Port Nolloth Beach faces typical west coast Atlantic conditions with cold water temperatures year-round and occasional strong currents. While the harbour area provides some shelter, swimming requires caution. There are no lifeguards, so swimmers should stay close to shore and never swim alone. The beach is more popular for walks and fishing than swimming. Children should be closely supervised near the water. The urban setting means facilities like toilets and parking are available, but always assess conditions before entering the water.

Port Nolloth Beach is best visited during South African summer and spring (September to March) for the warmest weather, though temperatures remain relatively mild year-round on this coast. Budget travellers benefit from visiting during off-peak months when accommodation rates are lower. The town experiences less extreme temperature variations than inland areas. Mornings tend to be calmer, while afternoons can bring wind. Sunset viewing is spectacular throughout the year. For wildflower enthusiasts, August to September offers nearby Namaqualand blooms.
