Lifeboat crews rescue girl who got her foot stuck between rocks at Aberaeron.
The crossing warnings are being trialled by the RNLI which has had to rescue hundreds of people who have been cut-off by the tide.
The two Austin cars have a combined age of 159 and are attempting to visit as many lifeboat stations as they can.
RNLI lifeguards return to their posts around Wales this Easter weekend and have reminded beach-goers to be aware of the dangers.
From 10am the charity's lifeguards will be present at Aberavon, Neath Port Talbot, Whitmore Bay in Barry Island and Tenby South beach to offer advice and assistance to beach-goers.
All three beaches kept the lifeguards extremely busy in 2013.
Whitmore Bay was the busiest Welsh RNLI lifeguarded beach for the second year running as the lifeguards responded to 221 incidents and assisted 236 people.
"RNLI lifeguards are trained to respond to a range of incidents both on the beach and in the water," said Stuart Thompson, South Wales RNLI Lifeguard Manager.
"We work with the Ambulance Service as First Responders to deal with minor and major first aid incidents, rescue people from rip currents as well as assisting other emergency services to help search for missing children.
"It was great to see thousands of people enjoy the hot weather on Welsh beaches last summer and hopefully we'll see more of the sun again this year.
"When enjoying the coast we advise people to try and visit a lifeguarded beach and to always swim or bodyboard between the red and yellow flags - this is the area that's patrolled by the lifeguards.
"If you get into trouble raise your hand and shout for help; or if you see someone else in danger please don't try and attempt the rescue yourself - tell a lifeguard or call 999 and ask for the Coastguard."
Two teenagers were rescued by Porthcawl RNLI after they were cut off by the tide at Llantwit Major.
The two teens rang 999 on Sunday evening after becoming stuck below cliffs, but weren't sure of their exact location leading to a search being launched by two lifeboats from Porthcawl.
Both boys, who were wet and very cold, were taken to the Barry Dock, where they were met by paramedics.
Porthcawl Lifeboat operations manager Philip Missen said: "This was a testing callout for our crews, but with a very successful outcome in saving both casualties.
"Fortunately they did have a mobile phone and were able to make that important call for help. We would recommend that the public should always check the tide times before walking in areas where it is possible to be cut off by the incoming tide."
The RNLI in Moelfre was launched to help rescue a family stuck in the mud at Red Wharf Bay.
When they arrived at the scene, two of the three family members had managed to make their way ashore.
Time was of the essence; as the individual was only meters from the incoming tide and had been trapped for almost two hours. The volunteer crew liaised with the local coastguard team from Moelfre, and it was confirmed that two of the three family members were safely ashore. The third person could be clearly seen waist deep in mud, but access was hindered due to the depth of the surrounding silt.
A coastguard mud rescue specialist was sent to the scene, and working together the lady was finally extracted from the mud with only minutes to spare, before the incoming tide covered the area she was trapped.
A rescue helicopter from RAF Valley was on standby, but was stood down as local ambulance crews assessed the casualty, who was later released fit and well.
A new home for the RNLI's Tamar class lifeboat was officially opened on Mumbles pier today. The boat house is the first part of a wider regeneration of the seaside village. Alexandra Lodge reports.
The new boathouse for Swansea's Tamar-class lifeboat will be given a royal seal of approval today, when it is unveiled by the Duke of Kent.
The boathouse, which is sited at the head of Mumbles Pier, is a key feature in a joint regeneration and restoration project for the 113-year-old pier.
It will be house the £2.7m Tamar-class lifeboat that was unveiled in October last year.
The Duke of Kent, who is president of the RNLI, will officially open the new boathouse later today and also dedicate the lifeboat, which is to be named RNLB Roy Barker IV.
The vessel is named after Frederick Roy Barker, from Jersey, who died in 1992, bequeathing his whole estate to the RNLI, with the request that the monies be used to fund new lifeboats.
Hundreds of lifeboat volunteers from across Wales found themselves experiencing one of the RNLI's busiest years last year.
Figures released today show that the long, hot summer brought people back to the beaches.
The weather also brought a rise in incidents compared with 2012, with over 1,700 call-outs.
The RNLI also saw a 23 per cent increase in the number of people rescued, with lifeboat crews coming to the aid of almost 2,000 people.
Aberystwyth RNLI Lifeboat crew have rescued a man they believe was taking photographs of the waves. Despite public warnings to stay away from the coastline, it seems the man walked to the end of the wooden jetty. Rescuers say he became trapped due to the force of the waves.
At 10am on 4th January the lifeboat was called in after the police and coastguard were unable to get to him. He was rescued and returned safely to the RNLI boathouse.
In a statement, a spokesperson for Aberystwyth RNLI Lifeboat said:
“Whilst the extreme sea conditions are attracting people to the coastline, we repeat our warning to the public stay safe and to keep away from the shore line and dangerous waves."
The RNLI has released this video of their efforts to help re-float a minke whale stranded on Pensarn Beach, Abergele. The 20-foot whale was eventually freed and made its way back to open water on Monday evening.
A 20ft minke whale stranded for two hours close to Pensarn beach in Abergele this afternoon has been successfully re-floated.
It swam back out to open sea aided by coastguards and RSPCA officers.
Main and inshore lifeboats from Rhyl were also at the scene.
Coastguards waded chest-deep in the sea and gently prodded it away from the beach.
Volunteers of a lifeboat station on Anglesey have been enjoying a remarkable day - getting to meet up with some of the many people whose lives they have saved or helped over the years. The reason is to show why the RNLI needs a new boathouse at Moelfre.
