Old Sky Rules

How it helps

Use it for a focused task

A practical reference for traditional weather lore organized by season and sky cue, with reliability notes, common mistakes, and a small trip planner that saves cues in your browser. Browse the seasonal tabs, filter cues by reliability, then save the ones that matter for an upcoming trip.

Use the planner to build a short list and share or print it. Phone forecasts fail when batteries die or signals drop.

Old sky rules give you a backup sense of what the weather may do next, using cues you can see, feel, or smell. Lore is not a replacement for official forecasts during severe weather.
