The Port Authority of NSW survey team calibrates and maintains tide gauges, anemometers, current meters, and wave-measuring buoys across all major NSW ports.
Shipping operators and meteorologists use data from these sensors daily for navigation and real-time weather-related decisions. The Port Authority sends all tide data to the Bureau of Meteorology, which uses it to generate tide prediction charts.
For tide predictions and tide tables, visit the Bureau of Meteorology.
