What the community said
In December the sea water in Marsa Alam is cold — swimming without a wetsuit (winter version) is uncomfortable; some prefer the hotel's heated pools instead of the sea.

A wetsuit is a must in April and January — swimming for long without one gets cold. In early November just a light top is enough for sun protection, water is almost always around +27°C.

In May water is around 24-25°C — swimming for an hour or more can feel cold without a wetsuit. A rash guard, leggings, and a headband/buff help; in September just a rash guard should be enough.
