How deep is the water from shore to the buoy line at Egyptian beaches?

One guest gave a detailed description of the hotel's long beach, divided into 4 zones: sunbed area, a small lagoon (forms at low tide, resembling a small lake), the main beach, and another lagoon at the far end. In that lagoon, you reach deep water fairly quickly but by wading in on foot. Separately, there is a pier/pontoon built directly over deep water — descending its stairs takes you straight into deep water where the reef begins, allowing immediate swimming along the reef.

The newest query asks about the maximum depth when entering from the shore, specifically for beaches without a pier. No exact depth figures were provided in the discussion.

One traveler specifically asked about the depth at the buoy line, meaning the practical concern is the actual swimming depth rather than a general beach description. No meter-based answer appears in the messages.

Another traveler asked whether the water stays only knee-deep when entering from the shore, showing that the key issue is whether the beach has a shallow entry or reaches swimmable depth quickly. The chat did not include exact measurements or photos.
