Global tidal data for maritime operations

Tidetech’s global tidal products provide consistent, operational‑grade tidal intelligence designed to support decisions where access, clearance and timing matter across the world’s maritime network.

This product family includes global tidal predictions, tide‑surge datasets and supporting services designed for large‑scale operational use.

  • Port access and departure planning
  • Under‑keel clearance assessment
  • Channel and shallow‑water transits
  • Schedule coordination around tidal windows
  • Voyage planning in tide‑affected regions
  • Regulatory and safety‑related decision support

These products are designed for integration into navigation systems, port tools and optimisation platforms — not standalone tide tables.

  • Global tidal predictions
  • Tide and storm‑surge datasets
  • Tidal height time‑series (gridded and point‑based)
  • Tidal services aligned with operational workflows

All datasets are either created, or curated from official sources, and validated in house, then delivered in formats optimised for maritime operations.

Tidetech’s global tidal height product provides continuous tidal height predictions computed on a 2km alongshore grid for every coastline on Earth — not interpolated from a sparse network of standard ports.​

The product is designed for large‑scale operational delivery and is used by major technology platforms, with millions of tidal height data points delivered every day into live, user‑facing applications, like wearable apps.

Global tidal heights help organisations to:

  • Provide reliable tidal height information along open coastlines
  • Reduce uncertainty introduced by coarse, station‑based interpolation
  • Support navigation, planning and situational awareness in coastal environments

The dataset is delivered as an operational product, built for integration into apps, digital services, navigation tools, compliance and decision‑support systems.

Designed for integration across maritime systems

Global tidal products are built for dependable, repeatable use in operational environments.

They integrate with:

  • ECDIS and onboard navigation systems
  • Port and terminal decision‑support tools
  • Shore‑side planning and fleet‑management platforms
  • OEM navigation and situational awareness systems

Delivery options include secure API access and gridded datasets in industry‑standard formats such as GRIB, NetCDF and S‑100‑aligned services (S-104 water levels), with flexible sub‑setting to match operational needs.

Tidetech metocean intelligence integrates with maritime systems for better decisions

Global tidal products are designed to deliver:

  • A view of tidal behaviour across regions
  • Tidal data from scientific models, not interpolated between observation points
  • Reliable planning in tide‑dominant environments

They complement regional high‑resolution tidal models, providing a dependable global foundation where local detail is not required or not yet available.

Scientific validation and reliability

Tidetech’s global tidal products are developed and maintained by oceanographers and specialist developers using validated tidal models, observational data and long‑standing domain expertise.

They are used operationally across the maritime sector and continuously validated against real‑world conditions.
