7/2-7/4: Semana Nautica Summer Sports Festival: “Nautical Week” is a tradition that began in 1933 when visiting Navy sailors engaged vigorous residents in fun and games on the waterfront. Most of the activities in the 79th edition of the festival are concentrated over the Fourth of July weekend. They include an age-group swim meet at Los Baños del Mar Pool; open beach volleyball tournaments at East Beach (men Saturday, women Sunday); ocean swims off East Beach (1-mile Saturday, 3-mile Sunday); and the 62nd Semana Nautica 15K Run on Monday. The 9.3-mile run will follow a new course that starts and finishes at Hollister Elementary School, with a turnaround at Goleta Beach. It’s all free to spectators. Visit semananautica.com.
