Domain knowledge for UKHO Tidal API — workflow patterns, data models, and gotchas for your AI agent.

UKHO Tidal API

The ADMIRALTY UK Tidal API provides authoritative tidal height predictions for Standard and Secondary tidal level stations around the United Kingdom.

Data Model

  • Stations — 607 tidal stations around the UK with metadata (name, country, coordinates, type).
  • Tidal Events — High Water (HW) and Low Water (LW) events with predicted times and heights.
  • Continuous — Foundation/Premium tiers offer continuous height predictions (not in Discovery).

Key Patterns

  • Station IDs are alphanumeric strings (e.g. '0001', '0113').
  • Discovery tier gives current + 6 days of HW/LW events.
  • All times are in GMT (Greenwich Mean Time) — BST is never applied.
  • Coordinates follow geoJSON convention: longitude first, then latitude.
  • Some stations only have High Water data (e.g. Rye Harbour dries out at low water).
  • Some south coast stations may show 4 high waters per day due to double-HW effects.

Gotchas

  • No caching on Discovery: Discovery tier terms prohibit storing/caching data.
  • GMT only: All predicted times are GMT. Consumers must handle BST conversion.
  • Channel Islands excluded: Tidal data for Channel Island stations is not available.
