Your Early Summer Diving Checklist, Plus World Turtle Day

Late May sits right at the point where the UK diving season properly wakes up. Sea temperatures are climbing, the evenings are light enough for an after-work shore dive, and holiday season is close enough that trip planning has moved from vague daydream to actual bookings. It also happens to include World Turtle Day on the 23rd, a useful annual reminder that the ocean we dive in every weekend is worth looking after. This post pulls both threads together, a practical early summer checklist for divers, with a nod to why marking days like World Turtle Day genuinely matters for anyone who spends time underwater.

Service and Check Your Kit Before the Season Ramps Up

Equipment that has sat in a cupboard since last autumn deserves a proper check before it goes back in the water, especially anything life-support related. Regulators should be serviced annually regardless of how much they were used, since internal components degrade with time as well as use, and a winter of storage is not a reason to skip a service that was already due. BCDs benefit from an inflator check and a look over the dump valves, and cylinders need a current test date if you are hiring or filling through a dive centre.

This is also the point in the year to check smaller items that get forgotten, torch batteries, mask straps that have gone brittle, fin straps, and the condition of any exposure protection you have not worn since last summer. None of this takes long individually, but leaving it all until the morning of your first dive of the season is how small problems turn into a wasted dive day.

Rebuild Skills You Have Not Used Over Winter

Even divers who train year-round tend to dive less through the darker, colder months, and skills that felt automatic in September can feel a little rusty by May. Buoyancy control, mask clearing under stress, and basic navigation are all worth a confidence check on an early, easy dive before you commit to anything more demanding. If you have booked an ambitious summer holiday, a local UK dive gives you a much lower-stakes place to notice and fix any rust than a reef wall on day one of a trip abroad.

If it has been a while, or if you simply want to sharpen specific skills before summer, our instructors run regular sessions covering exactly this kind of skills refresh across our course pathways, whether that means a short confidence-building session or working toward the next certification level entirely.

Sort Your Summer Trip Logistics Early

Popular dive destinations and liveaboards fill up well ahead of peak season, and May is genuinely the point where waiting any longer starts to limit your options for the summer months. If a holiday is on your list this year, it is worth deciding roughly when you want to travel and starting to look seriously rather than leaving it until July and finding the trip you wanted is fully booked. Our holidays page and expedition trips page are both worth a browse for inspiration, and our international team can talk through timing against things like weather windows, water temperature, and wildlife seasons for specific destinations.

Insurance and paperwork are worth sorting at the same time as the excitement of booking, not the week before you fly. Check your dive insurance covers the depths and activities you actually plan to do, confirm your certification card is current and easy to access, and make sure any medical declarations required by your destination are dealt with well in advance rather than as a last-minute scramble at check-in.

What to Pack for an Early Season UK Dive

Early summer in the UK can still be genuinely cold underwater, even on a warm, sunny surface day, so it is worth packing as though conditions will be more demanding than the weather forecast suggests. A proper hood, gloves, and boots matched to your suit are not optional extras at this time of year, and a spare set of thermal layers under a drysuit undersuit is worth having in the car even if you do not expect to need them. Surface conditions can also change quickly on UK coasts, so a warm layer for between dives, a flask of something hot, and a windproof jacket for the boat or shore make a bigger difference to how enjoyable the day feels than most divers expect.

It is also worth double-checking safety equipment specifically at the start of the season rather than assuming everything is exactly as you left it last year. A working SMB and reel, a cutting tool, and a properly charged torch if you are diving anywhere with reduced visibility are all worth a quick inspection, since these are the items most likely to have been forgotten in a kit bag over winter and most likely to matter if something does not go to plan.

World Turtle Day and Why Small Awareness Days Matter

It would be easy to dismiss something like World Turtle Day as a minor date on the calendar, but days like this genuinely do drive real conservation attention and funding toward species that need it. Sea turtles face a long list of pressures, from plastic pollution to nesting beach disruption, and a coordinated day of global attention helps conservation organisations reach people who might not otherwise think about the issue at all. For divers specifically, it is a useful annual nudge to think about how our own habits, from sunscreen choice to how we behave around wildlife underwater, affect the animals we travel to see.

If turtles or wider marine conservation genuinely interest you, our Conservation Academy goes well beyond a single awareness day, covering species identification, survey work, and habitat protection for divers who want to turn an interest into a proper skill set. It sits alongside our other five academies, Scuba, Professional, Tec, Freediving, and Mermaid, as one of six structured pathways through our training programme.

A Simple Early Summer Checklist

Pulling all of this together, a sensible early summer routine looks something like this: get your regulator serviced if it is due, check smaller kit items you have not touched since last year, book a confidence dive or skills refresh if you have not been in the water for a while, decide on your summer holiday plans and start looking seriously rather than waiting, and confirm your insurance and paperwork are current well ahead of any travel. None of these steps takes long on its own, but doing them in May rather than discovering a gap in June saves a huge amount of stress once the season is properly underway.

Frequently Asked Questions

How often should dive equipment be serviced?

Regulators should generally be serviced annually regardless of use, while BCDs and other equipment should be checked at least once a season and serviced according to manufacturer guidance.

What is the best way to shake off rust after a winter break?

An easy, low-stress local dive or a short skills refresh session is the best way to rebuild confidence before committing to a demanding dive or a big holiday.

How far ahead should I book a summer dive holiday?

As early as you reasonably can, since popular destinations and liveaboards fill their peak season slots well ahead of time.
