Short answer: summer to swim, winter for sunrise and seaside walks
In both Gangneung and Sokcho, swimming is allowed only during each beach's official summer season. If you want to get in the water, go in summer. Dates change every year, so check the Gangneung and Sokcho city tourism sites.
For sunrise and seaside walks, winter works well too. December-February rainfall is about 36.9 mm, about 47.9 mm and about 48 mm in Gangneung and about 40.1 mm, about 43.5 mm and about 45.9 mm in Sokcho, far less than July-August (Gangneung about 250.2 mm and about 292.9 mm, Sokcho about 265.6 mm and about 298 mm). But average lows in both cities are below zero in December-February.

The winter sea: sunrise and snow
Jeongdongjin in Gangneung is a famous New Year sunrise spot. Jeongdongjin Station is in the Guinness book as the train station closest to the sea in the world, and the beach is about a 3-minute walk away. It is about 14 minutes from Gangneung Station by KTX-Eum, but there are few trains, so check times.
In Sokcho, Yeonggeumjeong is a popular spot for sunrise and sunset, and the Daepo Port Observatory on the hill behind Daepo Port is a sunrise spot too. Seoraksan has winter snow scenery. The Seorak Cable Car may stop in strong wind or bad weather, and some trails close during restricted-entry periods, so check the Korea National Park Service site (knps.or.kr).
In Gangneung accommodation is most of the budget, so for sunrise dates compare prices for your dates on booking sites early. The Sokcho gaetbae ferry runs 05:30–22:30 from November to April (may change with the weather).
- January: Gangneung high about 5.3°C / low about -2.7°C / about 47.9 mm · Sokcho high about 4.2°C / low about -3.8°C / about 43.5 mm
- Jeongdongjin: New Year sunrise spot, beach about 3 minutes' walk from the station

The summer sea: swim only during the official season
Gangneung's Gyeongpo Beach is called the largest beach on the east coast, with 1.8 km of white sand backed by 4 km of pine forest, and showers (KRW 3,500) in swimming season. Climb Gyeongpodae Pavilion, 1 km from the beach, to see Gyeongpo Lake and the sea together. Sokcho Beach is a 5-minute walk from the Express Bus Terminal, and its sand stretches 940 m.
Swimming is allowed only during each beach's official season. There are no lifeguards before the season opens or at night, so you can't go in the water then. Season dates change every year, so check official information.
In Sokcho, mulhoe, made from fresh live fish and served with ice, is a summer favourite. For the summer holidays, compare hotel prices for your dates early in both cities, and book KTX-Eum Donghae Line tickets ahead on Korail Talk, as they sell out fast in the summer holidays.
- August: Gangneung high about 28.6°C / low about 21.9°C / about 292.9 mm · Sokcho high about 27.5°C / low about 21.2°C / about 298 mm

- Sokcho Beach: 5-minute walk from the Express Bus Terminal, 940 m of sand
