Sea Temperature in Croatia 2026: Best Time to Swim & Sail
Croatia sea temperatures month by month — when the Adriatic is warm enough to swim, when it’s perfect for catamaran charter, and how north differs from south.

Updated June 2026.
This is the 2026 operator’s guide to Croatian marinas — the densest marina network in the Mediterranean and the workhorse infrastructure of every charter week. The Croatian marinas 2026 guide covers ACI vs private vs town quays vs mooring buoy fields, the fees you will actually pay, which marinas need early booking, and which deliver the best week-of-charter experience.
Three main categories plus mooring buoys:
— ACI Club Marinas (22 locations) — the largest network, state-affiliated, standard pricing, full services
— Private marinas (D-Marin, Marina Frapa, Marina Lav, NCP, Marina Kremik, Marina Kornati) — often newer, similar pricing
— Town quays (Hvar, Vis, Stari Grad, Komiža, Bol, Brač) — cheaper, less reliable, walk-in basis
— Mooring buoy fields (Krka, Mljet, Telašćica, Lastovo, Vinogradišće) — cheap, common in protected areas.
22 ACI Marinas cover the Croatian Adriatic from Umag in the north to Dubrovnik in the south. Standard services at all locations: shore power 16-32A, water, fuel at major marinas, marina office, restrooms, security, restaurant. 2026 mid-week rate for a 47 ft catamaran in peak season: €125-180 per night; shoulder season: €85-130.
The ACI App reserves berths from 30 days ahead. Major peak-summer weekends fill 4-6 weeks ahead. ACI Card holders get 10% discount.
Key ACI Marinas:
— ACI Split: home base for many fleets
— ACI Trogir: alternate Split-area, less crowded
— ACI Palmižana (Pakleni): must-book 6-8 weeks ahead
— ACI Korčula: small, fills fast in August
— ACI Skradin: closest marina to Krka National Park
— ACI Dubrovnik (Komolac): south Croatia base, higher pricing.

— Marina Frapa (Rogoznica): newer than most ACI, full services, mid-route
— Marina Lav (Split, Podstrana): newer, upscale, near Le Méridien Lav
— D-Marin Mandalina (Šibenik): major Šibenik base, newer infrastructure
— NCP Marina Mandalina (Šibenik): charter-focused, same complex
— Marina Kremik (Primošten): mid-route option
— Marina Kornati (Biograd): Zadar region.
Private marinas typically price within €10-20 of ACI for the same boat. The decision is usually based on route geography rather than price.

Many island towns offer the “riva” (town quay) as an alternative to a formal marina. Mooring fee runs €65-120 per night for a 47 ft catamaran, roughly half the marina rate.
— Hvar town quay: fills by 14:00 in peak
— Vis town quay: smaller, similar peak-season rush
— Stari Grad town quay: less competitive, often the better Hvar-island choice
— Komiža town quay: small but workable in shoulder
— Pakleni Vinogradišće: combined town quay + mooring buoy
— Bol on Brač: limited berths, book ahead.
The town-quay approach: arrive by 13:00 in peak, find a free spot, communicate with the harbour master, pay cash to the rep who walks the quay.

— Krka National Park entrance: required mooring buoys near Skradin
— Mljet Polače and Pomena: mooring fields inside the national park
— Telašćica (Dugi Otok): nature park mooring field
— Lastovo Skrivena Luka: nature park mooring
— Pakleni Vinogradišće: combined buoys + restaurant tender service.
2026 mooring buoy fees run €25-50 per night for a 47 ft cat. Park entry fees are separate.

Realistic 7-day budget for a 47 ft catamaran, peak, middle Dalmatia route:
— ACI Marina nights (3) × €150 = €450
— Town quay nights (2) × €90 = €180
— Mooring buoy nights (2) × €40 = €80
— Total marina/mooring: €710 across the week.
For a middle Dalmatia week, the early-booking priorities:
1. ACI Palmižana — 6-8 weeks ahead in peak
2. ACI Korčula — 4-6 weeks ahead
3. Hvar town quay — no booking, arrive by 13:00
4. ACI Skradin — 4-6 weeks ahead if Krka is on the route
5. Vis town quay — arrive early, low-reliability.
Almost every Croatian marina provides shore power and water. Standard 16A or 32A, 230V single-phase. Confirm at booking that your boat’s amperage matches. Water is metered at some private marinas, included at most ACI berths. Pump-out (black water) at ACI Split, Trogir, Šibenik, and most private marinas; charter operators handle this at end-of-charter.

Yes for a 7-day charter with 3+ ACI overnights. The €50 card pays back at 3-4 nights via the 10% discount.
Yes at all ACI Marinas and major private marinas. Town quays and mooring-buoy fees are usually cash-only.
ACI Marinas at major locations have 24/7 reception. Smaller marinas close at 22:00; berthing is possible, payment is settled in the morning.
Med-mooring (stern-to). Bow anchor out, stern lines to the quay. The harbour master walks the quay collecting fees in the late afternoon; pay in cash with a receipt.
Yes. Some ACI berths cannot accept catamarans wider than 8 metres. The major performance cats (9-10 m beam) need outside berths or anchorage instead. Confirm at booking with the marina.
Plan the route with the Split to Dubrovnik itinerary or Zadar Kornati route.
