Over the next seven days, moderate seas are forecast as winds vary between moderate to strong across the region. In heavy showers and thunderstorms, seas can become locally choppy in sheltered areas and rough in open waters. Spring tides are also forecast through next Thursday, with occasional long-period swells requiring caution from all near-shore marine interests.

Possible Impacts
Saharan Dust concentrations are forecast to be present during the forecast period but are not expected to affect visibility significantly.
Occasional long-period swells from the north, combined with spring tides ongoing through November 16th, 2023, will require additional caution from beachgoers and marine interests, particularly during high tide periods due to increased risks of rip currents and larger near-shore waves.
Spring tides are larger tidal ranges due to, in this case, the new moon, so coastlines observer higher than usual high tides and lower than usual low tides. Long-period swells produce high-energy waves near coastlines, resulting in larger, battering waves that can cause minor coastal flooding, beach erosion, and potentially hazardous beach and marine conditions.
