🔍 Key Concepts

• Wind-driven vs. swell-driven seas • Relationship between local wind direction and wave direction • How cloud movement can indicate wind aloft

💭 Think About

• Which of these surface conditions is created directly and immediately by the local wind acting on the water? • Which option can persist and travel long distances even after the local wind changes? • Which of these indicators best shows the current surface wind direction where your vessel is, not past or distant weather?

✅ Before You Answer

• Identify which sea conditions are locally generated by present wind versus those that can be generated far away. • Ask: Does this feature (clouds, swells, whitecaps, waves) always line up with the current surface wind at my location? • Eliminate the option that may not correspond to the present local wind direction, even though it is related to weather at sea.
