Tidetech is pleased to release its high-resolution Whitsunday Islands hydrodynamic tidal current model for the 2026 Airlie Beach and Hamilton Island Race Weeks.
The Whitsundays are renowned for spectacular sailing and notoriously complex tidal flows. Whether you’re a regular competitor or arriving for the first time, access to reliable tidal current data can make a significant difference when it comes to tactical and strategic decision-making.
Our scientifically validated finite element hydrodynamic model helps remove uncertainty from race planning, giving crews access to detailed local tidal intelligence throughout the regatta.

What makes the model different?
- High-resolution tidal current data at approximately 200-metre resolution
- Detailed coverage capable of highlighting important local features, including current accelerations and back eddies around headlands
- A 30-minute time step, allowing users to track changes in current strength and direction throughout the tidal cycle
- Fully scientifically validated hydrodynamic modelling
- Available exclusively in GRIB file format (for use in navigation software like Expedition, Adrena, and Time Zero)
Designed for race-winning decisions
Every race week campaign relies on making hundreds of small decisions. Understanding where the tide is helping, hindering or changing direction provides valuable insight when selecting routes, managing mark roundings and identifying opportunities across the course.
With the Tidetech Whitsundays model, you can access the same high-quality ocean intelligence used by sailors around the world and bring detailed local tidal knowledge onboard, wherever you’re competing from.

Pricing and access
The Whitsundays Race Week tidal model pack is available for AU$199 and covers either your Airlie Beach Race Week or Hamilton Island Race Week campaign.
Once registered, you’ll receive a link providing access to download the GRIB files.
