#Mosselbay - Images: About 200 seal pups washed up on beaches in the Mossel Bay area. #roughsea #springtide #surfsurge
About 200 seal pups have washed up on beaches in the Mossel Bay area. This is a normal occurrence when rough sea conditions is experienced. However please do not swim in areas where seal puppies have washed up on beaches. There is the possibility of an increase in shark activity due to the abundance of food. There is no shark nets at beaches in Mossel Bay and bathers must adhere to lifeguard warnings. It is overcast and cool today in Mossel Bay. Rather visit Mossel Bay shopping emporiums and other interesting areas today. Local authorities are currently busy collecting the baby seals. The public should under no circumstances collect or touch baby seals as they can inflict a severe bite. Reports have also surfaced that people are taking baby seals home. This is an illegal practice. Rather assist the local authorities in telling them where baby seals are located. The public can call SAPREC Wildlife Rescue Service, Address: Voorlopersingel, Mossdustria, Mossel Bay, 6500 Phone: 082 364 3382 for assistance.

MSBWX National Severe Weather Observations: ------Nil
MSBWX General Weather Observations: Cool, warm to very hot conditions expected today over parts of SA. Thunderstorms and rain showers can be expected in parts of Gauteng, Mpumalanga, Limpopo, North West, Northern Cape, Free State and Kwazulu Natal. Isolated to scattered showers and rain expected in parts of the Western Cape, Southern Cape and Eastern Cape by this afternoon, evening and overnight. A cold front is expected to move in over parts of the Western Cape bringing with it colder weather, light rain, strong wind and rough seas. Holiday makers are advised to take note of the changing weather and the expected rough sea conditions that co-insides with New Moon Spring Tide. Boaters, paddlers, sail boarders and anyone launching any kind of craft onto water are advised to stay ashore until the cold front has passed and sea conditions improved.

NSRI National Warnings: SPRING TIDE RIP CURRENT WARNING: With more people on the beaches over the festive season NSRI are urging the public to be extra cautious between now and the New Year with the New Moon Spring Tide, which peaked yesterday, that will cause stronger than normal rip currents around the coast. NSRI are urging extreme public caution around the coast until into the New Year. The NEW MOON SPRING TIDE peaked yesterday, 22nd December. Very strong rip currents will be present around the coast over the next 6 to 8 days. Bathers and shoreline anglers are most at risk and extreme caution is advised Spring Tide happens twice every month, at full moon and at new moon. Spring Tides bring a higher than normal high tide and a lower than normal low tide, causing stronger than normal rip currents, for a few days leading up to the full moon OR new moon, peaking on the day of the full moon OR new moon and lasting for a few days after the full moon OR new moon. There are two high tides and two low tides every day. During Spring Tide the twice daily high tides are higher than normal and the twice daily low tides are lower than normal and while rip currents are always present and dangerous the Spring Tide creates stronger than normal rip currents and hence the danger is increased. Rip Currents are caused when the water reaching the shoreline in waves, swells and sea currents needs to find a way to retreat back into the sea and this is achieved in rip currents (a river of water retreating through the incoming swells back out into the sea). There are two types of rip currents, permanent rip currents, found alongside islands, rocky outcrops jutting into the sea, at river mouths, in between reefs and alongside harbour walls and piers, are found constantly occurring in the same place allowing the water reaching the shoreline to retreat back into the sea in the permanent rip current. Temporary rip currents, found along beach fronts (along the shoreline), are forever changing their position and are unpredictable and can form suddenly along a beach front without warning at different places along the shore front throughout the day. During Spring Tide these permanent rip currents and temporary rip currents are stronger than normal and although rip currents at all times pose a danger to bathers they pose the greatest danger during the Spring Tide. Bathers are at risk of being swept out to sea by rip currents while swimming or wading in water along the beach front. Even bathers wading in shallow water who find themselves trapped in a rip current that forms suddenly are at risk of being swept out to sea by rip currents. Bathers caught in a rip current should not panic. Simply stay afloat by treading water (moving your arms and legs in circular movements), don’t try to swim against the current as it will only cause you exhaustion and let the current sweep you out to sea but at your first opportunity swim parallel to the beach front until you are free of the rip current and then use the incoming waves to get back to shore. While this is happening scream for help and wave your arm to alert people on the beach to raise the alarm. Swim at beaches where lifeguards are on duty and obey the instructions of the lifeguards and only swim within the safe swimming zones lifeguards mark (using their red and yellow flags). Children should have responsible adult supervision at all times around coastal and inland waters and at swimming pools. Anglers fishing along the shoreline, particularly along rocks on the shoreline, are at greatest risk during the Spring Tide where incoming waves during the high tides engulf higher than normal over rocks. Anglers should not turn their back to the sea and should be vigilant and cautious of the wave action at all times while fishing. Boaters, paddlers, sail boarders and anyone launching any kind of craft onto water should wear their life-jackets at all times while on water and carry easily accessible safety equipment - red distress flares, communications cellphone or VHF radio with fully charged batteries in water tight plastic sleeves, a waterproof torch, highly visible neon coloured clothing, a referee whistle worn around the neck, a silver emergency foil blanket, and let a responsible person know your time of departure, your exact intended route and your estimated return time, stick to your plans and check in with the responsible person on your safe return. (If you are overdue the responsible person should raise the alarm without hesitation).

Huge seas at Knysna (15 June 2014)
Below are some photos sent to us by our crew from the Knysna base.
The seas are so big that the base’s storm gates have washed away and the
boat shed has been completely flooded.
According to the South African Weather Service: High seas with wave heights from 6 to 9m is expected between Cape Agulhas and East London at times.

Beware: March 2014 Equinox and High Tides
Image: Waves at Umdloti, Kwazulu Natal in March 2007 (Click on image for larger view.)
With equinoxes comes very high tides. These occur a day or two after the full or new moon nearest to the equinoxes. Equinox tides combined with strong winds and high seas caused by a cyclone off the coast of Madagascar resulted in severe damage along the Kwazulu Natal coast in March 2007. The entire east coast of KwaZulu Natal was subjected to the awesome natural force of giant 10m waves and it took a violent lashing from the power of the sea.
Be prepared for high tides and people living
close to coastal and tidal areas should expect the highest tides of the
year this week. The weather is a major influence on whether the
tides will cause problems. However, it is important that everyone living
on the coast or in a tidal area is aware of the risk and is prepared. Bathers should be very cautious of rip currents normally associated with high tides. Several drownings occurred recently in Mossel Bay as a result of rip currents. Be aware and do not swim in areas were rip currents are active.
