Louisville in April

April through May is peak Louisville. The weather's perfect, Derby season brings energy to the whole city, and everything's blooming. But expect crowds and higher prices during Derby Week in early May. Fall is equally gorgeous—September through November gives you comfortable temps and beautiful foliage. October is ideal for bourbon trail drives when the leaves are changing. Plus, fewer tourists mean better restaurant reservations. Summer gets hot and humid, typical for the South. But that's when the outdoor concerts happen at Waterfront Park and the beer gardens are in full swing. Winter is mild compared to northern cities, though January and February can be gray and dreary.
