What weather would create the weakest surfing waves

a. strong winds that blow for a short period of time with a short fetch.
b. weak winds that blow for long periods of time with a long fetch
c. strong winds that have been blowing for a long time with a long fetch
d. weak winds that blow for short periods of time with a short fetch

Answer is: D. Weak winds that blow for short periods of time with a short fetch.

Few factors determinate size of surfing waves:

1) Wind speed: the greater the wind speed the larger the wave.

2) Wind Duration: the longer the wind blows the larger the wave.

3) Fetch: the greater the area the wind affects the larger the wave.

So, strong winds that have been blowing for a long time with a long fetch will form biggest surfing waves.
