What San Jose's weather means for gyms
Summer here stays moderate, with an average August high of 81°F and only about 16 days a year at 90°F or more, so a tri-blend tee works for training and the walk home in most months. Winter is gentle, with December still averaging a high of 60°F, so a light hoodie or quarter-zip covers the cool months and a heavyweight hoodie is rarely needed. Between the tank months and the hoodie months, a long-sleeve tee or quarter-zip sells best, so keep one in the core range all year. At about 13 inches of rain a year, a park workout or outdoor bootcamp is rarely rained out, and a cap earns a place on the rack.
