Het weer in Shiraz (Persepolis) in september

Forum posters consistently rate October as an ideal time to visit Shiraz, describing conditions as mild - not cold, and definitely not warm - with posters specifically preferring October over November since it runs cooler and more comfortable overall. Posters describe autumn arriving in September still warm and sunny, with conditions mellowing further as October progresses. Posters also flag October's timing after school holidays end as a genuine bonus, meaning noticeably fewer domestic crowds than the summer and early-autumn peak. Posters generally rate October as one of the best, most balanced months to visit Shiraz, combining pleasant temperatures with lighter crowds.

Spring and autumn are the forum's seasons for Shiraz, and April is the pick of them: near 24°C by day, 12 at night, sunny and warm enough for cotton clothes with a lightweight showerproof layer for the evenings. April is also orange-blossom season here, with the rose-water distillation ceremonies falling around the same time. The booking advice is precise: Nowruz, the Iranian New Year around 21 March, fills hotels solid from about 10 March to 5 April. Mid-April, once the holiday is over, is the sweet spot — pleasant weather, rooms available, no queues at the landmarks.
