The sea temperature at Cefalù peaks at 26°C in August and stays above 20°C through October. The water is clean and clear from June onward, and what is underneath it at Kalura is genuinely unusual: a protected archaeological zone with Roman port structures, amphora fragments, and a 16th-century cannon on the seabed — visible to snorkellers in shallow water and accessible to divers across seven sites.
This guide covers what we use and what guests consistently rate well: snorkelling spots, the two diving centres, SUP rental, kayaking, boat tours for a half-day on the water, and the fishing trips that are unlike anything you will find on the main beach strip. Water sports season runs roughly June to October, with the warmest, calmest conditions in July and August. Early morning is best for flat water on any given day. If you want to combine a morning in the water with a hike or a ride the same day, see our active day itinerary for how we sequence it.
Snorkelling — where to go and what you will see
Kalura Beach (Spiaggia Caldura) is the best snorkelling spot accessible on foot from Cefalù. Twenty minutes east along the coast road, past the marina, the cove sits below a 16th-century watchtower. The water is deep and very clear from the shoreline. The seabed here is a protected archaeological zone — former Roman port — and with decent visibility and a mask you can see stone structures and amphora fragments even in the shallows. Bring your own gear; the beach club at Kalura rents loungers but not snorkel kits. Crowds are thinner than the main beach, even in July and August.
Settefrati, a quieter cove a few minutes from the old town, has dramatic rock formations and clear water. It is a better spot for observing fish life than Kalura — less archaeological, more ecological. Worth the short walk.
Mazzaforno, a rocky cove between Cefalù and Kalura, appears on most boat tour itineraries as a swimming stop. If you are not on a boat, it is reachable by road. The water is clear and the cove is sheltered.
Diving — Kalura Diving Center and H2OME
Kalura Diving Center at Hotel Kalura (Via Vincenzo Cavallaro 13) is a PADI Dive Resort with seven sites within five to twenty-five minutes by RIB. The Roman Port site is the one to request: protected archaeological zone, stone structures, amphora fragments, and a cannon from the 1500s — accessible to all levels. The wall dive goes to 50 m (typically dived at 16–25 m) with rich marine life including Mediterranean barracuda, octopus, moray eels, and seahorses. A Discover Scuba introduction runs around €120, and full Open Water certification around €480 over three to four days. Contact: diving@hotelkalura.com, WhatsApp +39 331 490 7788.
H2OME Diving & Snorkelling operates from Marina Yachting Cefalù at Porto di Presidiana (h2omediving@gmail.com). PADI, ISDA, and CMAS standards, courses from age six, and two-hour snorkelling trips by boat for non-divers. They are highly rated and a solid choice if Kalura is fully booked — expect broadly similar pricing to Kalura for equivalent courses, but confirm directly since they do not publish a fixed rate card.
SUP and kayaking
Piranha SUP School on the Lungomare Giardina rents boards from around €10 per hour and runs private lessons, guided snorkelling sessions, and surfing lessons. They also run summer camps for children. Eclipse Cefalù (Molo 19, northern lungomare — Instagram @eclipsecefalu) offers electric SUP rental and innovative pedal-powered boards for anyone who finds a paddle too much work — pricing is not published, so message them directly on Instagram or WhatsApp to confirm. Both operators are on the lungomare and easy to find.
Kayaks are rented informally from the main beach area. Tandem kayaks run around €16 per hour; three-person kayaks around €20 per hour. The best kayaking routes go east along the sheer cliffs toward Kalura, passing sea caves and inlets that are inaccessible on foot. Go early: by late morning in summer, thermal winds build and the swell picks up on an open coast.
Boat tours — half a day on the water
La Nina Cefalù (Captain Mario, Porto Turistico Presidiana) runs coastal tours twice daily at 10:00 and 15:00, three hours each, with swimming stops at Mazzaforno and Caldura. Snorkel masks are provided. Sunset tours also available. From €15 per person — good value and consistently well-reviewed for solo travellers and small groups.
Sea Land Tours covers similar coastal routes with an aperitif included, from €20 per person, with private sunset trips from €150. For those who want a full fishing experience rather than a scenic cruise, Pescaturismo Melissa (cefalupescaturismomelissa.com) runs six-hour fishing tours with lunch on board — the crew cooks the morning catch, bruschetta, a primo, and drinks are included. Around €94 per person, maximum ten passengers. The sunset cruise version (aperitif, fresh catch, ~€99) is the one most guests choose.
If you want to take the boat out yourself, Marina Yachting Cefalù (Via Presidiana 1) rents self-drive boats for €120 to €160 for four to eight hours, up to seven people — no skipper licence required for the smaller craft. Jet skis available from the same operator from €60 for thirty minutes.
When to get in the water
The sea reaches 22°C by June — comfortable for swimming without a wetsuit. July and August peak at 25 to 26°C; September holds at around 25°C. October sits at 22°C and many guests find it the sweetest month: fewer people, still warm water, calmer mornings. Snorkelling and diving visibility is best in summer when the water is stable. The strongest currents and highest waves are October to March, when the tramontana blows from the north.
For SUP and kayaking, early morning is reliable all season — the Tyrrhenian is typically flat before 10:00. By early afternoon in summer, thermal winds build along the coast and conditions change quickly. If you are paddling past the headland or east toward Kalura, check the wind forecast before you leave.
Common questions
Is the snorkelling good in Cefalù?
Yes, particularly at Kalura cove (20 minutes east of the old town). The seabed is a protected Roman archaeological zone with amphora fragments and stone port structures visible in shallow water. Settefrati is better for fish life. Bring your own gear — rental options are limited on the beach.
Where can I go diving in Cefalù?
Kalura Diving Center at Hotel Kalura is the main PADI operation, with seven sites including the Roman Port archaeological zone. H2OME at Porto di Presidiana is the alternative, with courses from age six. Both are well-regarded. Book ahead in July and August — spaces fill quickly.
What is the sea temperature in Cefalù?
May is around 18°C — cold for sustained swimming. June reaches 22°C, comfortable for most. July and August peak at 25–26°C. September holds at 25°C. October drops to 22°C. With a wetsuit the season extends comfortably through November at around 19°C.
Can I rent a boat in Cefalù without a licence?
Yes. Marina Yachting Cefalù rents self-drive boats for €120–160 for four to eight hours with up to seven people aboard. No skipper licence is required for the smaller craft. Alternatively, several operators run half-day coastal tours from €15 per person, including swimming stops and snorkel gear.
