Red Sea Egypt Weather: When Is the Best Time to Swim?
Understanding the weather in Red Sea Egypt can help you choose the right time for your vacation.
The Egyptian Red Sea coast is famous for sunshine, warm temperatures, clear water, and a very long swimming season. Destinations such as Hurghada, Sharm El Sheikh, Marsa Alam, and El Gouna attract travelers throughout the year.
But the best time to swim depends on what you mean by "best."
Do you want the warmest water? The most comfortable air temperatures? Fewer crowds? The best conditions for snorkeling and diving?
This guide breaks down the weather in Red Sea Egypt and explains when American travelers should plan their beach vacation.
What Is the Climate Like Along the Red Sea?
The Egyptian Red Sea coast has a hot desert climate.
Rain is extremely limited, while sunshine is abundant throughout the year.
This makes the region very different from Mediterranean beach destinations, where winter can bring cooler weather and seasonal closures.
Current travel guides describe the Red Sea coast as a year-round beach destination, with October through May generally offering the most comfortable combination of temperatures and outdoor conditions.
Red Sea Weather in Winter
December
December is a popular time for winter-sun vacations.
Daytime temperatures are generally comfortable for sightseeing and outdoor activities, while evenings can feel cooler.
The sea remains suitable for swimming, although some travelers may prefer a wetsuit for longer snorkeling or diving sessions.
January
January is one of the coolest months, but the Red Sea is still much warmer than many winter destinations in the United States.
This makes Hurghada and Sharm El Sheikh attractive for Americans looking to escape cold winter weather.
Sharm El Sheikh can be particularly appealing during winter because parts of the destination are sheltered by the surrounding Sinai landscape.
February
February remains mild and sunny.
The water is cooler than during summer but remains suitable for swimming for many visitors.
Divers and snorkelers who are sensitive to cooler water may prefer a wetsuit.
Red Sea Weather in Spring
March
March is one of the first months when temperatures begin becoming noticeably warmer.
It can be an excellent time for travelers who want to combine swimming with sightseeing.
You can spend time at the beach without dealing with the extreme heat of midsummer.
April
April is one of the most comfortable months for a Red Sea vacation.
The weather is warm enough for swimming and beach activities while remaining manageable for excursions.
It is also a good month for travelers who want to combine the Red Sea with Cairo or Luxor.
May
May marks the transition toward hotter summer conditions.
The sea is becoming warmer, while daytime temperatures rise.
For many travelers, this is an excellent month for swimming and snorkeling because both the air and water are warm.
Red Sea Weather in Summer
June
June is hot, but the Red Sea remains extremely attractive for beach vacations.
The sea is warm, and swimming can be comfortable throughout the day.
The main consideration is the intensity of the sun and daytime heat.
American travelers should plan outdoor activities early in the morning or later in the afternoon when possible.
July and August
July and August are the hottest months.
Temperatures can become extremely high, particularly away from the water.
The advantage is that the Red Sea itself is very warm.
For travelers whose main goal is swimming, snorkeling, diving, and relaxing at a resort, summer can still be enjoyable.
However, travelers planning extensive sightseeing in Cairo or Luxor may find the heat challenging.
Red Sea Weather in Fall
September
September remains hot, but temperatures gradually become more manageable.
The water is particularly warm following the summer months.
For beach travelers, this can be an excellent period.
October
October is one of the best overall months for the Red Sea.
Air temperatures become more comfortable while the sea remains warm.
This combination makes October particularly attractive for:
-
Swimming
-
Snorkeling
-
Scuba diving
-
Boat trips
-
Desert excursions
-
Resort vacations
November
November continues the comfortable fall weather.
The sea remains warm enough for swimming, while the air is generally much more pleasant than during the summer.
For many travelers, November is an excellent balance between beach weather and comfortable sightseeing.
Red Sea Water Temperature Throughout the Year
Water temperatures vary by season and destination.
In general, the Red Sea is cooler during winter and reaches its warmest levels during late summer.
For example, climate data for Sharm El Sheikh shows average sea temperatures ranging from roughly the low 20s Celsius in winter to around 28–29°C in the hottest summer months.
For swimmers who dislike cooler water, summer and early fall offer the warmest conditions.
For travelers who want comfortable weather for sightseeing as well as swimming, spring and fall are often the better compromise.
Sharm El Sheikh vs Hurghada Weather
Both destinations offer excellent beach weather, but there can be differences.
Sharm El Sheikh
Sharm El Sheikh is known for relatively calm and clear waters, particularly in sheltered bays.
It can be an excellent choice for winter snorkeling and diving.
Hurghada
Hurghada generally has excellent swimming conditions but can experience more wind.
This can be a disadvantage for some snorkeling trips but an advantage for windsurfing and kitesurfing.
The two destinations have broadly similar sea temperatures, with winter water around the low 20s Celsius and summer water reaching the upper 20s.

These months offer some of the warmest sea temperatures.

You get warm water and comfortable conditions without the worst summer heat.

For most travelers, yes.
There is no traditional winter shutdown of Red Sea beach tourism.
Hotels and resorts operate throughout the year, and swimming, snorkeling, and diving remain major activities even during the cooler months.
The biggest difference is not whether you can swim, but whether the water and air temperatures match your personal comfort level.
Best Time for Americans to Visit the Red Sea
For American travelers, October through May is often an excellent period because it combines pleasant beach weather with more comfortable conditions for exploring Egypt's historical attractions.
A trip could include:
Cairo → Luxor → Hurghada or Sharm El Sheikh
You can explore the Pyramids and ancient temples before finishing the vacation with several days of swimming and relaxation.
If you only want a resort vacation, summer can work very well as long as you are comfortable with high temperatures.
