Why Egypt rewards careful timing.
Egypt's climate is a textbook hot desert. Cairo averages 32–35°C in July–August and lower 20s in December–January; Luxor and Aswan, deeper in the Nile valley, run 3–5°C hotter at every season. The country gets almost no rain, the entire coastline and Nile valley are climatologically arid. Sun, dust, and heat are the variables; rain barely matters.
Summer is genuinely punishing for sightseeing. The Valley of the Kings tombs are unventilated and unair-conditioned, by midday in August, interior temperatures push 45°C with high humidity from visitor breath. The Pyramid plateau at Giza is exposed sun without shade. Karnak and Luxor temples are sprawling open-air sites. Most experienced visitors only come mid-October through mid-April for the Nile cultural circuit. Most Nile cruise operators reduce summer schedules or close entirely from June through August.
The Red Sea is the year-round counterweight. Hurghada (the largest resort), Sharm el-Sheikh (more upscale, on the Sinai), Marsa Alam (further south, quieter), and Dahab (laid-back, backpacker-favored) sit on a 6,000+ km² coral-reef coast with diving infrastructure rivaling the Caribbean. Air temperature is 24–35°C across the year; sea is 22°C in winter, 28°C in summer. Diving is genuinely year-round with no off-season. Most travelers tack 3–5 nights of Red Sea on at the end of a Nile trip.
Ramadan 2026 (Feb 17 – Mar 18) changes the rhythm of Cairo and Luxor non-tourist neighborhoods. Tourist sites and Nile cruises operate normally, staff are accustomed to non-Muslim visitors and meals continue. Restaurants in non-tourist areas may close midday or shorten hours. Iftar (sunset) is genuinely beautiful, Cairo's Khan el-Khalili comes alive after dark, families eat together, and the city's atmosphere is at its richest in the late evening. Eid al-Fitr (March 19–20, 2026) sees major closures and family travel; Eid al-Adha (around May 27, 2026) is similar.
The Khamsin (Arabic for 'fifty', because it traditionally blows for fifty days) is a hot, dust-laden wind sweeping in from the Western Desert during March–May. Most days are normal; on Khamsin days, visibility drops sharply, dust covers everything, and outdoor visits to the Pyramids or open-air temples become unpleasant. Build flexibility into your March–April itinerary to swap a Khamsin day for an indoor museum day.
The Grand Egyptian Museum (GEM) at Giza fully opened in November 2024 after multiple delays, the world's largest archaeological museum dedicated to a single civilization, housing the entire Tutankhamun collection (over 5,000 objects) for the first time. The original Egyptian Museum at Tahrir Square remains open with reduced collections. GEM is the new headline draw alongside the Pyramids.
