Smoke plumes are patchy and move with changing winds, terrain and weather. Nearby lakefront, coastal and higher-elevation places can be much clearer than San Francisco, but no direction is reliably cleaner. That is why this list is recalculated from live PM2.5 readings every hour instead of publishing a fixed escape route. If everything within three hours is smoky, the rankings will say so. Sometimes the honest answer is to stay inside with a filter running.
