Possible Impacts
No major marine impacts are forecast over the next seven days. However, mariners should exercise caution during periods of heavy showers or thunderstorms, as seas may become locally rough or choppy in their vicinity, particularly due to gusty winds.
Spring Tides, which are higher-than-usual high tides and lower-than-usual low tides, are forecast to end on July 24th. All marine interests are advised to exercise caution, particularly during high tide periods.
Lastly, Saharan Dust levels are forecast to increase from July 20th, leading to increasingly hazy skies and marginally decreased horizontal visibility, particularly near dust and dawn.
Rip currents always pose a hazard on the nation’s beaches. If caught in a rip current, swim perpendicular to the current (parallel to the shore). Mariners, especially small craft operators, should ensure their vessels are securely anchored or docked, as choppy/breaking wave conditions may drag the vessel onto the ocean floor or reefs in shallow waters or even break anchorage/mooring.
