Offshore winds can easily cause seawater to move away from the coast, causing seawater to flow out of the waters it passes through, and deep water to recharge. This prevents the warm and moist airflow from the ocean from penetrating into the land, thereby dehumidifying the coast. Onshore winds are created when air blows from the sea to the shore, which is caused by heavier cold air at sea pushing lighter hot air over land. As the land temperature rises in the afternoon, the onshore wind will become significantly stronger. During the day, the sea breeze formed due to the difference in heating of the sea and land surfaces, and the wind blowing from the surface of large lakes, reservoirs and other water areas to the land surface, are all shoreward winds. In the trade wind belt on the east coast of low-latitude continents and in the westerly belt on the west coast of mid- and high-latitude continents, the wind blowing from the sea to the land is also considered a shoreward wind.
