What Indianapolis's weather means for gyms
Indianapolis has 3 months with average highs under 45°F (December to February), so members walk in bundled up and a gym hoodie or crewneck gets worn there and back. July highs average 85°F, warm enough that May to September is a true tank season and a good time for an outdoor summer challenge shirt. Between seasons, a long-sleeve tee or quarter-zip covers cool spring and fall mornings, when members want a layer but not a full hoodie. About 26 inches of snow fall in a typical year, enough to move outdoor sessions inside for stretches of winter and make a long-sleeve challenge shirt worth planning. The thermometer falls to freezing or below on about 106 nights a year, so a cuffed beanie with the gym logo sells steadily at the front desk for months.
