The driest period occurs during the summer months. From June to September, Khorramshahr typically sees no precipitation at all (0 mm) and zero rainy days.

A small amount of precipitation usually falls between November and March. November can be considered the "wettest" month, with an average of about 2 mm of rainfall spread over approximately 5 days. In January, February, March, and December, the amount of precipitation is about 1 mm per month, with around 4 rainy days.

When planning a trip to Khorramshahr, it is important to consider its hot desert climate. Regardless of the time of year, your luggage should include comfortable walking shoes, sunscreen with a high SPF, sunglasses, and a head covering (such as a wide-brimmed hat or cap) for protection from the intense sun. Given the cultural context of Iran, it is recommended to choose modest, conservative clothing: for women, loose-fitting long-sleeved blouses, long skirts or trousers, and a headscarf; men should also opt for trousers and shirts that cover the shoulders in public places.

The summer months in Khorramshahr, roughly from April to October, are characterized by very high temperatures, often exceeding 40°C, and a near-total absence of rain. During this period, choose clothing made from lightweight, breathable natural fabrics, such as cotton or linen, in light colors. A loose fit will help you cope with the heat more easily. Don't forget to drink plenty of water to avoid dehydration.

Winter, lasting approximately from November to March, brings more moderate temperatures: days can be pleasantly warm (around 14-22°C), but evenings and nights become cooler (8-16°C). At this time of year, layering is the ideal solution. Bring T-shirts, long-sleeved shirts, as well as a light jacket, sweater, or fleece for evening walks. Although rainfall is minimal even in winter (just a few days with light rain, especially in November), a lightweight folding umbrella or a compact raincoat might be useful but is not an absolute necessity.
