The Met Office is maintaining the rough seas bulletin with a Yellow Level alert.
The Met Office says that long-period north-easterly swells generated by Hurricane Lorenzo continue to affect northern and sheltered nearshore coastal areas.
It says the effects will be in the form of occasional battering waves which can lead to localised disruption to sea bathing and other nearshore coastal activities.
Localised beach erosion is also possible.
The Met Office says the effects will be exacerbated at high tide, as spring tides are in effect.
It is advising sea bathers, fishermen, and small craft operators to carefully monitor nearshore coastal sea conditions and exercise caution along affected areas.
“Be alert for dangerous breaking waves and currents. Follow the instructions of lifeguards,” the bulletin said.
