What is Khamsin
The Khamsin is a very dry, hot and sandy wind that blows with great speeds from south to south-east, affecting Egypt and the eastern countries surrounding the Mediterranean Sea (also known as Levant). The name Khamsin of the wind is a local name that is more common in Egypt and is also used in the Levant such as in Israel, Jordan, Palestine, etc. The wind may also be called Chamsin, Hamsin, or the more popular word of Egypt - Khamaseen. The meaning of the word Khamsin comes from the Arabic and Arabic dialects meaning “fifty” which refers to the fifty day period during which the Khamsin blows over the region.
Characteristics of the Khamsin
The Khamsin, as is clear from the introduction, is a dry and sand-filled windstorm blowing over Egypt for a period of 50 days in the spring season. In Levant, it takes a different form as it blows in both the spring and the autumn. Similar winds that blow in other parts of the North African region, the Arabian Peninsula and the Mediterranean basin. They have different names for the similar phenomenon such as bad-i-sad-o-bist roz in Iran and Afghanistan, haboob in Sudan, ajej in southern Morocco, ghibli in Tunis, africo in Italy, sirocco (meaning “easterly in Arabic) or sirocco dan khamsin (loosely translating to easterly flowing for fifty days), etc.
As the Khamsin passes through a given area, it carries large amounts of dust from the deserts along with it. An image of such a sandstorm is shown below in the given picture:

This windstorm or sandstorm is known to occur for over fifty days with a time interval of a few days. While it blows over a particular area, it lasts for a few hours, sometimes even for three to four days and has the following characteristics and effects over the given area:
Blowing at a speed reaching 140 km/hr along with the dust it leads to a very oppressive weather condition which can be responsible sometimes for the death of the people as well.
As it blows the humidity over the area drops below 5% causing extreme dryness in the weather and which can hinder electrical properties due to which many times the magnetic compass as well goes haywire.
The Khamsin is so hot, that even during the time of the winter season, it can cause a rise in the temperature upto 45° C because of the storm.
Within two hours it can cause a rise of 20° C in the temperature of the day.
In the Levant, it brings oppressive weather front, with hot temperatures and huge amounts of dust obstructing the visibility without any strong winds flowing during the day. Although, strong winds might occur at night.
After blowing continuously for a significant amount of time, is followed by an inflow of much cooler air.
The Khamsin is known to be caused by the extratropical cyclones that travel eastwards following the southern parts of the Mediterranean or the North African coast from February to June. In other words, the shift in the low pressure centre towards the east, over the Sahara, of the southern Mediterranean, leads to Khamsin flowing from the south to south-east. On the front side, the low pressure centre brings in the dry air, northward, out of the desert and on the rear side it brings the cool air southward from the Mediterranean.
Historical Accounts and Cultural Impacts of Khamsin
The Khamsin sandstorms have been reported to have seriously impacted the military campaigns of Napoleon in Egypt and Allied-Germany campaign in North Africa in World War II. In the case of Napoleon’s Egyptian campaign in 1798, the French had an extremely difficult time dealing with the Khamsin. The storm appeared to them “as a blood[y] tint in the distant sky”. While fighting against the Ottomans during the Khamsin, the Ottomans took cover and the French unaccustomed to the circumstances “did not react until it was too late, then choked and fainted in the blinding, suffocating walls of dust”. An image of the bloody tint is shown in an image below:

Similar difficulties were faced by the Allied-German forces during the North African campaign of World War II. “Allied and German troops were several times forced to halt in mid-battle because of sandstorms caused by the khamsin…. Grains of sand whirled by the wind blinded the soldiers and created electrical disturbances that rendered the compasses useless.”
The sandstorm has so much geographical significance that it has heavily influenced the cultural life as well. It is the Khamsin which in the Book of Exodus of the Hebrew Bible is named as the ruah kadim or the “east wind” responsible for the parting of the Red Sea.
A 19th century account of the Khamsin in Egypt, states the following:
“These winds, though they seldom cause the thermometer of Fahrenheit to rise above 95° in Lower Egypt, or in the Upper Egypt 105°, are dreadfully oppressive, even to the the natives. When the plague visits Egypt, it is generally in the spring; and the disease is most severe in the period of Khamáseen.”
From the same source it is observed that the Muslims in Egypt, “calculate the period of [Khamaseen]..., to commence on the day immediately following the Coptic festival of Easter Sunday, and to terminate on the Day of Pentecost (or Whitsunday); an interval of 49 days.” This period is the period that coincides with the Jewish Counting of the Omer, that also has the time duration of 49 days. In Israel, the Khamsin is more formally known as the sharav.
Some of the Most Recent Cultural Impacts of the Khamsin are Listed as Below:
Khamsin was the title of a 1982 Israeli film that tells the story of the clash between a Jewish landowner and his Arab workers in a small farming village in the Galilee.
“Khamsin” was the codename for one of the characters of the video game Metal Gear Rising: Revengeance.
“Khamsin” was also the name of a character Flame Haze in the anime Shakugan no Shana.
The speed aspect of the Khamsin has been taken into account while naming windy khamsin 35 and Maserati Khamsin. The windy khamsin 35 is a motor yacht produced by the company Windy. The Maserati Khamsin is a grand tourer produced by the company Maserati from 1974 - 1982. The Maserati Khamsin is the common result when searched for lamborghini khamsin. The lamborghini khamsin, one of the common searches for fast cars on google displays the information regarding the Maserati.
The Khamsin has also been depicted in one of the stories of the adventures of Tintin.
FAQs on Khamsin
1. What is the Khamsin wind?
Khamsin is a local seasonal wind that is characteristically hot, dry, and laden with dust and sand. It originates over the Sahara Desert and blows across North Africa, primarily affecting Egypt and the eastern Mediterranean basin. This wind is associated with a significant rise in temperature and a drop in humidity, often reducing visibility due to the suspended dust particles.
2. What does the name 'Khamsin' mean?
The name 'Khamsin' (خمسين) is derived from the Arabic word for “fifty”. This refers to the approximate fifty-day period in the spring, typically from March to May, during which this wind is most likely to occur. While the wind does not blow continuously for 50 days, this period marks its active season.
3. What meteorological conditions cause the Khamsin wind?
The Khamsin is typically triggered by low-pressure systems or depressions that move eastward across the Sahara Desert or the southern Mediterranean Sea. As these depressions travel, their cyclonic circulation pulls hot, dry air from the deep desert interior northwards. This air mass picks up vast quantities of sand and dust as it moves, leading to the characteristic sandstorm conditions when it arrives in regions like Egypt.
4. Which regions are primarily affected by the Khamsin wind?
The Khamsin most famously affects Egypt. However, its influence extends to other parts of North Africa and the Levant. The regions affected include:
Egypt (primary region)
The Sinai Peninsula
Israel and Palestine (where it is known as Sharav)
Jordan, Syria, and Lebanon
5. What are the major impacts of the Khamsin on the environment and daily life?
The Khamsin has several significant effects. The oppressive heat and dust can cause respiratory problems and general discomfort for people. Visibility can be reduced to near zero, disrupting air and road transport. Furthermore, the hot, dry wind can damage crops by desiccating plants and can also increase the risk of wildfires in the regions it affects.
6. How does the Khamsin differ from other desert winds like the Sirocco?
Both Khamsin and Sirocco are hot, southerly winds originating from the Sahara. The key difference lies in their primary path and the regions they affect. The Khamsin is primarily an eastern phenomenon, affecting Egypt and the Levant. In contrast, the Sirocco is a term more commonly used for the same type of wind when it travels north across the central Mediterranean to affect Southern European countries like Italy, Malta, and Croatia. While both are born from the same desert, their names change based on the location they impact.
7. Does the arrival of a Khamsin wind signal a permanent change in weather?
No, a Khamsin event is a temporary weather phenomenon, typically lasting for a few hours to a few days. It is often a harbinger of change. The passing of the low-pressure system that causes the Khamsin is usually followed by the arrival of a cold front, which brings cooler, clearer, and more humid air from the Mediterranean, providing relief from the oppressive heat and dust.
