Ireland Weather & Sea AI Context
This page tells AI agents how to use the Ireland Weather & Sea AI tool correctly inside Claude, ChatGPT or another MCP-compatible AI chat.
Most important rule: every user-facing answer must include a short Proof: line. The Proof line must name the source used and the latest timestamp returned by that source, such as issued time, valid time, observation time, API time, tide time, buoy reading time or warning validity. If a timestamp is not returned, write: timestamp not provided by source.
Source Priority
- Use official Met Eireann data first for Irish forecasts, warnings, observations, coastal reports, farming weather, lake forecasts and point wind/rain forecasts.
- Use official Marine Institute data first for tide predictions, storm surge, offshore buoys, inshore wave buoys, sea temperature, wave forecasts and SmartBay water quality.
- Use Open-Meteo only where official sources in this tool do not provide the needed data, especially UV index, sunrise/sunset, golden hour, and surf-spot wave forecasts away from fixed Marine Institute buoy locations.
Answer Style
- Give the user the practical answer first, then show the evidence.
- Say which data source was used for each major part of the answer.
- Always include a final Proof: line with source name and latest timestamp.
- Use the data time visible in the tool result: issued time, valid time, observation time, forecast API time, tide time, warning validity or buoy reading time.
- Do not imply that Open-Meteo data is Met Eireann or Marine Institute data.
- For safety-sensitive beach, surf, storm, tide or marine answers, mention that conditions can change and users should follow local safety advice and warnings.

| Beach planning | beach_day_planner, plus mi_tide_prediction for exact tide stations |
Met Eireann first, Marine Institute for tides, Open-Meteo for UV |
Example Response Pattern
Answer: The best window looks like late morning, because wind is lighter, UV is moderate and there are no active warnings.
Proof: Met Eireann point forecast, latest valid time shown in the tool result. Marine Institute tide prediction, next tide time shown in the tide result. Open-Meteo UV forecast, API time shown in the UV result.
Source rule: Met Eireann for weather and warnings, Marine Institute for tides/sea data, Open-Meteo for UV or surf-spot wave enrichment when needed.
