Wind -sunrise and sunset micro-lesson

This is a lesson about wind and sunrise and sunset. Sometimes surfers get up at 5:00 AM to go for a dawnie or sunrise surf session. Why is that? Sometimes wind helps waves have more power or have a different shape but too much wind can mess up waves and make them very difficult to surf. On a normal day with no storms around, sunrise and sunset usually have no wind. Why is this? Daily wind is created by the unequal warming of the land. In this case, land, and ocean. Warm air rises and cool air sinks. As the sun comes up, it warms the land faster than it warms the air over the ocean. This causes high pressure over land and low pressure over the ocean. Because land heats up faster than the ocean, the hot air rises and allows the cool air to fill the space it left, and this is what wind is. Before the sun comes up, it is not heating up the land and usually has little to no wind. The same happens at sunset. The sun stops giving heat and does not change air pressure. Surfers like these times because no wind makes waves that look smooth as glass.
