Understanding marine and ocean weather

For many Australians, sea and surf is part of our lifestyle. About 85% of us live within 50 km of the sea. We head to the coast for work and recreation, and many industries rely on the ocean.

Most of Earth's surface is covered by oceans. These vast bodies of water are critical to sustaining life on our planet. Their complex relationship with the atmosphere helps to drive our climate and weather.

At the Bureau, we measure and model marine, coastal and ocean processes. This vital work underpins the forecasts and warnings that help keep Australians safe at the shore and on the water. Our work contributes to global understanding of our oceans and climate.
