How Long Does Turbulence Last? A Detailed Look

If you’ve ever experienced unexpected bumps and jolts while flying on an airplane, you’ve felt turbulence. Turbulence can range from minor vibrations to violent jolts that can fling unrestrained passengers from their seats. So how long does turbulence typically last?

Here’s a quick answer: Most turbulence patches last 5 to 10 minutes, though rough patches can persist for 30 minutes or longer in rare cases.

In this comprehensive guide, we’ll take an in-depth look at the causes of turbulence, the different types and intensities, and how long you can expect turbulence to last in different flight scenarios. We’ll also provide tips on staying safe if your flight hits a rough patch.

What Causes Turbulence?

Turbulence is a common occurrence during flights and can sometimes be unsettling for passengers. But what exactly causes this bumpy ride? Let’s take a detailed look at the various factors that contribute to turbulence.

Thermal Turbulence

One of the main causes of turbulence is thermal turbulence, which is associated with temperature variations in the atmosphere. As the sun heats up the Earth’s surface, the air near the ground becomes warm and starts to rise.

This upward movement of warm air creates pockets of turbulence, especially on hot summer days. Pilots often refer to this type of turbulence as “thermals.” While thermals can be a bit uncomfortable, they are generally short-lived and not considered dangerous.

Clear Air Turbulence

Clear Air Turbulence (CAT) is another type of turbulence that can occur at high altitudes where there are no visible clouds. Unlike thermal turbulence, which is caused by temperature variations, CAT is caused by changes in wind speed and direction.

These changes can be related to jet streams, weather fronts, or even the flow of air around mountains. CAT can be quite unpredictable, and even experienced pilots can have difficulty detecting it in advance.

However, it is important to note that modern aircraft are designed to withstand CAT, and incidents of severe turbulence causing structural damage are extremely rare.

Mechanical Turbulence

Mechanical turbulence is caused by the interaction between the aircraft and the surrounding air. When an aircraft flies through areas of rough air, such as near mountains or during thunderstorms, it can experience mechanical turbulence.

This type of turbulence can be more intense and longer-lasting compared to thermal or clear air turbulence. Pilots rely on weather forecasts and onboard weather radar to avoid areas where mechanical turbulence is likely to occur.

Mountain Wave Turbulence

Mountain wave turbulence is a specific type of turbulence that occurs near mountains. When the wind encounters a mountain range, it can create a series of waves in the air. These waves can propagate downstream and cause turbulence on the leeward side of the mountains.

Mountain wave turbulence can be particularly strong and persistent, making it important for pilots to be aware of the weather conditions in mountainous regions.

How Turbulence Is Categorized

Turbulence is a common occurrence during flights and can vary in intensity. To better understand turbulence, it is categorized into different levels based on its severity. These categories help pilots, flight attendants, and passengers alike to understand what to expect during a turbulent flight.

Light Turbulence

Light turbulence is the mildest form of turbulence and is often compared to driving on a slightly bumpy road. Passengers may feel a slight jolt or experience a gentle rocking motion. It typically doesn’t pose any risk to the aircraft or passengers, and most people can continue their activities without any major disruption.

Flight attendants may still serve beverages and passengers can move around the cabin with ease.

Moderate Turbulence

Moderate turbulence is a bit more noticeable than light turbulence and can cause passengers to feel a stronger jolt or shaking. It is often described as similar to driving on a road with potholes. During moderate turbulence, flight attendants may be required to pause their service temporarily, and passengers are advised to stay seated with their seatbelts fastened.

Although it may be slightly uncomfortable, moderate turbulence is still considered safe and does not pose a significant threat to the aircraft.

Severe Turbulence

Severe turbulence is less common and can be quite jarring and unsettling for passengers. It can cause the aircraft to experience sudden and violent movements, leading to objects falling from overhead compartments and people being thrown out of their seats if they are not properly restrained.

Flight attendants will cease all service and instruct passengers to remain seated, with their seatbelts securely fastened. Pilots will also take necessary precautions to ensure the safety of the aircraft.

While severe turbulence can be alarming, it is important to remember that modern aircraft are designed to withstand such forces.

Extreme Turbulence

Extreme turbulence is the most intense and rarest form of turbulence. It can be described as violent and may cause the aircraft to be momentarily out of control. Objects can be forcefully tossed around the cabin, and passengers may be lifted from their seats.

Extreme turbulence is extremely rare, and pilots actively try to avoid areas where this type of turbulence is forecasted. Modern aircraft are built to withstand even extreme turbulence, but it is still a situation that pilots and passengers prefer to avoid.

Remember that turbulence is a normal part of flying and is usually not a cause for concern. Pilots are trained to navigate through turbulence, and aircraft are built to withstand its forces. So, the next time you encounter turbulence during a flight, rest assured that the pilots are doing their best to keep you safe and comfortable.

Typical Turbulence Duration

Light Chop (1-5 minutes)

Light chop is the mildest form of turbulence and typically lasts for 1 to 5 minutes. This type of turbulence is characterized by slight jolts and bumps, similar to driving on a bumpy road. It is usually caused by atmospheric disturbances such as wind gusts or small pockets of air turbulence.

While it may cause some discomfort, it is generally considered to be a minor inconvenience for passengers. Airlines and pilots are well-equipped to handle light chop and ensure the safety and comfort of their passengers throughout the duration.

Light Turbulence (5-10 minutes)

Light turbulence is a step up from light chop and can last for around 5 to 10 minutes. It is characterized by slightly stronger jolts and bumps, but still remains within the realm of manageable turbulence. Light turbulence can occur due to changes in wind direction, jet streams, or thermal activity.

Despite the increased intensity, it rarely poses any significant danger to the aircraft or its passengers. Pilots are trained to navigate through these conditions and maintain stability, ensuring a smooth and safe flight experience.

Moderate Turbulence (10-30 minutes)

Moderate turbulence is the next level of turbulence and can last between 10 to 30 minutes. It is characterized by more pronounced jolts and bumps, which can cause loose items to shift and passengers to feel a sense of unease.

Moderate turbulence can occur when the aircraft encounters stronger weather systems, such as thunderstorms or strong frontal systems. While it may be more uncomfortable for passengers, it is still well within the safety limits of the aircraft.

Pilots continuously monitor weather conditions and adjust their flight paths to minimize the impact of moderate turbulence on passengers.

Severe Turbulence (Short bursts)

Severe turbulence is the most intense form of turbulence and can occur in short bursts. It is characterized by violent jolts and sudden drops, which can cause objects to become airborne and passengers to experience extreme discomfort.

Severe turbulence is usually associated with severe weather conditions, such as thunderstorms or mountain wave activity. However, it is important to note that severe turbulence is relatively rare and most flights rarely encounter such extreme conditions.

Pilots are trained to avoid areas of severe turbulence whenever possible and will communicate with air traffic control to ensure a safe and comfortable flight for all passengers.

Remember, turbulence is a normal part of flying and occurs due to various atmospheric factors. Airlines prioritize the safety and comfort of their passengers and have robust systems in place to handle turbulence.

So the next time you encounter turbulence during your flight, rest assured that it is a temporary and manageable situation.

When to Expect Turbulence

Understanding when to expect turbulence can help alleviate anxiety and provide a more comfortable flight experience. Turbulence can occur at various stages of a flight, including takeoff, landing, cruising altitude, during thunderstorms, and due to mountain waves.

Let’s take a closer look at each of these situations:

Takeoff and Landing

During takeoff and landing, aircraft can encounter turbulence due to factors such as crosswinds, jet engine exhaust, or air movement caused by nearby buildings or terrain. These factors can create brief periods of moderate turbulence that usually last for a few minutes.

Pilots are trained to anticipate and handle such conditions, ensuring the safety of the passengers and crew.

Cruising Altitude

While cruising at altitude, turbulence can occur due to changes in wind speed or direction. Jet streams, which are high-speed air currents in the atmosphere, can sometimes cause pockets of turbulence. However, modern aircraft and advanced weather forecasting systems allow pilots to navigate around these areas of turbulence, minimizing any discomfort for passengers.

It’s worth noting that turbulence encountered at cruising altitude is usually mild and short-lived.


Thunderstorms are known for their turbulent conditions. The updrafts and downdrafts associated with these storms can create significant turbulence. Pilots and air traffic controllers closely monitor weather patterns to avoid flying through thunderstorms whenever possible.

In cases where storms are unavoidable, pilots will navigate around the most intense areas of turbulence, prioritizing passenger safety.

Mountain Waves

When air encounters a mountain range, it can create what is known as mountain waves. These waves occur on the lee side of the mountains and can cause turbulence as the air flows over the peaks and down into the valleys.

The severity and duration of mountain wave turbulence can vary depending on factors such as wind speed and the shape of the terrain. Pilots are trained to recognize and anticipate mountain wave turbulence, adjusting their flight path accordingly.

Remember, turbulence is a normal part of flying and is generally nothing to be concerned about. Pilots are experienced in handling these conditions and prioritize passenger safety above all else. So sit back, relax, and enjoy your flight!
