When to Visit
Mar-May
Nowruz New Year on March 21 brings two weeks of pilgrimage to Persepolis, and Isfahan and Shiraz at peak with rose blooms across Kashan.
Jun-Aug
Yazd and Isfahan hit 40°C, central plateau punishing, but the Caspian coast and Tehran's Damavand high country stay cool.
Sep-Oct
Pomegranate and date harvests, Yazd and Persepolis at their most pleasant, and the photographic light at Naqsh-e Jahan at year-best.
Nov-Feb
Cool to cold across the plateau, snow possible in Tehran, and Isfahan's bridges atmospheric in winter mist with bath culture indoors.
