The Big Picture
Understanding Egypt's Climate
Egypt has, in effect, two seasons that matter to a visitor: a long, intensely hot summer from roughly May to September, and a mild, dry winter from October to April that constitutes the high season for heritage travel. The further south you go, the more extreme the heat becomes, so Aswan and Abu Simbel in midsummer can climb well above forty degrees Celsius, while Cairo and the Mediterranean coast stay a few degrees cooler and slightly more humid. Rain is rare almost everywhere and never disrupts a heritage itinerary in the way it might elsewhere.
For most travellers the sweet spot runs from late October to early April, when daytime temperatures are comfortable for walking open-air sites and the evenings are pleasantly cool. This is also when the crowds and prices peak, so the trade-off for good weather is sharing the Valley of the Kings with more visitors and booking accommodation further ahead. Our advice on pacing hot-weather days appears in the Visitor Handbook, which is essential reading if your dates fall in the shoulder months.
One desert phenomenon worth knowing is the khamsin, a hot, dust-laden wind that can blow for a day or two between March and May, reducing visibility and making outdoor sites uncomfortable. It passes quickly, and a flexible day or two in your itinerary lets you simply switch to indoor museums when it arrives.
