Dive Site Characteristics
Key Dive Site Facts
Dive Site Overview
Planning a dive at Selsey Beach often revolves around the tides, providing different experiences depending on conditions. Divers can opt for slack water, typically around HW-4 or HW+3, for a calmer exploration of the nearshore environment.
Alternatively, the site accommodates drift dives during flood or ebb tides, offering a dynamic perspective of the seabed as currents carry you along. Depths at the beach itself are quite shallow, reaching a maximum of 6 m (19 ft), which is suitable for entry-level certifications.
However, the wider Selsey area offers deeper dives, with some sites reaching up to 40 m (130 ft) to explore wrecks and reefs. This site is also a rewarding night dive location, revealing different nocturnal marine life behavior.
A surface marker buoy is consistently recommended given the active nature of the surrounding waters.
Best Time to Dive
Optimizing a dive at Selsey Beach involves balancing various climatic factors across the year. The best conditions are generally observed from May through June, when dive scores are consistently 'Good', and air temperatures are more agreeable, averaging around 13-17°C (55-63°F). Wave heights also tend to be lower during these months, facilitating easier shore entry and improved visibility. In contrast, winter months like January and December see lower dive scores and cooler air temperatures, typically 6-9°C (43-48°F), accompanied by higher average wave heights. Rain showers are less frequent in late spring and early summer, though conditions can still vary. Cuttlefish are a seasonal highlight, primarily encountered from May into late summer.

Dive Experience & Conditions
The dive experience at Selsey Beach is characterized by its accessible shore entry and relatively shallow profile, with a maximum depth of 6 m (19 ft) directly off the beach. While the immediate area is within recreational depth limits, the broader Selsey waters extend to 40 m (130 ft) for more advanced explorations. Conditions largely depend on the tidal state; slack water offers a more controlled dive, ideal for new divers or those focusing on macro life. Conversely, planning for a drift dive during active tides can introduce a different pace, suitable for divers comfortable with currents. The water type is saline, as expected in the English Channel. Visibility is variable and can be influenced by recent weather, tides, and local sediment disturbance. It's a versatile site, accommodating divers from PADI Open Water to those seeking advanced certifications like DSMB Diver or Dry Suit Diver.
Dive Difficulty & Safety Guidelines
Diving at Selsey Beach requires careful consideration of its active environment as a working fishing beach. Divers must remain vigilant for potential hazards such as ropes and wires on the beach, which can be slippery from grease or oil and may be actively moving due to winching operations. Boat traffic from the local fishing fleet and the Lifeboat is a continuous concern; therefore, the consistent use of a Surface Marker Buoy (SMB) is critical for diver visibility. Tidal planning is essential, as the site can be dived on slack water or as a drift dive on either flood or ebb tides. Understanding local tide times is paramount for a safe and enjoyable experience. Always check local conditions prior to entry.

Recommended Dive Suit
Subtle variations in currents or depth can sometimes influence perceived water temperature.
Drysuit (strongly recommended) tends to perform well in water temperatures like those currently observed here. A hood or vest is suggested for sensitive divers due to surface winds. Strong cold advisory: dress warmly immediately after exiting the water. Environmental models indicate a modest warming trend ahead. A warming trend is expected over the next few days.
