From Glossary of Meteorology


(Often contracted sou'easter.) A southeasterly wind, particularly a strong wind or gale, for example, the winter southeast storms of the Bay of San Francisco.

A specific application to a local wind is the southeaster of Table Bay, South Africa (Table Mountain southeaster). When there are dark clouds over Table Mountain, it is a black southeaster; when there are no clouds, it is a blind southeaster.
