The South African Weather Service (SAWS) has issued a warning for rough sea conditions along the Cape coastline this weekend due to an upcoming Spring tide, expected to peak on Thursday, 23 May 2024.
Spring tide expected to bring rough conditions along Cape coastline this weekend
The National Sea Rescue Institute (NSRI) has alerted boaters, sailors, paddlers, bathers, anglers, and coastal hikers to be cautious as the Spring tide will bring higher-than-normal high tides and lower-than-normal low tides, creating hazardous conditions.
SAWS forecasts indicate that the combination of the Spring tide and rough seas will particularly affect the West Coast, Western Cape, and South Cape coastlines.
NSRI spokesperson Craig Lambinon warned that the Spring tide could cause stronger than normal rip currents, and areas typically unaffected by high tides may be submerged by waves.
“Caution is advised and we appeal to public members and the maritime community to have safety top of mind,” Lambinon said.
Safety tips to avoid danger
To ensure safety during the Spring tide, the NSRI and other authorities have provided the following tips:
- Boaters, Sailors, and Paddlers: Always wear life jackets while your craft is underway, especially during rough sea conditions. Ensure that all safety equipment is easily accessible.
- Anglers: Be aware of high tide times and avoid fishing from areas that may become isolated or submerged during high tides. Do not cross to coastal islands during low tide as these could be cut off during high tide.
- Coastal Hikers: Avoid crossing river mouths and hiking trails close to the shoreline during high tide. The Spring tide can make these areas particularly dangerous with stronger currents and rising water levels.
- Bathers and Swimmers: Stay away from the shoreline during high tide periods and be cautious of rip currents that are stronger than usual.
What is a Spring tide?
A Spring tide occurs when the Earth, Moon, and Sun align, causing the gravitational forces to combine and produce higher-than-normal high tides and lower-than-normal low tides.
This alignment typically happens during the full moon and new moon phases.
The increased tidal range and stronger currents associated with Spring tides can lead to hazardous coastal conditions, as seen with the current weather warning.
Spring tides occur twice each lunar month all year round.
However, the intensity of the tides can vary, and during periods of rough sea conditions, the impact can be more severe, posing significant risks to those near or on the water.
