Egypt's climate varies significantly between its Mediterranean north, Nile Valley interior, and desert regions, but the overriding pattern is clear: October to April is the best time to visit, particularly for the ancient sites in Cairo, Luxor, and Aswan. Summer (May–September) brings genuinely dangerous heat in Upper Egypt and the desert, with temperatures regularly exceeding 45°C in Luxor.

Summer (May–September) brings genuinely dangerous heat in Upper Egypt and the desert, with temperatures regularly exceeding 45°C in Luxor.
Peak Season (October–February): Best for Nile Valley
The core tourist season for Egypt's Nile Valley runs October through February. Temperatures in Luxor drop to a comfortable 28°C (October) through 22°C (January), making outdoor temple exploration possible throughout the day. Aswan is similarly pleasant — warm, dry, and clear. Cairo in winter is mild (15–22°C) with occasional cool, overcast days. December and January are Egypt's busiest months for international tourism — booking Nile cruises, guided tours, and hotels well in advance is essential. The crowds at the Karnak Temple and Valley of the Kings can be significant in high season — plan for early morning visits (gates open at 6am) before the tour groups arrive.
Shoulder Season (March–May and September–October)
March and April offer a short but excellent window — temperatures are rising (Luxor reaches 35°C by April) but remain manageable, the crowds thin slightly from the February peak, and spring wildflowers appear in the Sinai and Mediterranean coast regions. September and October mark the end of the brutal summer — October is particularly good, with temperatures retreating to comfortable levels in Luxor (34°C) while remaining among the warmest months at the Red Sea resorts.
Summer (May–September): Avoid Upper Egypt
Summer in Egypt's Nile Valley is genuinely extreme. Luxor in June, July, and August regularly reaches 42–45°C — temperatures at which spending significant time outdoors at unshaded ancient sites risks serious heat illness. The Valley of the Kings in summer requires a 3–4am start to complete before the heat becomes dangerous. Cairo is slightly cooler (35–38°C) but air pollution and heat make it uncomfortable. Exceptions: the Red Sea coast (Hurghada, Sharm el-Sheikh) is popular year-round with package tourists as the sea breeze moderates the heat, and the Mediterranean coast (Alexandria) is at its best in summer — warm but not extreme (28–32°C).
The Red Sea: Different Rules
Egypt's Red Sea resorts operate on a different seasonal logic from the Nile Valley. Hurghada and Sharm el-Sheikh are year-round destinations for beach and diving holidays, with sea temperatures ranging from 22°C (February) to 28°C (August–September). Visibility for diving and snorkelling is outstanding year-round. Winter (November–March) is the best season for a combined Nile Valley and Red Sea itinerary — cooler and more comfortable for the ancient sites, still warm enough for the coast.
Practical Planning Notes
Egypt's peak visitor periods generate genuine logistical challenges. Nile cruise booking (Luxor to Aswan or vice versa, typically 4–7 days) should be secured 3–6 months ahead for December–February travel. The Giza Pyramids and Egyptian Museum in Cairo require early arrivals to avoid tour bus congestion. The Abu Simbel temples in the deep south (served by daily flights from Aswan) are manageable on a day trip October–April; in summer the early flight time (5am departure) is necessitated by the heat. Egypt's ancient sites generally do not provide shade — a wide-brimmed hat, sun protection, and 2+ litres of water per person per day are non-negotiable.
