Traveller notes on Marsa Alam in September
Other months in Marsa Alam
Marsa Alam's forum flags April for occasional Khamsin sandstorms, the same warm spring wind that sweeps other parts of Egypt this time of year, though regulars still rate mid-March to mid-April as one of the two best windows of the year — warm without being at the summer's full intensity. Sunshine is reliable and the sea is already comfortable for long swims.
