Everything You Need to Know About Sea Conditions in the Southern Atlantic Ocean (South Africa)

The Southern Atlantic Ocean (South Africa) region has a subtropical climate with temperatures driven by the sea temperatures which are strongly influenced by two main currents, Agulhas to the east/south and Benguela to the west. Those currents are result of the interaction between three oceans; the warm Indian Ocean, deep cold waters from the Southern Ocean or also called Antarctic Ocean and finally the South Atlantic Ocean.


Therefore, the area has sort of three different climates which from the west to the east change from mild and drier to warmer and rainier.


Why is the region essential for the offshore industry?


Southern Africa is a very strategic area for the maritime industry. Several important ports are located on the Southern Africa region and most of them are important for shipping routes regarding bunkering, sheltering, maintenance and are hubs for import/export at one of the richest economies in Africa.


Why is it vital to understand sea conditions?


Accurate and precise weather forecasts are a necessity in most offshore operations to reduce costs, mitigate or avoid delays and improve safety.


When operational limits are marginal, understanding the sea conditions through accurate forecasts are essential (and often required by insurers). Short to medium term forecasts (5-7 days) help with day to day running, ensuring operational limits and the safety of personnel/equipment are within bounds. Further Outlook Forecasts (15 days) give project managers, stakeholders, and decision-makers a better idea of upcoming weather events and help them mitigate potential delays.
