How deep is the sea in Egypt and how does it change with tides?

Tide times are not fixed: there are usually two high and two low tides per day, with their timing shifting by roughly 40–60 minutes daily. Low tides can be stronger around the full moon, so checking a current tide table in advance is useful.

The lagoon can remain deep enough for swimming even at low tide. However, debris may sometimes wash ashore after about 3 pm; the lagoon is generally cleaner before then.

Depth varies greatly by spot: at high tide, water by the pontoon can reach chest level, and the bottom may not be reachable near the buoys. At low tide, the pontoon area is often still waist-deep, while shore water is usually below knee level and the seabed can be exposed during an especially strong low tide.

Tides alternate every 6 hours — peak depth typically around 6am and 6pm. The water level difference between high and low tide is approximately 40 cm.

During low tide mornings the water was very shallow, while afternoon high tide reached waist-deep. On average, the sea was knee-deep for most of the day.

Over a 10-day stay, morning depth ranged from ankle to mid-thigh depending on the tide phase that day — conditions varied noticeably from day to day.
