Car stranded in the sea on busy Bank Holiday at Oxwich Bay in Wales

A tractor had to drag a car out of the water after it became submerged in the sea yesterday.

Beachgoers saw water "pour" out of the vehicle's doors as the tractor hauled it from the bay. The car, pulling a boat, was driven onto the beach at Oxwich Bay on the Gower in south Wales as families relaxed on the sand.

It reversed the boat into the water, but for some reason the car continued to reverse into the water too. One beachgoer said: "The car kept going, with all the onlookers questioning why it was going in so far... They released boat and trailer and couldn’t get the car to start or move."

Beaches were packed at British coasts yesterday as the mercury peaked at 29.3C. Photographs show seasides particularly busy in Bournemouth and Brighton.

It was also busy along the south Wales coastline. The witness at Oxwich Bay continued: "A trailer or tractor-looking vehicle had to come and pull the car from the sea, with water pouring from the doors as it went. When it was pulled to the beach the car wouldn’t start so it was dragged completely off the beach. No one was hurt or injured, was just an unusual thing to see on bank holiday." Photographs show the car stuck near the sand.

Beachgoers were also shocked when a car was spotted in the sea at Amroth Beach in Pembrokeshire, south Wales on Thursday afternoon. On this occasion, it was unclear how the vehicle became stuck in the water.

Speaking to Wales Online, a witness said: "I honestly don’t know how it got there. There were lots of people on the beach just looking but most people were just getting on with their day, swimming just up from it, in their kayaks. It was bizarre. "

The 29.3C peak yesterday, recorded in Ross-on-Wye, Herefordshire, was the hottest day in a recehnt warm spell. However, forecasters warn temperatures will fall this week and rain is coming, in part due to the impact of Hurricane Erin which has dodged the US. A deep area of low pressure - bringing violent thunderstorms - is barreling towards the UK, and is likely to cause havoc on Wednesday.

The Met Office website reads: "Low pressure will dominate the weather for the remainder of the week bringing showers or longer spells of rain. It often looks breezy too." The heaviest of the rainfall is thought to happen across Northwest of England, meteorologists understand.
