The Met Office says that currently, sea conditions are moderate occasionally rough with wave heights reaching 2.5 metres and occasionally 3.0m in open waters, and near 1.0m in sheltered areas.
It says that similar conditions will continue for the next 24 to 48 hours as a result of relatively strong surface winds.
However, over the weekend, sea conditions will gradually deteriorate and become more agitated as surface winds are forecast to strengthen further.
Marine conditions from Saturday 10th February 2018 are expected to become more disturbed with wave heights in open waters reaching 3.0m and above especially along north and east coasts.
In sheltered areas, choppy seas may be experienced.
These adverse sea conditions over the weekend are forecast to persist into next week.
Small craft operators, sea bathers and all other marine interests are asked to exercise caution in any sea related activities.
The Met Office says it is closely monitoring sea conditions and will issue an update at 12:00 p.m. tomorrow, Thursday 8th February 2018, or earlier if the situation warrants.
