How the sea behaved, and whether you can go out this week.
For every farm we collect a year of hourly waves, currents and tides plus a 7-day forecast. They drive the scour and cable models, and also give storm alerts and survey-vessel windows.

Now, the past year, the next 7 days.
In the Southwest Sea demo the annual 95th percentile was 1.44 m significant wave height and 0.83 m/s current (14 Nov 2025 – 13 Nov 2026), which set the storm alert level.
- Current Hs and period, depth-averaged current, tide level
- Annual 95th percentile Hs and current (storm alert level)
- Daily max wave and current for a year; daily tidal range
- 7-day forecast: Hs, period and current per day
Weather windows
Plan the survey vessel 7 days ahead.
Days when the daily maximum significant wave height stays at or below the vessel limit (1.5 m by default) are marked Go. Read them with the risk ranking and the survey schedule falls into place.

Specification
Data
| Data | Use | Resolution · cadence |
|---|---|---|
| Open-Meteo Marine | Significant wave height, period, direction, currents, tide for one year + 7-day forecast | about 5–8 km · hourly |
| GMRT (GEBCO + multibeam) | Water depth per foundation and cable segment | about 100–450 m |
Can we use our own metocean data?
Yes. If you have site wave and current measurements or model results, we agree how to use them.
Can the 1.5 m limit be changed?
The default is a daily max Hs of 1.5 m. The right limit for your vessel and task is agreed during the pilot analysis.
