- Stability Characteristics
- High consistency, minimal impact from westerlies

This ranking is based on global offshore wind energy assessment data as of 2026, evaluating marine areas based on wind speed stability, annual capacity factor consistency, and low impact from extreme weather events. It provides essential scientific guidance for site selection in offshore wind energy development.

In offshore wind, volatility is the primary adversary for turbine fatigue and grid integration. While the North Sea boasts high wind speeds, it faces seasonal storm disruptions. Conversely, regions in the Southern Ocean and specific straits demonstrate superior consistency due to persistent westerly winds. Note: Data provided by the IEA and Global Meteorological Satellite Monitoring Center, with sudden typhoon impacts excluded.
