Browse All GuidesA snorkel is simple kit, but a bad one makes surface swims miserable. In UK conditions: choppier seas, regular wave wash, and entries that often involve swimming across the surface to the dive site. The difference between a decent dry-top snorkel and a cheap semi-dry is real and felt on every dive.

Dry vs Semi-Dry: What Matters in UK Waters
Semi-dry snorkel: Has a splash guard at the top that deflects direct wave splash but does not seal. Water can still wash in if a wave catches it from the side. Simple, reliable, affordable.
Dry top snorkel: Has a valve at the top that seals completely when submerged. Water cannot enter the tube at all. When you surface, the valve opens automatically and you can breathe immediately.
In calm, warm water, a semi-dry snorkel is fine. In UK coastal conditions, where surface swells regularly push waves over your snorkel and entries at rocky sites involve getting your face wet before you are ready, a dry top makes the surface swim notably more comfortable. The difference is not subtle when you are fighting a surface swell at a site like Swanage or Torbay.
Most UK dive instructors recommend a dry top snorkel for new divers. The extra £10-12 over a semi-dry is worth paying at any UK shore dive site.
There is a third category worth mentioning: snorkels with a flexible, foldable lower section (like the Aqualung Impulse 3) that tuck into a BCD pocket easily. These are popular with UK divers who carry a snorkel occasionally rather than every dive.
Cressi Supernova Dry: Best Overall (Around £30)
The Cressi Supernova Dry is what most UK dive shops and instructors recommend. Italian-made, widely trusted, and the dry top valve genuinely works across real UK conditions.
The purge valve at the base of the tube makes clearing straightforward. A gentle exhale pushes any residual water out through the one-way valve at the bottom. You do not need to blast-clear the Supernova; the purge handles it with minimal effort. The flexible corrugated lower section reduces jaw fatigue during long surface swims and makes the mouthpiece angle comfortable even with a full-face mask seal in place.
The Supernova appears repeatedly on PADI and BSAC recommended kit lists because it does the job without fuss. It is not the lightest or most compact snorkel available. It is heavier than basic semi-dry options and slightly bulkier to pack. The dry valve mechanism also adds a marginal amount of breathing resistance compared to an open tube, noticeable on very long surface swims but irrelevant in normal use.
This is the main downside of dry top snorkels generally: the valve adds minimal resistance. For most divers and most conditions this is undetectable. For freediving or very long surface swims, some people find it noticeable. If you plan to do significant freediving, a simpler snorkel is better.
Pros: Dry top valve, purge valve, flexible tube, Italian manufacturing, widely available from UK dive shops Cons: Dry valve adds a small amount of resistance; bulkier than semi-dry designs; slightly heavier
Mares Ergo Dry: Best Ergonomic Option (Around £25)
The Mares Ergo Dry has a dry top valve and a shaped mouthpiece that angles slightly downward. This ergonomic design reduces jaw tension compared to straight-tube snorkels, which is noticeable on longer surface swims.
The dry top valve seals reliably and the corrugated lower section is flexible and comfortable. At around £25, it undercuts the Supernova Dry slightly. For divers who have experienced jaw fatigue with a standard snorkel, the Ergo Dry's angled mouthpiece is worth trying in a dive shop before committing. Mouthpiece comfort is partly personal preference.
Pros: Dry top valve, ergonomic angled mouthpiece, comfortable for extended use, slightly cheaper than Supernova Cons: The ergonomic angle that some divers find comfortable others find awkward; try before you buy if possible
Aqualung Impulse 3: Best for Travel (Around £32)
The Aqualung Impulse 3 has a tri-fold flexible lower tube that collapses to fit in a BCD pocket or a small bag pocket. This is its main practical advantage over the Supernova Dry.
The dry top valve works reliably. The mouthpiece is comfortable for typical dive use. The fold-flat design is genuinely useful if you carry a snorkel on some dives but not all, or if you travel frequently and want to pack it inside a mask case. At around £32 it is slightly more than the Supernova but the packaging benefit justifies the price for divers who travel or value compact kit.
Pros: Folds compact for travel and BCD pocket storage, dry top valve, comfortable mouthpiece Cons: Marginally more expensive than Supernova, fold mechanism adds a potential failure point over time
Cressi Corsica: Best Budget (Around £20)
The Cressi Corsica is the semi-dry option in this range. No dry valve, just a splash guard at the top that deflects direct spray, and the flexible lower tube is comfortable for extended use.
For sheltered diving and pool use, it is perfectly adequate. For UK shore diving at exposed sites in any kind of swell, you will be clearing it more frequently than you would like. The honest limitation is that a splash guard does not prevent water entry from lateral wave action. At rocky UK shore dive sites with any surface movement, a semi-dry snorkel becomes an inconvenience.
The Corsica is a solid choice for pool training where surface conditions are irrelevant, as a backup snorkel, or as a first snorkel for someone who is not yet sure how much shore diving they will do. It is not the right choice as your only snorkel if you plan to dive UK coastal sites regularly.
Pros: Affordable, lightweight, splash guard, flexible corrugated tube, good for pool sessions Cons: Not fully dry: wave action in UK seas will push water in; wrong choice for regular shore diving
Do Scuba Divers Actually Use Snorkels?
More than beginners expect. At UK shore dive sites with long surface swims, a snorkel lets you breathe face-down without using tank air. On boats, you will sometimes surface well away from the entry point. At sites like Wembury, Kimmeridge, and the Farne Islands, surface swims of 200-400 metres to the dive site are routine, and a snorkel makes that swim substantially easier.
Many experienced UK divers stop carrying a snorkel routinely once they are comfortable with their gas management and dive sites. It is standard kit for PADI Open Water and BSAC Ocean Diver courses, and useful to have even if you do not use it on every dive.
Where snorkels are most useful in UK diving: - Shore entries with surface swims longer than 100 metres to the dive site - Boat diving where you surface some distance from the vessel - Emergency use: if you run low on gas near the surface, ascend, remove the regulator, and snorkel to the exit point - Any dive site with significant surface movement where breathing conserves tank air
Snorkel Fit and Mask Compatibility
A snorkel clips to the mask strap with a snorkel keeper, a rubber ring or clip that holds the snorkel barrel against the strap. All snorkels in this guide use standard-size barrels that are compatible with standard snorkel keepers. If you buy a mask and snorkel separately, check that the keeper fits the barrel diameter of your chosen snorkel. Cressi, Mares, and Aqualung all use compatible standard sizes.
The snorkel should sit comfortably on the left side of your mask. The mouthpiece should rest naturally in your mouth without pulling the mask strap forward. Try the combination in the pool before taking it to a sea dive to check the fit and mouthpiece angle are comfortable for your face.
Snorkel Maintenance
Snorkels are low maintenance, but they degrade over time. Rinse in fresh water after every salt water dive. Salt crystallises in the mouthpiece and tube and degrades silicone over time. Store away from direct sunlight. UV light degrades silicone and plastic over months and years. Replace the mouthpiece if it develops tears or hardens significantly. Mouthpieces are usually available separately and cheaper than replacing the whole snorkel.
The average snorkel lasts 3-5 years with basic care. Dry top valves can occasionally stick after prolonged storage. Test the valve by submerging the snorkel briefly before relying on it after storage.
Which Snorkel Type is Right for You
If you are unsure which snorkel to buy, the answer depends almost entirely on where and how you dive:
Buy a dry top snorkel if: - You dive UK shore sites with any surface movement (this is most UK sites most of the time) - You do PADI or BSAC courses (dry tops are standard kit list items) - You want to avoid clearing the snorkel on every surface swim - You dive year-round in UK coastal waters
Buy a semi-dry snorkel if: - You primarily dive from a pool or indoor pool training sessions - You dive calm, sheltered inland sites (flooded quarries, calm reservoirs) - You need a backup snorkel and cost is the priority - You are a confirmed freediver who needs minimal flow restriction
The price difference between a decent semi-dry like the Cressi Corsica at £20 and a reliable dry top like the Supernova at £30 is a single tank hire at your local dive centre. The dry top is the sensible choice for almost every UK diver.
Snorkel Tube Length and Bore Diameter
Most recreational snorkels fall within a standard tube length of 38-42 cm and bore diameter of 2-2.5 cm. These dimensions represent a reasonable balance between purging ease and breathing resistance. Shorter tubes reduce the chance of swamping but slightly increase re-breathing of exhaled air in very humid conditions. Wider bore diameters make breathing marginally easier but make the snorkel bulkier and heavier.
None of the snorkels in this guide require active concern about these specs. They are within standard recreational ranges. If you are buying a freediving snorkel, tube length becomes more significant because blast-clearing technique relies on short, sharp exhalations. For recreational scuba, standard dimensions are fine.
UK Dive Site Surface Conditions
Understanding what conditions your snorkel will face helps explain why dry top matters. A few representative examples:
Swanage Pier, Dorset: Popular UK shore site with concrete steps entry. Surface swell is common in anything above Force 2. A short surface swim through boat wash and swell is standard before and after the dive.
Wembury, Devon: Rocky entry. Surface swim of 150-300 metres to the main reef. The swim is sheltered from wind swell but not from long-period Atlantic swell on exposed days. A semi-dry snorkel here means regular clearing.
Farne Islands, Northumberland: Boat diving with current. Entry and exit often involves swimming on the surface in moving water. A dry top lets you focus on the current, not on the snorkel.
Capernwray, Lancashire: Inland quarry with flat water. A semi-dry or any snorkel works fine here. The calm conditions mean surface movement is minimal.
The pattern is clear: coastal UK sites benefit from a dry top. Inland or sheltered sites are more forgiving.
Freediving and Snorkelling Considerations
Freedivers typically prefer a simple J-tube snorkel with no dry valve or purge valve. The dry top mechanism adds resistance when blast-clearing and can interfere with freediving technique. A low-volume, simple J-tube without extra mechanisms is the standard freediving snorkel. If you are primarily freediving rather than scuba diving, the Cressi Corsica or a dedicated freediving snorkel is more appropriate than the Supernova Dry.
For snorkellers (surface swimming, no diving), any snorkel in this guide works well. A dry top is most comfortable for surface snorkelling in any conditions with surface movement.
What to Avoid
Avoid cheap unbranded snorkels from general sports retailers. The dry top valves on budget unbranded snorkels often fail quickly, and the mouthpiece silicone is rarely comfortable for extended use. The price difference between an unbranded snorkel and a Cressi Supernova is around £10-15. It is not worth saving that on dive kit.
Avoid semi-dry snorkels as your primary snorkel for UK shore diving. If you regularly dive exposed UK sites with surface movement, a semi-dry snorkel means frequent clearing. A dry top snorkel is worth the small extra cost.
Avoid buying a snorkel online without checking mouthpiece compatibility with your mask. Most combinations work, but it takes ten seconds to check. A snorkel mouthpiece that pulls your mask forward or requires constant jaw tension to hold is a genuine dive safety distraction.
Avoid full-face snorkel masks for scuba diving. Full-face masks for snorkelling are not compatible with scuba regulator use and are not suitable as dive masks. They are for surface snorkelling only.
Frequently Asked Questions
Is a dry top snorkel worth the extra cost? For UK diving, yes. The extra £10-15 over a semi-dry is consistently worth paying if you dive any coastal site with surface movement. The dry valve removes the need to clear your snorkel on every surface swim, which is a real benefit when you are managing kit, watching for boats, and swimming against a surface current.
Can we use the same snorkel for scuba diving and snorkelling? Yes. The snorkels in this guide are suitable for both. For scuba diving, you attach the snorkel to your mask strap and use it for surface swims. You remove it before descending and it clips tidily out of the way. For surface snorkelling, you use it continuously. A dry top works well in both roles.
Do I need a snorkel for every scuba dive? Not every dive, but most UK divers carry one for shore diving. The mandatory kit list for PADI Open Water and BSAC Ocean Diver includes a snorkel. Once you are certified, whether you carry one is personal preference. At sites with long surface swims or unpredictable conditions, having a snorkel is the sensible choice.
What is the difference between a dry top and a semi-dry snorkel? A dry top has a mechanical valve at the top of the tube that seals completely when the snorkel is submerged or swamped by a wave. Water cannot enter. A semi-dry has a splash guard that deflects direct splash but does not seal. Water from lateral wave action or full submersion can enter a semi-dry tube. In calm conditions the difference is minor. In UK coastal conditions with surface swell, it is significant.
Our Recommendation
For most UK divers, the Cressi Supernova Dry at around £30 is the right choice. Dry top valve, purge valve, flexible corrugated tube, and the most widely recommended snorkel at UK dive clubs and shops.
If you travel frequently or want compact storage, the Aqualung Impulse 3 at around £32 adds fold-flat convenience for a couple of extra pounds.
If jaw comfort from a straight tube is an issue, try the Mares Ergo Dry at around £25 with its angled mouthpiece.
For pool training, the Cressi Corsica at around £20 is adequate and inexpensive.
For the rest of your dive kit, see the dive masks guide, fins guide, and the beginner gear checklist for the full starting kit picture.
A good snorkel costs £25-30, lasts several years, and removes a real inconvenience from UK shore diving. Buy the Supernova Dry, clip it to your mask, and stop thinking about snorkels.
