Our take: August in Guanajuato is ideal if you love mild weather and don't mind afternoon showers. Expect pleasant 14–25°C temperatures with about 12 hours of daily sunshine, though rain hits roughly half the days—perfect for exploring colonial architecture in the morning, then relaxing at a café while the sky clears. Pack layers and a light rain jacket; this is a traveler's month, not a sunbather's.
