Difference between Land Breeze and Sea Breeze

Have you tried walking barefoot on sand during noon? You can barely touch the sand because it is scorching hot. When such a thing happens, you may need to dip your feet in a lake nearby. 

Although the sun warms up both water and sand, the pace at which water absorbs heat is not the same as sand. This difference in heating is the basis for the formation of land and sea breeze.

What is Sea Breeze?

Before learning about the difference between land breeze and sea breeze, let us learn a bit more about what a sea breeze is. 

Sea breeze blows during the day. The sun heats up both the land and sea at this time. However, the land heats up sooner, which causes the air over land to become hot faster than its counterpart above the sea. This hot air expands and rises, causing a low-pressure system.

At the same time, air over the sea remains cooler since water can retain its temperature more than the land. This cooler air is heavy and quickly flows toward the low-pressure region on land. This flow of cooler air from sea to land during the day is known as a sea breeze.

What is Land Breeze?

A land breeze blows during the night. The process explained above is reversed when night falls. Land heats up quickly but also cools quickly. Thus, after the sun sets, sea air remains hotter for a longer duration. This leads to low-pressure creation over this sea. Land air being cooler, it quickly flows to replace the lighter air over the sea.       

After understanding the basics, one can quickly assess the difference between land breeze and sea breeze. Read on to help you with this distinction.

Difference between Land and Sea Breeze

Several factors distinguish between land breeze and sea breeze. Assess the table below for further knowledge regarding this difference.

Sea Breeze

Land Breeze

Sea breeze tends to be deep.

A land breeze is comparatively shallower when compared to a sea breeze. 

Sea breeze reduces the temperature.

Land breeze generally has no effect on temperature.

A sea breeze is more prevalent during the summer and spring seasons. This happens because temperatures remain higher during the day in these seasons. 

A land breeze is more common during winters and autumns. The nights tend to stay cooler at such times.

Sea breeze tends to be faster, flowing at speeds of up to 20 knots.

Land breeze flows much slower, with top speeds ranging up to 8 knots.

Sea breeze carries increased moisture, which it absorbs while blowing over a water body.

Land breeze is drier since it has no opportunity to absorb water from any source.

Lastly, the sea breeze moves from the sea towards a land body.

Land breeze moves from land toward a water body, generally a sea or ocean.

Quick Question –

Q. Why do land and sea breeze occur?

Ans. Land and sea breeze occur due to the difference in the heat absorption and retention capacity of land and water. If water and land retained heat at the same pace, such winds would not occur. 

Temperature Difference Inland and Near the Sea

Now that you can differentiate between land and sea breeze, you can also understand why locations near seas tend to experience limited temperature variance throughout the year. This means that such locations usually witness constant temperature. In case of inland locations, the temperature difference is more prominent.

During the day, temperatures soar in such inland areas. However, as night falls, these places tend to experience cooler weather. 

Interesting Note

You can perceive clouds from a coastal area at night, which dissipates in the morning. This happens due to this flow of breeze.

FAQ (Frequently Asked Questions)

1. How does land and sea breeze occur?

Land breeze occurs at night when a low-pressure system forms over the sea. During the day, low-pressure formation occurs over the land, thereby allowing wind from sea to fill in this deficit.

2. What is the maximum speed for sea breeze?

A sea breeze is faster than its land counterpart, with top speeds of up to 20 knots.

3. What is the difference between land breeze and sea breeze?

Land breeze and sea breeze differs on many accounts, including depth, speed, moisture, direction, strength, etc.
