Pumpkin Carving Underwater and Why Drysuit Season Starts Now

October at Reading means two things arrive at once, and they could not be more different in tone. The first is genuinely daft and enormous fun, the Pumpkin Carving specialty dive that has become something of an autumn tradition among our club divers. The second is a lot more practical, the point in the year when UK water temperature drops enough that carrying on in a wetsuit stops being sensible for most divers. Handily, they land in the calendar at almost exactly the same time, so it is worth talking about both together.

What the Pumpkin Carving Dive Actually Involves

The premise is exactly what it sounds like. Divers bring a pumpkin, carving tools appropriate for use underwater, and a willingness to attempt fine motor skills through thick gloves in cold, often low visibility conditions, then carve a face into the pumpkin while fully submerged. It sounds like a novelty and it absolutely is one, but it also happens to be a genuinely useful skill builder disguised as a party trick.

Carving underwater demands careful buoyancy control, since drifting up or down mid-carve makes a mess of the design and risks losing tools into silt. It demands good trim, so you are not kicking up the bottom and ruining visibility for your buddy. And it demands the kind of task loading that instructors love to test, doing something fiddly with your hands while still monitoring depth, air, and your dive partner. Underneath the silliness, it is a legitimate skills session wearing a Halloween costume.

Getting Involved

Pumpkin Carving sessions typically run as a fun club evening or weekend event through the academy calendar, usually in a UK quarry or sheltered coastal site depending on conditions and who is available to run it. It suits any certified diver comfortable at the relevant depth, no special qualification is required beyond your existing certification, though a drysuit is strongly recommended by this point in October for reasons we are about to get into.

Why Drysuit Season Genuinely Begins in October

UK sea and quarry temperatures drop steadily through autumn, and by mid-October many popular training and club sites have cooled enough that a standard wetsuit, even a thick one, starts to struggle to keep divers comfortable for a full dive. Cold does more than make you miserable, it also degrades judgement, increases air consumption as your body works harder to stay warm, and shortens the dives you can comfortably enjoy. A drysuit, worn with the right undersuit layers, keeps you properly warm well into winter and genuinely extends the diving season rather than forcing a pause until spring.

The switch from wet to dry is not simply a different suit, it changes your buoyancy and trim characteristics noticeably, since you are now managing air in two separate spaces, your BCD and the suit itself. This is exactly why we run dedicated drysuit training rather than assuming divers can simply put one on and get in the water. Poor drysuit technique leads to feet-first ascents when air migrates to the legs, or overweighting that makes a dive exhausting rather than relaxing.

What Drysuit Training Actually Covers

A proper drysuit course covers correct weighting for the specific suit and undersuit combination, managing suit inflation and deflation independently from your BCD, controlling trim so air does not pool in your legs or shoulders unexpectedly, and practising the emergency procedures specific to suit flooding or valve failure. None of this is complicated once practised properly, but it is genuinely different enough from wetsuit diving that skipping proper instruction is a false economy, particularly for UK winter diving where the margin for error from cold and current is smaller.

Choosing Between Neoprene and Membrane Drysuits

Neoprene drysuits offer some inherent insulation from the suit material itself and tend to feel more forgiving to new drysuit divers, at the cost of being slightly bulkier and, over years of use, prone to compressing and losing some of that insulating quality at depth. Membrane drysuits rely entirely on the undersuit layers worn beneath for warmth, which means colder dives require thicker undersuits, but the suit itself tends to be lighter, easier to pack for travel, and simpler to repair. Neither is objectively correct, UK divers doing mostly local diving from Reading often find neoprene suits a comfortable, forgiving starting point, while divers planning to travel with their kit sometimes prefer the packable nature of membrane suits.

Getting Ready for the Season Ahead

If you are planning to keep diving through winter, now is genuinely the right moment to sort out drysuit training and kit, rather than waiting until November when water temperatures have dropped further and the transition feels more urgent and less enjoyable. Booking a fitting, working through proper training, and getting comfortable in a controlled environment before the coldest months arrive makes the whole winter diving season considerably more relaxed.

Kit Beyond the Suit Itself

Drysuit gloves or dry gloves are worth thinking about at the same time as the suit, since bare or thin wet gloves become genuinely uncomfortable once water temperature drops through October and November. Many divers underestimate how much cold hands affect an otherwise enjoyable dive, fumbling with clips and fasteners becomes noticeably harder once fingers stiffen up, which matters even more during a task-loaded session like pumpkin carving where fine motor control is the entire point. A well-fitted hood, ideally one that pairs properly with your mask skirt as discussed elsewhere on our blog, rounds out the cold water setup and prevents the surprisingly large heat loss that happens through an exposed head.

A dive computer that tracks your specific gas mix and depth profile properly also becomes more important as winter diving conditions add complexity, since cold water dives often run at more conservative profiles than warm water equivalents, and a computer that clearly displays your no-decompression limits helps you plan sensibly around shorter, colder dives rather than relying on memory or tables alone.

Making the Most of the Darker Months

It is worth reframing UK winter diving as its own distinct season with its own rewards rather than simply an endurance test until spring returns. Visibility at many UK sites genuinely improves once summer algae blooms die back, cold water often means fewer other divers and boats around popular sites, and there is a particular satisfaction to a well-executed cold water dive that summer diving rarely offers in quite the same way. Club events like the Pumpkin Carving dive exist partly to make sure the social side of the club calendar does not quietly fade out once the weather turns, keeping the community diving together right through winter rather than only reconvening again in spring.

Frequently Asked Questions

Do I need my own drysuit before starting the training course?

No, hire suits are available for training so you can build the skill and confidence before committing to a purchase, which is usually the sensible order to do things in anyway.

Is the Pumpkin Carving dive suitable for newly qualified divers?

Generally yes, provided the site and depth match your current certification level, it is a fun, low-pressure way to practise buoyancy and trim in a social setting rather than a formal training exercise.

How cold does UK water actually get in winter?

Depending on the site, water temperature can drop into the low single digits by midwinter, which is exactly why proper drysuit training and the right undersuit layering matter so much for comfort and safety.

Can I wear a drysuit for the Pumpkin Carving dive itself?

Absolutely, and by October most participants do. It also means the fine motor challenge of carving is even more realistic practice for winter diving conditions generally, since dry gloves change how tools feel in your hands compared with bare or wet gloved fingers.
