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.
Volunteer crew members from Criccieth's RNLI lifeboat station assisted in the rescue of a young porpoise calf.
The calf had become separated from its mother and was beached on Black Rock sands by the time the lifeboat arrived. Two lifeboat crew members entered the water and walked ashore before taking the calf on-board the lifeboat, says the RNLI.
Once safely on-board, the lifeboat sailed to the area where its mother had last been spotted and placed back into the water. The lifeboat then retreated and watched the calf swim away.
A dog was rescued by the RNLI yesterday after it had fallen from the cliffs and into the water at Mewslade Bay on the Gower.
Crews were alerted to the incident at around 6:30pm yesterday evening after they could see the dog swimming in the water, unable to climb back up onto the cliffs.
A lifeboat had to be launched and one crew member was put ashore to rescue the dog, whose owner was standing at the top of the cliffs.
The dog was not harmed in the incident and was later reunited with its owner who was very emotional and extremely grateful to the crew for saving his pet.
A nine-year-old girl was rescued by lifeboat crews from Newquay earlier this evening, after getting her foot stuck between rocks at Aberaeron.
Crews were called out at five o'clock just as the tide was starting to come in.
It was the first call out for 17-year-old RNLI volunteer Tom Evans, the youngest member of the team.
A spokesperson for the RNLI said:
"We commend the bravery of the crew member who removed his jacket and helmet and crawled down into a tight space between sea defence rocks and managed to cut the girl's boot to allow him to pull her out."
"He is the youngest crew member at the station and it was his first proper rescue situation. He performed very well under the direction of the station mechanic."
The girl, who was from the local area, was taken to hospital for routine checks.
RNLI lifeguards will be on duty for the summer season from today at more beaches in Pembrokeshire, Ceredigion and the Vale of Glamorgan.
They will patrol Amroth, Aberystwyth South, Clarach, Borth and Southerndown beaches working in partnership with local councils.
The charity says there have already been numerous rescues as people enjoy recent the hot weather.
As the fine weather continues RNLI lifeguards are returning to some of Wales' most popular beaches in Pembrokeshire and Ceredigion.
They will be on duty, in partnership with Pembrokeshire County Council, at Poppit Sands, Newport, Broad Haven, Newgale south, Saundersfoot, Tenby north, Tenby Castle and Freshwater west beach for the summer season.
Further north in Ceredigion, the charity's lifeguards will be ready at their posts at Aberporth, Tresaith and Aberystwyth North as they continue to work alongside Ceredigion County Council in the seasonal service.
A man was rescued by the RNLI this morning after the boat he was on ran aground on rocks. The boat grounded near Milford Haven just after 5am today, forcing the man, who was in his 40s, to scramble ashore.
An RNLI crew was dispatched to the scene and rescued the man while the sailing boat he was originally on began to break up and become swamped by waves. The rescued man was uninjured and returned safely to Milford Haven.
Two vintage Austin motor cars with a combined age of 159 years will attempt to complete a tour of Wales by driving round the coastal roads of Wales.
One of the drivers, Tony Phillips, is doing the journey to raise money for the RNLI after he was saved during a rowing race across the Irish Sea in 2008.
