Peak District in February

May through September gives you the most reliable weather and longest days, but also the biggest crowds. July and August see the heather bloom on the moors, turning the Dark Peak purple, but expect packed car parks and booked-up accommodations. September might be the sweet spot — still warm enough for comfortable hiking, fewer families, and autumn colors starting to show. Winter brings its own stark beauty, especially after snowfall on the gritstone edges, but many attractions close and daylight hours shrink dramatically. Spring arrives late here, with lambing season in April providing entertainment but also temporary footpath closures. The weather changes quickly at elevation, so pack layers regardless of season. Rain gear isn't optional — this is northern England, after all.
