Best Time to Visit Iran
Last verified: 2026-06-29
Spring (mid-March to May) and autumn (September to November) are the sweet spots, with mild weather across most of the country. Summers are punishing in the central deserts and the south, while winters suit skiing near Tehran and warm escapes on the Persian Gulf. Watch the calendar: Nowruz (Persian New Year, around 21 March) brings beautiful celebrations but packed transport and closures, and Ramadan changes daytime eating and opening hours.
Key things to know
- Best overall: spring (mid-Mar-May) and autumn (Sep-Nov)
- Avoid central deserts in high summer - extreme heat
- Nowruz (~21 Mar): festive but crowded, with transport and sites booked out
- Ramadan shifts food and opening hours - plan around it
- Winter: ski near Tehran or head to the warm Persian Gulf coast
