No matter the temperature scale, during the daytime, the land temperature may increase by tens of degrees, while water temperature increases slightly or let say just less than half a degree. So, the air moves from the high-pressure area formed over the landmass towards the ocean. During that time, the high pressure prevails over the landmass. After the sunset, the temperature over the landmass cools quickly in comparison to the ocean. In warm tropical areas, where there is a continuous intense solar heating (insulation)throughout the year, people leaving there experience stronger and regular breezes compared to higher latitudes. Over the lakes, the height of circulation is less but can extend inland up to 100 mi (161 km) or manifest as local phenomena that quickly weaken with a few hundred yards of the shoreline. The land and sea breezes systems are very shallow with an average depth of 1-2 km. There is a complete reversal of wind direction of these coastal winds. Land and sea breezes are types of local winds that occur daily on the sea coasts due to differences in the surface temperature of the sea and adjacent land. Night minimum temperature is higher when the north-westerly wind persists throughout the night.However, under these conditions, the land breeze will be weaker, start later and may not occur at all. The sea breeze is strengthened by a northerly flow such as when there is a surface low-pressure cell to the east, or an anticyclone approaching from the west and it starts earlier.However, a sea breeze is weaker and start later, or may not take place at all. The land breeze is usually strengthened by the southerly flow which flows ahead of a surface low-pressure cell to the west.Land and Sea breezes take place due to the contrast between land and sea surface Temperature.Sea breeze normally starts in the morning, a few hours after sunrise, when the solar radiation heats the boundary layer over land.Land breeze takes place at land in the night when the land has become cooler.
