Scoring methodology (for technical users)
We score each hour from 0 to 1 using daylight and these weighted components:
- Wave height (35%): best below 0.36m, then decreases as it rises.
- Wind speed (25%): best below 5.4m/s, lower is better.
- Sea surface temperature (15%): best within 20.6°C to 30.4°C.
- Tide and currents (15%): best around slack/high-tide windows.
- Daylight (10%): visibility is better in daylight, so night hours score lower.
