The Quiz: What is the Beaufort scale used for in San Francisco Bay?
A Testing salinity of the ponds
B Weighing salt
C Measuring maritime wind
Away from the salt evaporation ponds, boating is a popular pastime in San Francisco Bay. But the winds across the bay can get strong. So, while the bay keeps your sailboat safe from large ocean waves, a Beaufort force 6 wind (25–31 mph) can kick up quickly.
The correct answer to this quiz is Measuring maritime wind.
