Gravity is strongest between an object and the Earth at the object's surface. In your seaside community context, whether the object is on the ground, in the water, or at a higher elevation (such as a building or cliff), the gravitational pull remains relatively strong as it is directly influenced by the mass of the Earth and the distance from its center.
The gravitational force decreases with distance, so the closer the object is to the center of the Earth, the stronger the gravitational attraction will be. Thus, gravity will generally be strongest when the object is on solid ground (land or seabed) compared to being in the air or at a significant height above the ground.
If there are variations in elevation (like a hill or cliff), gravity will be slightly weaker the higher you go above sea level, but such differences are usually minimal and might not be significant for practical purposes in everyday scenarios.
