The glorious weather is bringing a lift to both to people's spirits and to the numbers out and about at Welsh resorts.
But as the sun and the start of the summer holidays coincide with a lifting of Covid restrictions in England, will this cause confusion for visitors?
Wales still has indoor social distancing laws in place and a requirement to wear face coverings.
So how have visitors from England and retailers from the Welsh seaside resort of Rhyl been coping with Wales' rules?
The Beach Shop is hoping for an economic boost from the warn weather, where Diane Simons was helping her daughter run the business on Rhyl's seafront.
Ms Simons said the weather had helped sales, adding: "We're very grateful for it. We've waited a long time.
"People ask if you have to wear a mask in the shop and they have been very good. Obviously not everybody abides by it but most people do."
