• Boat and ferry traffic: In summer, assume frequent boats near coves and MPAs. Use an SMB on ascent and tow a float when snorkeling or freediving.
• Wind and sea state: Strong regional winds can create rough surface conditions quickly. If winds climb toward 30.0 kph or more, switch to leeward sites or cancel boat crossings.
• Currents and surge: Headlands, channels, and walls can produce current lines and surge. Plan conservative exits and keep gas reserves.
• Thermoclines: Expect colder water at depth, even in summer. Plan exposure protection for the coldest part of the dive, not the surface.
• Overhead environments: Caves require redundant lights, training, and conservative navigation. Do not exceed your certification.

Italy has a well-developed medical system and established hyperbaric medicine capability in many coastal regions. For diving-related issues, a conservative approach is best: stop diving, call emergency services, and contact a diving medical hotline.

• Use 112 for general emergencies.
• Use 1530 for maritime emergencies (Italian Coast Guard).
• 118 may still connect you to medical emergency response in many areas.
• Consider membership with DAN Europe and keep the hotline details accessible on your phone and dive kit.

Italy's marine conservation is heavily shaped by MPAs and seagrass protection.

• Respect zone boundaries and any requirements for authorized guides.
• Never anchor on Posidonia seagrass meadows. Use mooring buoys when provided.
• Do not touch, collect, or remove marine life, shells, or artifacts.
• Use reef-safe sunscreen and keep fins and hands off the bottom in shallow coves.
• Give wildlife space and avoid flash photography on sensitive subjects.
