fair-weather

Lacking storm clouds

Fair-weather describes someone or something that is reliable only under favorable conditions.

A fair-weather friend is one who disappears when times get tough, sticking around only when things are going well.

The term extends to other nouns: fair-weather fans support their team only when it's winning.

The literal sense—suitable for or occurring during good weather—is less common but still used: fair-weather sailing conditions.
