Weather in Ahvaz

Planning a trip to Ahvaz or just want to stay updated on weather conditions? In this section, you will find up-to-date weather information, as well as detailed forecasts and useful charts.

The climate in Ahvaz, located in Iran, is characterised as arid and hot. The city experiences extremely high temperatures in the summer and mild winters. Temperature fluctuations between seasons are significant, which is typical for a desert climate.

Two main seasons are clearly distinguished in Ahvaz: a very hot and dry summer and a short, mild winter. The summer months, especially from June to September, are distinguished by scorching weather, when average temperatures often exceed 35-40°C, and maximums can reach nearly 50°C. Rainfall is practically non-existent during this period. Winter, from December to February, brings more comfortable temperatures, averaging around 13-16°C, and a small amount of precipitation. Spring and autumn are short transitional periods with rapidly rising (in spring) or falling (in autumn) temperatures.

One of the most notable features of the weather in Ahvaz is its extreme aridity. For most of the year, very little precipitation falls, and from May to October, there is practically none. Even in the "wettest" months, such as November, rainfall is minimal. This makes Ahvaz one of the hottest and driest cities in the world, which is important to consider when planning a trip.

The climate of Ahvaz is characterised by significant annual temperature fluctuations, making it a city of contrasts. The hottest period falls during the summer months, especially June and July. In July, the average air temperature reaches an impressive 40.1°C, and daytime highs often rise to 48.1°C. Already in May, the average maximum temperature is around 40.3°C. Summer in Ahvaz is distinguished by intense, dry heat, since from May to October precipitation is minimal or entirely absent, creating conditions for very hot weather.

Winter months, on the contrary, offer significantly milder conditions. The coldest month of the year is January, when the average temperature holds at 13.8°C. At night, the temperature can drop on average to 8.4°C, and during the day rise to a comfortable 19.2°C. December and February are also characterised by cool, but generally pleasant weather for walking and exploring the city. The transitional seasons, spring and autumn, are distinguished by more moderate temperatures, gradually rising towards summer and falling towards winter.

One of the characteristic features of the climate in Ahvaz is the noticeable difference between day and night temperatures. For example, in July, the diurnal temperature variation can reach 16°C (from 32.1°C at night to 48.1°C during the day). Even in the cooler January, this difference is about 10.8°C (from 8.4°C to 19.2°C). This means that even after very hot days, evenings and nights can bring perceptible coolness, which is worth considering when planning activities and choosing clothes.

In Ahvaz, a very arid climate is observed with clearly defined precipitation seasons. For most of the year, there is practically no rain here. The main period when precipitation can be expected falls during the autumn-winter and early spring months, while summer is characterised by a complete absence of rain.

The dry season in Ahvaz lasts from May to October. During these months, the amount of precipitation tends towards zero: in May, June, July, August, September, and October, on average, not a single millimetre of precipitation falls. The number of rainy days during this period is also minimal – from zero in June, July, and September to one or two days in May, August, and October. This means that for almost half a year, the probability of rain is extremely low.

The relatively "wet" season falls on the period from November to April. However, even in these months, precipitation is very scanty. The "rainiest" month is considered to be November, when an average of 3 mm of precipitation falls, and there are about 7 days with precipitation. In January, March, and December, 2 mm of precipitation falls (approximately 6 rainy days), and in February and April – only 1 mm (4-5 rainy days). Given the high temperatures year-round, precipitation falls exclusively in the form of rain, which, judging by the small volumes, is most likely in the nature of light drizzle or brief weak showers.

When planning a trip to Ahvaz, it is important to consider its hot desert climate. For most of the year, especially from April to October, high temperatures prevail here, reaching a peak in the summer months (June-August), when the thermometer regularly rises above 40-45°C. Therefore, the basis of your wardrobe should be light, loose clothing made of natural breathable fabrics, such as cotton or linen. Be sure to bring sunscreen with a high SPF, a wide-brimmed hat or cap, as well as sunglasses. Given the cultural features of Iran, women are recommended to have a headscarf or shawl to cover their head and to choose clothes that cover their arms and legs.

Winter months in Ahvaz (from December to February) are significantly milder, with average temperatures around 13-16°C, but nights can be cool (8-10°C). During this period, the principle of layering will come in handy: t-shirts, long-sleeved shirts, a light sweater or fleece jacket, as well as a windbreaker or light jacket. Precipitation in Ahvaz is extremely rare throughout the year; even in the "wettest" months (November-March), the number of rainy days is small, and only a few millimetres of precipitation fall. Thus, a heavy umbrella or raincoat is unlikely to be needed, but an ultralight folding umbrella can be taken just in case for the winter months.

Regardless of the season, comfortable closed-toe shoes for walking are an absolute necessity, as you will be walking a lot while exploring the city. A light scarf may also be useful, which will protect you from the sun during the day or from the evening chill. Do not forget a personal first aid kit and, perhaps, moisturising cream, as the air can be dry, especially during the hot months.
