Conditions & Currents

Conditions at Bay Cones are generally calm, characterized by usually mild currents. This makes the site highly accessible and suitable for most certified divers, including beginners, as it does not typically present significant challenges related to water movement. The relaxed current environment allows for comfortable navigation and extended observation times around the artificial cones. Visibility is at its best from July to October, reaching 20-30 meters. Water temperatures during this peak season are also favorable, staying between 21-24°C. Divers should be aware of cooler temperatures and reduced visibility outside of the peak summer and autumn months, especially from December to March when conditions can be rougher. Given the mild nature of the site, special entry or exit techniques like negative entries or reef hooks are typically not required, ensuring a straightforward and enjoyable dive experience.

Dive profile & how the dive runs

Dive profiles around Portugal are highly site-dependent due to the diverse underwater topography and current conditions. Typically, dives are conducted from a boat, often involving a descent onto a reef, volcanic rock formation, or wreck. Depending on current strength, dives might be drift dives, allowing the current to carry you along the features while maintaining neutral buoyancy. For static dives, the route might follow a specific contour of the reef or explore a wreck's interior, gradually ascending towards shallower depths. Turnaround points are often based on air consumption or no-decompression limits, with a slow, controlled ascent. Safety stops are mandatory at 5 meters for 3 minutes, usually conducted either mid-water or holding onto a static line deployed from the boat, especially in areas with current.

Underwater photography

Capturing the diverse underwater scenery in Portugal often requires adaptability. For wide-angle shots, a fisheye or wide-angle lens is ideal to encompass the dramatic volcanic landscapes, large schools of fish, or potential pelagic encounters. Visibility can sometimes exceed 30 meters, allowing for expansive reef or wreck photography. In shallower areas with good light, natural light can be sufficient, but strobes are recommended to bring out the vibrant colors of marine life and corals, especially at greater depths or in dimmer conditions like inside caves. For macro subjects such as nudibranchs, octopuses, and cuttlefish, a macro lens with powerful strobes or a snoot will be essential to highlight intricate details. Practicing excellent buoyancy control is crucial for getting close to subjects without disturbing them, particularly in areas with surge or current.

Getting there & logistics

International travelers typically arrive in Portugal via major airports such as Lisbon Portela Airport (LIS), which serves as a convenient hub for mainland dive sites like Sesimbra. For diving in the Algarve, Faro Airport (FAO) is the primary gateway, while Madeira is served by Funchal Airport. Trips often range from day excursions to multi-day liveaboard experiences, particularly for the Azores or remote offshore sites. Most diving is boat-accessed. There are no general marine park fees mentioned for the specific site 'Bay Cones' in the sources, but divers should inquire about any local permits or fees at their chosen dive center. It's common for dive trips to Portugal to combine diving with exploring the country's cultural attractions or other outdoor activities like hiking, especially in Madeira and the Azores.

Safety & environment

Diving in Portugal, particularly in areas with strong currents or deeper sites, necessitates adherence to strict safety protocols. Divers should always carry valid dive insurance covering emergency medical treatment and evacuation, as recompression chambers may not be immediately nearby, especially for remote island or offshore locations. Evacuation reality can involve boat transfers to shore and then road transport to medical facilities. Site-specific hazards include dynamic currents requiring proper drift diving techniques, potential for surge in shallow areas, and cold water temperatures in winter necessitating appropriate thermal protection. Divers should always follow their dive guide's instructions, maintain good buddy practices, and stay within their training limits. Carrying an SMB and a whistle is advisable, especially for drift dives or in open water.
