The city's beach is popular for sunbathing, beach volleyball, surfing, paddleboarding, bars, cycling and running. The city itself extends only about 15 blocks from east to west and 40 blocks from north to south, with Pacific Coast Highway running down the middle. Situated on the Pacific Ocean, Hermosa's average temperature is 70 °F (22 °C) in the summer and 55 °F (13 °C) in the winter. Westerly sea breezes lessen what can be high summertime temperatures in Los Angeles and elsewhere in the county and help keep the smog away 360 days of the year.
