Weather in Ilam

Planning a trip to Ilam? Here you will find the latest information on current weather, as well as detailed forecasts and charts to help you better prepare for your journey.

Ilam's climate can be described as mountainous semi-arid, with distinct contrasts between seasons. The weather here shifts from hot and dry summers to cool and relatively humid winters, creating diverse travel conditions throughout the year. Thanks to its location in a mountainous area, the climate possesses unique features that distinguish it from the country's hotter desert regions.

The summer months, particularly July and August, are characterised by high temperatures, which can exceed 36°C during the day, and an almost total absence of rainfall. This is a time of scorching sun and consistently clear skies. Conversely, winter brings coolness: the average temperature in January hovers around 4°C, and slight frosts are possible at night. It is the winter period and early spring that account for the highest number of rainy days.

Spring and early autumn are considered the most comfortable periods for most tourists in Ilam. During this time, pleasant, moderate weather sets in, when it is no longer cold but the summer heat has not yet arrived. Spring months are particularly good for exploring the region's nature, as the surroundings come to life after the winter rains, and the air temperature is ideal for walking.

The climate of Ilam is distinguished by pronounced seasonality, offering travellers diverse weather conditions depending on the time of year. The annual temperature range here is quite wide: from the winter chill, when average figures in January are around 4.4°C, to true summer heat. The hottest month is traditionally July, when the average temperature rises to 29.3°C, creating a stark contrast compared to the beginning of the year.

Summer in this region of Iran is usually hot and dry. In peak months, such as July and August, daytime maximums often reach 36-37°C. Precipitation is practically non-existent during this period, guaranteeing clear skies but requiring tourists to use sun protection and stay hydrated. Spring and early autumn, on the other hand, delight with milder and more comfortable warmth, with temperatures staying in a pleasant range from 15°C to 25°C.

The winter period is characterised by cool, and sometimes frosty weather, especially at night. In January, night-time temperatures can drop below freezing (averaging down to -0.6°C), although during the day the air often warms up to 9-10°C. It is worth noting the daily temperature fluctuations characteristic of the region: the difference between daytime warmth and night-time chill can be significant, so layering clothing will be the best choice for comfortable walks around the city.

The climate in Ilam is characterised by a clear division into dry and wet seasons, which is important to consider when planning a trip. The summer months, as well as the beginning of autumn, are an absolutely arid period: according to statistics, from June to September the probability of precipitation is practically zero. This time of year guarantees tourists clear skies and no rain, which is ideal for lovers of sunny weather.

The bulk of moisture arrives in the region during the cold season and early spring. The "wettest" month in terms of precipitation frequency is considered to be March, when about 12 rainy days are recorded. In winter, especially in January and February, the weather is also often overcast (10–11 days with precipitation per month). Considering that in January the average minimum temperature drops below zero, not only rain but also snow or sleet is quite likely during this period.

Transitional periods, such as April and November, retain moderate humidity — precipitation falls on average 9 days a month. However, by May the number of rainy days noticeably decreases, heralding the onset of the dry summer. In general, even in the wet season, precipitation here is usually moderate, so having waterproof shoes and an umbrella will make walking around the city quite comfortable.

When packing for Ilam, it is important to consider the distinct seasonality of this region. Summer here is hot and arid, with temperatures often exceeding 30°C, so for a trip from June to September, choose light, loose clothing made from natural breathable fabrics. Since rain is extremely rare during this period and the sun is very active, be sure to bring a hat, sunglasses, and high SPF sunscreen.

In winter and early spring, the weather changes: it becomes cool, and night-time temperatures can drop slightly below freezing. From December to March, the highest number of days with precipitation is observed, so a warm jacket, cosy sweaters, and waterproof shoes will be essential. We also recommend packing a compact umbrella or raincoat to be ready for nature's whims.

In transitional seasons, such as April or October, the layering principle in clothing will be the best solution. During the day it may be warm enough for a T-shirt or light shirt, but by evening the air cools quickly. Regardless of the time of year, put comfortable and sturdy walking shoes in your suitcase to explore the city streets and surroundings with comfort.
