A friend who is only a friend when circumstances are pleasant or profitable. At the first sign of trouble, these capricious, disloyal friends will drop their relationship with you.
I had thought Ted would stand by me when I was accused of theft, but it turned out he was only a fair-weather friend.

A friend who is only nice to you when it's convenient. Someone who's wishy-washy. Someone who is a "backstabber." Someone who abandons you in certain situations.

A friend who doesn't help in times of difficulty. Likely nautical in nature, referring to the fact that when weather is good nearly anyone can help on a ship.
