In the evening, when it's light... And when is it light in Egypt in the evening??)) Seriously, I returned at night from Sharm. Creams +50 and coconut oil. Only under an umbrella! The sea is comfortable, sometimes hot))) The wind saves a lot - it's not stuffy. Afraid of burning in the sea - t-shirt. More water, less alcohol. Have a nice rest!
Heat is easily tolerated, dry air. Although a couple of evenings it was stuffy.
