Väder i Aswan i september

Forum posters describe August as one of the hottest months in Upper Egypt, with daily highs commonly cited in the mid-to-high 40sC and posters noting Aswan's dry heat, unlike more humid parts of Egypt, means you're dealing purely with the temperature itself rather than added humidity. Posters consistently recommend building a day around the heat rather than against it: an early dawn start for sightseeing, retreating indoors or somewhere air-conditioned by midday, and resuming outdoor activity only once things cool off in late afternoon. Posters recommend loose, long, natural-fiber clothing like thin cotton as the practical uniform for this kind of heat. Posters generally rate August as extremely hot but genuinely manageable for an Aswan visit given consistently clear skies, disciplined early starts and enough water and shade breaks.

February in Aswan is the desert winter: about 25°C by day and 10 at night, with no rain at all in the record. That spread is the whole story — the forum's repeated warning is that it can be genuinely chilly in the early morning and the evening even when the afternoon is warm and sunny, which catches Nile-cruise passengers out on deck. One traveller describes a stiff breeze on the run back from Aswan, then warmth enough by the last day to shelter under the awnings. The regulars' timing advice: the end of February into early March is cheaper and dodges the Egyptian holidays.
