A fair weather friend is well a friend that you may think is a good friend but then as soon as your life is going as bad and you need a good friend for help and support he ditches and leaves you. If not forever at least until the "weather" is going good again.
Example:
I thought John would always stick beside me but when I was in trouble and needed help it turned out that he only a fair weather friend.
Someone who claims to be a friend when one's fortunes are on the rise but who is conspicuously absent in times of trouble.
There are lyrics about fairweather. You can also be a fair weather friend, who is only a friend when things are going good. There are videos you can watch about fair weather. Also, that means when the weather outside is fair, not hot, clod, raining, snowy, etc.
