Why does the wind always flow from the ocean to land at a beach and never the other way round?
Land normally heats up faster than water. During the day, the air above the land also gets warmer and rises, causing a slight low pressure to develop above the land. The air above the sea doesn't warm up as much, so is at a slightly higher pressure.
The Short Answer
Land normally heats up faster than water. During the day, the air above the land also gets warmer and rises, causing a slight low pressure to develop above the land. The air above the sea doesn't warm up as much, so is at a slightly higher pressure. The onshore breeze is the air moving from (relatively) high pressure to low pressure. The reverse occurs at night when the land cools down faster than the sea. This only occurs when the overall weather is fairly calm. Storm systems easily overcome this effect.
