One of the key features of the weather in Rasht is the high number of days with precipitation throughout the year, although the monthly amount of rainfall in millimetres is not always high. This indicates frequent, but often light, rains. The highest number of rainy days (15-16 per month) and the peak in rainfall amount (6-7 mm) occur during the autumn months, especially in October and November. The summer months, particularly June and August, are the driest both in terms of rainfall amount (1-2 mm) and the number of rainy days (6-7 days), offering more sunny periods. Nevertheless, even in summer, there remains a likelihood of brief showers, maintaining the region's overall humidity.

In Rasht, precipitation is distributed unevenly throughout the year, with a distinctly wetter period from autumn to early spring and a drier summer. Although the total amount of precipitation in the city is not large, rainy days occur regularly throughout the year.

The wettest time of the year is autumn and the beginning of winter. November receives the highest amount of precipitation, averaging about 7 mm, which is spread over approximately 15 rainy days. October, in turn, is characterized by the maximum number of days with precipitation – about 16, with approximately 6 mm falling. In general, from September to March, rainfall ranges from 3 to 5 mm per month, and it rains for 12 to 15 days each month. Given the temperature regime of Rasht, this precipitation falls predominantly as rain.

The summer months, from June to August, as well as late spring (April-May), are the driest. June is the least rainy month, with only about 1 mm of precipitation and an average of 6 rainy days. In the other months of this period (April, May, July, August), about 2 mm of precipitation falls, and the number of rainy days varies from 7 to 11. Thus, although Rasht does not experience heavy downpours, light or moderate rains are a characteristic feature of its climate, especially in the autumn-winter period.

When planning a trip to Rasht, it is important to consider its humid subtropical climate with distinct seasons. Winter (December-March) here is quite mild but cool, with average temperatures from 8°C to 11°C and frequent, though not heavy, precipitation (averaging 12-15 rainy days per month). Therefore, during this period, it is worth bringing warm layered clothing: sweaters, a fleece jacket, a waterproof jacket or coat, as well as a hat, scarf, and gloves. Do not forget an umbrella or raincoat. In spring (April-May), the weather becomes warmer, with average temperatures rising to 14-19°C, but rain is still possible. A light jacket, jumpers, and comfortable closed shoes will be very useful.

Summer in Rasht (June-August) is hot and humid, with average temperatures of 23-26°C, sometimes reaching 28-29°C. Rainfall is minimal, but humidity can be high. For this season, choose light, breathable clothing made from natural fabrics. T-shirts, light trousers or long skirts, and sandals are your main wardrobe. Be sure to bring sunscreen, a hat, and sunglasses. Autumn (September-November) brings a gradual cooling (average temperatures from 23°C in September to 14.5°C in November) and an increase in precipitation, especially in October and November, which are the rainiest months. The principle of layering is relevant again: t-shirts, shirts, sweaters, a demi-season jacket, and, of course, an umbrella or raincoat. Regardless of the season, comfortable walking shoes are a must-have in your suitcase.

Considering the cultural customs of Iran, tourists are recommended to choose modest clothing. For women, this means covering the head (headscarf or scarf) and wearing loose clothing that covers arms to the wrists and legs (long tunics, cardigans, trousers, or long skirts). Men should also avoid shorts and overly revealing tank tops in public places. When selecting a wardrobe, give preference to items that are easy to combine with each other, creating layered looks to adapt to weather changes throughout the day.
