Diving Mellieha: arches, wrecks and northern shore diving

Mellieha works best as a land-based base for exploring northern Malta underwater. A diver can begin with a shore dive in Mellieha Bay, then use short boat trips to reach Comino, Cirkewwa and sites such as Double Arch or the P31 wreck. The setting is practical rather than resort-isolated: diving is combined with beaches, coastal walks and village life. Four to seven days gives enough time to mix formats, repeat a favourite site and leave room for a change of sea conditions.

The diving is built around rock rather than one continuous reef. Arches, caves, walls and broken coastal relief provide the main underwater structure, with small wrecks and artificial features adding variety. Double Arch is the more demanding proposition: its recreational profile reaches 38 metres, while deeper sections extend towards 80 metres for technical divers. By contrast, P31 lies at about 18 metres and has passages that make the patrol boat more than a simple swim-around. Current is variable, so the same site may feel straightforward on one day and less comfortable on another. Shore dives and short boat outings sit naturally alongside each other. Visibility is not presented as a fixed local constant, although P31 is often described with more than 20 metres of clear water and generally little current.

Marine life is woven into the rocky scenery rather than presented as a separate wildlife show. At Double Arch, the twin formations provide shelter and surfaces used by local marine life, giving the diver something to examine while moving through the arches and around the rock. On P31, attention turns to the wreck’s structure: passages, openings and the outline of the former patrol boat create the places where life can be observed at close range. Protected areas around Comino, Għadira and Il-Majjistral reinforce the need to leave that setting undisturbed. The most dependable seasonal advantage is practical: calmer water from May to October makes it easier to spend time looking closely at rock and wreck rather than simply managing movement.

May to October is the measured window for the calmest sea, while June to October brings the lowest rainfall. April, May, June, September, October and November are sensible months for a diving stay when a balance between workable conditions and a quieter feel matters. The northern sites and Comino become busier during holiday periods, particularly when calm weather encourages boat trips. Shore diving around Mellieha can offer a less crowded alternative. A stay in the shoulder months also makes sense for divers who want to spread their options across Mellieha Bay, Comino and Cirkewwa rather than depend on one boat day.

Mellieha suits all levels, provided the site is matched honestly to experience. Beginners can use suitable shore and boat sites, while experienced divers have more demanding relief to explore. Double Arch calls for deep-diving experience and careful buoyancy control; Advanced Open Water is useful preparation, and technical depth lies beyond ordinary recreational limits. PADI, SSI and BSAC divers should find the level discussion familiar, but certification alone does not replace comfort around rock, arches and changing depth. Nitrox is useful for repeated moderate-depth dives.

From London Heathrow, London Gatwick or Manchester, the journey begins with a flight to Malta, followed by a road transfer north to Mellieha. There is no compulsory sea crossing to reach the town itself. The important logistical decision comes afterwards: some dives start from the coast, while others require a local boat, particularly for Comino and sites around Cirkewwa. Accommodation in or around Mellieha can therefore be linked to dive centres on foot, by taxi or through a local transfer, depending on the chosen departure point. It is worth settling the shore-versus-boat plan before booking individual days, because the transport pattern changes from site to site. Boat schedules also determine how easily Comino and the busier northern locations fit into the week.

Treat Mellieha as a base for moving between micro-areas, not as a single-site holiday. Pair a Mellieha Bay shore dive with a boat day towards Comino or Cirkewwa, then keep a spare day for repeating the best option when the sea is calmer. Check the access for every booking: a shore entry demands a different plan from a short boat departure, and assuming everything is boat-based wastes the flexibility that makes the area useful. For Double Arch, judge the dive by depth and buoyancy rather than by the general claim that northern Malta suits all levels. P31 is the easier wreck day, with its 18-metre resting depth, passages and usually limited current. Early departures make sense for the best-known northern sites, before boat rotations bring more groups together. Nitrox can be worthwhile when several moderate-depth dives are planned. Do not expect one grand reef; the appeal lies in linking rocky, wreck and cave-like scenery.

A four- to seven-day stay works well from Mellieha. Use the first days for nearby shore diving and local orientation, then add boat trips towards Comino and Cirkewwa. Keep the schedule loose enough to repeat a site when conditions suit it, rather than filling every day with a fixed departure. Non-divers have beaches, coastal viewpoints, walks, Comino excursions and northern Maltese heritage close at hand, so the trip does not need to revolve entirely around diving.

Your last day stays dry: no diving in the 18-24 hours before a flight the perfect window to see the destination from another angle.
