The Stellenbosch office of the CSIR
continuously monitors real time ocean waves and weather
at various sites around the South African coast on behalf
Most of the data is gathered by means of
moored wave buoys. The measured data is transmitted
to a shore station where a comprehensive analysis is done.
The analysed data is then downloaded in near real-time to
Stellenbosch, where it is stored in a database.
In order to facilitate the need for
waves information where it is unsafe to deploy wave buoys,
the CSIR has implemented a 'Virtual Buoy System', whereby the
wave parameters are computed with the use of a numerical
waves and weather data is updated hourly, on the hour.
