In Delaware, spring (March to May) brings temperate weather with blossoming flora, making it an appealing time for hikers. However, trails can be muddy from rain, suggesting waterproof gear may be beneficial.
Summers (June to August) are hot and humid, best suited for coastal or forest hikes, which offer some respite from the heat. It's essential to stay hydrated and avoid midday hikes.
Autumn (September to November) is arguably the best hiking season in Delaware, with mild temperatures and stunning fall foliage. Winter (December to February) can be cold, but clear days can offer serene hikes, albeit with proper cold-weather gear. For more information, consult the Delaware State Parks website
