How to Use Tidal Data for Planning with ChatGPT
Use tidal statistics for coastal planning with ChatGPT and ToolRouter. Tide times and conditions for any location.
Tool
ChatGPT presents tidal statistics in practical planning formats — tide tables for the day, recommended activity windows, and written summaries that are easy to share with a group. It is well suited to building trip itineraries that work around the tide rather than against it.

Steps
Once connected (see setup above), use the Ocean & Tides tool:
- Ask: "Get tidal statistics for St Michael's Mount, Cornwall for this weekend using ocean-data"
- ChatGPT returns high and low water times and levels for each day
- Request: "Write a day trip itinerary that fits around the tidal windows"
- Follow up: "What time should we leave to guarantee crossing on foot?"
Example Prompt
Try this with ChatGPT using the Ocean & Tides tool
Get tidal statistics for St Michael's Mount for Saturday and Sunday. Write a day trip plan for each day that works around the tidal causeway access windows.
Tips
- Ask for crossing windows rather than just tide times — factor in the walk time too
- Request a printed tide table format if you'll be without internet on the day
- Plan around springs tides (biggest range) for the most dramatic low-water exposures
