This is the coolest the sea gets all year. Average sea temperature: 28°C in August, 27°C in September and 27°C in October. You can snorkel for an hour or more without feeling cold.
No wetsuit needed. A rash vest or an old T-shirt protects your back from the sun while you snorkel.
What's running in September
The sea stays warm all month and the summer crowds thin out. Tiran Island and White Island are as good as in August, and a shore dive is an easy first try at scuba with an instructor.
Days are still about 34°C, so desert trips are best at sunset. Mount Sinai is comfortable at night, and Cairo cools a little, to about 33°C.

What to pack for Sharm El Sheikh in September
- Swimwear, sunglasses and a hat
- High-factor sun cream (SPF 50): the UV index is very high, even when a breeze makes it feel cooler
- Light, loose clothes that cover your shoulders, and a refillable water bottle: in the midday heat you need to drink often
- Reef shoes or water shoes for coral beaches and rocky entries
- A fleece and a torch if you climb Mount Sinai at night, as the summit is much cooler than the coast
