Local Winds: Sea Breezes
Although global winds are important in determining the prevailing winds in a given area, local climatic conditions may wield an influence on the most common wind directions.
Local winds are always superimposed upon the larger scale wind systems, i.e. the wind direction is influenced by the sum of global and local effects. When larger scale winds are light, local winds may dominate the wind patterns.
Sea Breezes
Sea breeze cartoon Land masses are heated by the sun more quickly than the sea in the daytime. The air rises, flows out to the sea, and creates a low pressure at ground level which attracts the cool air from the sea. This is called a sea breeze. At nightfall there is often a period of calm when land and sea temperatures are equal.
At night the wind blows in the opposite direction. The land breeze at night generally has lower wind speeds, because the temperature difference between land and sea is smaller at night.
The monsoon known from South-East Asia is in reality a large-scale form of the sea breeze and land breeze, varying in its direction between seasons, because land masses are heated or cooled more quickly than the sea.

Definitions of Local winds on the Web:
Winds which, over a small area, differ from those which would be appropriate to the general pressure distribution.
www.novalynx.com/glossary-l.html
Small-scale convective winds of local origin caused by temperature differences.
www.pfmt.org/fire/glossary.htm
Winds that are prevalent in particular areas at particular times and have special features. Usually they have special names. The Bora, the Pampero, the Mistral, the Levanter and the Sumatra are examples.

Local Winds
All winds, from gentle breezes to raging hurricanes, are caused by differences in the temperature of the atmosphere, by rotation of the Earth, and by unequal heating of the continents and the oceans.
