Glasgow upper vs London lower
Glasgow. Visit May through September for the best chance of dry, mild days and long Scottish daylight — late May to mid-June is the sweet spot. Skip November through February unless you specifically want cosy indoor culture: 7-hour days, near-constant cloud, and 240+ hours of rain a month.
