What we forecast
One model for every layer of moving water, from the surface skin to the seabed tide.
0 – 2 m
Surface currents
Wind-driven flow in the top two metres, where people, debris and oil actually go.
200 m grid · every 6 minFull depth
Tidal streams
Harmonic tides corrected every cycle against 140 live seabed current meters.
72 h horizonAnything afloat
Object drift
Leeway for 64 object classes, from a person in the water to a 40 ft container.

Accuracy
Checked against real drifters every month, and published.
1.9km median error
after 24 h of drift, across 1,140 released drifters in 2025.
Operations
Built for people who work on the water.
Offshore wind
Cable lay and jack-up windows
Know the hours current drops below your vessel's limit, three days out, per turbine.
Search & rescueWhere to search first
Drift cones for a person in the water, updated as the tide turns, in under 40 seconds.
Spill responseWhere the slick lands
Shoreline arrival times for oil and debris, so booms go down before it arrives.
Field report
“We used to add a day of weather margin to every cable pull. With Tidewell we plan around the actual slack water, and finished the export route eleven days early.”
