Weather in Isfahan

Find out the current weather conditions in the city of Isfahan. Below, you will find up-to-date data, forecasts, and visual meteorological charts to help you plan your day.

The climate in Isfahan is characterized as arid with distinct seasons. The city is known for its hot, dry summers and cool, sometimes cold winters. Spring and autumn serve as transitional periods when temperatures change gradually, offering more moderate weather.

One of the main climatic features of Isfahan is the extremely low amount of rainfall throughout the year. Most months pass practically without rain, which is especially noticeable during the summer period from June to September, when precipitation and rainy days are virtually absent. In winter, from December to February, average temperatures fluctuate around 3-6°C, while minimum values can drop below freezing. In summer, especially in July and August, the average temperature rises to 28-29°C, and maximum daytime temperatures regularly exceed 35°C.

Therefore, tourists planning a trip to Isfahan should take into account significant seasonal temperature fluctuations. For summer months, light clothing and sun protection are recommended, whereas a winter visit will require warm clothing. Regardless of the season, the likelihood of encountering rain is minimal, making Isfahan an attractive destination for lovers of sunny weather.

The climate in Isfahan is characterized by significant annual temperature fluctuations, which is typical for its geographical location. The hottest month is usually July, when the average temperature is about 29.4°C, and daytime highs regularly reach 37.1°C and above. June and August are also very hot, with average temperatures of 27.4°C and 27.8°C respectively. Conversely, the coldest month is January, with an average temperature of just 3.2°C. During this period, night temperatures often drop below freezing, averaging down to -3.3°C, indicating the possibility of frost.

Summer months in Isfahan, from June to August, are distinguished by intense dry heat. The daytime heat can be exhausting, with temperatures consistently exceeding 35°C. However, thanks to the very low humidity, confirmed by the almost complete absence of precipitation during this period (0 mm of rainfall and 0 rainy days from June to September), the heat feels somewhat more bearable than in high humidity conditions. Nights bring substantial relief: air temperature can drop to 19-22°C, creating a significant diurnal temperature variation.

Winter in Isfahan, covering December, January, and February, is quite cool. Average daytime temperatures range from 9.7°C in January to 13.3°C in February. Night frosts are a common occurrence, especially in January, when the average minimum is -3.3°C, and in December (-1.3°C). An important feature of Isfahan's climate throughout the year is the substantial difference between day and night temperatures. This diurnal range often exceeds 10-15°C, which is particularly noticeable not only in summer but also in the transitional seasons – spring and autumn, when warm days can be followed by quite cold nights.

An arid climate prevails in Isfahan, reflected in the extremely low level of precipitation throughout the year. A distinct dry season is observed from June to September, when rains are almost completely absent, and the number of days with precipitation tends toward zero. Even in October, the probability of precipitation is minimal, with only one such day noted on average.

A slight increase in rainfall occurs during the cooler period, roughly from November to April. However, even in these months, the volume remains insignificant, usually not exceeding 1 mm. In the coldest months, such as January, February, and December, when night temperatures can drop below freezing, this meager precipitation may fall as light snow or frost. For example, in February and November, about 1 mm of precipitation and approximately 4-5 days with it are registered, while in January and December, with 3 days of precipitation, the amount is recorded as 0 mm, indicating trace values.

The highest frequency of days with precipitation, albeit with minimal amounts, is observed in April – averaging about 6 days, with about 1 mm falling. February, March, and November also demonstrate similar figures with 1 mm of precipitation and 4-5 days with it. Overall, Isfahan is a city where precipitation is a rare phenomenon, and sunny weather prevails for most of the year, making the summer months (June-September) the driest, and the period from February to April and November relatively "wetter," if one can use that term for such small values.

When planning a trip to Isfahan, it is important to consider the significant temperature fluctuations throughout the year. In summer, especially from June to August, when the average temperature rises above 27°C and the maximum can reach 35-37°C with virtually no rainfall, you will need light, breathable clothing made of natural fabrics such as cotton or linen. Do not forget high SPF sunscreen, sunglasses, and a hat for protection against the intense sun. Comfortable walking shoes are absolutely essential, as you will likely spend a lot of time exploring the sights.

In the transitional seasons, spring (March-May) and autumn (September-November), the weather in Isfahan is more moderate but still requires a careful approach to wardrobe choices. It can be warm during the day, especially in May and September, but evenings and mornings can be cool. The principle of layering comes in handy here: pack T-shirts, light sweaters or a fleece jacket, as well as a windbreaker or light jacket. Although the amount of precipitation is low, rainy days do occur in spring and November, so a compact umbrella or light raincoat may be useful.

Winter in Isfahan (December-February) is quite cold, with average temperatures from 3°C to 6°C, and night frosts are not uncommon. You will definitely need warm items: sweaters, a warm jacket or coat, a hat, gloves, and a scarf. Despite heavy snowfall or torrential rains being unlikely (precipitation is minimal, but there are 3-4 "wet" days), warm and comfortable clothing will make your stay in the city much more pleasant. Layering is also relevant to adapt to the temperature difference between indoors and outdoors.
