Pull down your hat on the wind side.

The saying can be direct practical advice: when wind can catch or chill you, secure the side most exposed rather than waiting for discomfort or loss. In context, its image may also support a broader caution.

Figuratively, it recommends anticipating trouble from its likely direction and taking modest precautions early. The emphasis is on alertness and self-protection, not on eliminating every risk or confronting danger directly.

Use it in a cautionary, proverbial tone to advise preparing for an obvious pressure point. Depending on context, it may be understood literally as advice about wind or figuratively as advice about likely difficulty.
