How this helps travel recommendations

Flags rain, heat, flood, tide, river, storm, and exposed-day risk before recommending beaches, roads, waterfalls, ferries, or mountain plans.

Developer reference

Best endpoint

Prefer official warning, forecast, observation, hydrology, tide, or climate endpoints over rendered forecast pages.

Recommended refresh

Check weekly for change detection, but treat the official publication period as the real cadence.

Travel scoring role

Flags rain, heat, flood, tide, river, storm, and exposed-day risk before recommending beaches, roads, waterfalls, ferries, or mountain plans.

Failure modes

  • Forecast and warning schemas can change.
  • Some sources publish reports rather than stable APIs.
  • Local conditions can differ sharply from provincial summaries.
  • Batch files can change schema, naming, encoding, or publication cadence.
