if you’re not careful enough.
So, even while diving in tropical waters check in with the local dive shop or study beforehand about the marine conditions. If you’re planning to dive in a location that is a hub of Portuguese man o’ wars or is rife with high-rise fire corals, it’ll be difficult to dive without a wetsuit but still manageable.
Research suggests that using a jellyfish repellent reduces the risk of getting stung by ~80%. Hence, the jellyfish situation can be easily mitigated if you rub dollops of Safe Sea SPF50+ Jellyfish topical repellent lotion to keep those little stingers at bay. These topical repellents confuse the jellyfish into thinking you’re one of them, making it less defensive around you.
As for the coral situation, I’m afraid there’s no underwater life hack to get around it. You simply have to be cautious and try to keep your horizontal stance throughout the dive to avoid getting your legs accidentally brushing off the reefs. Even a wetsuit doesn’t warrant brushing against the delicate reefs from a marine conservation standpoint.
Skin Chafing Issues
Now to the actual nuisance. Chafing can happen even when you’re wearing a wetsuit if it’s too tight. The severity of chafing increases tenfold when you’re bare-skinned. The constant brushing and rubbing of the dive gear especially your dive tank on your skin can cause blisters or rashes to develop on the affected area and by no means is it a pleasant experience.
The common workaround for the chafing situation is to wear a shorty, rashguard, or a sleeveless lycra dive vest like the Dizokizo Thermal Sleeveless Neoprene Vest. During deeper and colder dives I tend to wear this underneath my wetsuit and it has worked like a charm so far.
Pretty neat and effective solution but let’s take it up a notch by incorporating my simple twist. Learn diving with sidemount tank configuration.
Sidemount configuration involves tucking your tanks behind your armpits and the skin contact is perpendicular to gravity hence less severe sideways. Whatever residual chafing occurs around your obliques is taken care of by the dive vest.
Buoyancy Compensation for The Lack of Wetsuit
Not wearing a wetsuit will lower your overall weight which in turn will affect your neutral buoyancy to some extent. You need to offset this lack of your wetsuit weight by adding compensatory weight in the form of air in your BCD or extra weight slabs on your weight belt but it’s nothing too difficult to manage.
If you’re wearing a rashguard or lycra skinsuit as mentioned above, the change in your overall weight will be negligible.
Any Specific Medical Considerations to Worry About?
Diving without a wetsuit isn’t just about freedom – it comes with its own set of medical “chill” factors. Without that cozy neoprene layer, you’re exposing yourself to the whims of the water temperature. Yes, you can get hypothermia even in warm waters if you overstay your dive time limit.
If you start feeling cold, and shivery, or your lips turn bluer than a Smurf, it’s time to call it a day and end your dive before hypothermia decides to gatecrash your underwater adventure. Dehydration can add fuel to the onset of hypothermia so take no chances and pay extra emphasis on hydration before attempting a no-wetsuit dive.
Other than this, the usual list of health conditions apply which might disqualify you from scuba diving on medical grounds.
