Papua New Guinea National Tide Tables (PNGNTT) contains information for 21 Primary (Standard) and 152 Secondary ports in Papua New Guinea. This information includes:
- Predictions for high and low water for each day of the year for all Standard Ports.
- Tidal level and time differences for all Secondary Ports.
- Instructions and forms for calculating intermediate times and heights.
- Effects of wind and barometric pressure on tide, particularly at certain ports.
Updates to the PNGNTT are published via Australian Notices to Mariners.
Web Service
The PNGNTT tidal information is also available as an interactive web service. This platform provides an enhanced user experience, giving access to tidal information in an intuitive and functional way. It utilises a searchable map allowing specific port discovery with the ability to view and download individual port tidal data.
