Siwa Oasis sits 13 to 15 meters below sea level in the Western Desert. Planning your visit around the seasons is critical for a safe trip. The summer months bring extreme heat that makes outdoor activities dangerous.
What is the best time of year to visit Siwa Oasis?
The ideal window is between October and April during autumn, winter, and spring.
Temperatures during these months are comfortable for exploring sites like the Shali Fortress and the Mountain of the Dead. You can safely swim in the hypersaline salt lakes and Cleopatra's Spring without risking heat exhaustion.
Can you visit Siwa Oasis in the summer?
You should avoid traveling to Siwa during the summer months.
Between May and September, the Western Desert experiences intense, dangerous heat. Desert safaris into the Great Sand Sea become physically exhausting. The direct sun also makes exploring the open archaeological sites difficult.
How cold does Siwa Oasis get in winter?
Daytime temperatures are mild, but winter nights in the desert get surprisingly cold.
If you visit between December and February, pack a light jacket or fleece for the evenings. The temperature drops sharply after the sun sets over Fatnas Island. Daytime remains pleasant enough for outdoor tours and walking.
Does the weather affect Great Sand Sea safaris?
Yes, extreme heat makes desert safaris dangerous.
You need a military permit handled by local operators to enter the Great Sand Sea. Safari operators prefer running 4x4 dune bashing and sandboarding trips during the cooler months. You will spend hours in an open desert environment with little shade.
What clothing should I pack for Siwa Oasis?
Pack modest clothing for town and layers for the shifting desert temperatures.
- Modest clothing covering shoulders and knees for town visits.
- A light jacket or fleece for cold desert nights.
- A wide-brimmed hat, sunglasses, and sunscreen for daytime sun.
- A swimsuit for the salt lakes and hot/cold natural springs.
Does the weather affect the salt lakes?
The water in the salt lakes remains cool, but the high salt concentration draws heat from the sun.
You can still float effortlessly in the hypersaline pools during the winter. After getting out, dry off quickly with a travel towel, as the winter breeze can feel chilly. You can warm up afterward at Bir Wahed, a sulfuric hot spring in the dunes.
Questions travellers ask
How long should I stay in Siwa Oasis?
We recommend booking a multi-day trip of 3 to 5 days. This gives you enough time to rest after the 9 to 12-hour drive from Cairo.
Can you swim in the Siwa salt lakes?
Yes, you can float effortlessly due to the intense salt concentration. Bring water shoes to protect your feet from sharp salt crystals, and avoid splashing your eyes.
What is the best time to see the sunset at Fatnas Island?
Arrive at least an hour before sunset. The cooler months of October to April provide clear skies for watching the sun drop over the water.
