Charles and Camilla, known as the Duke and Duchess of Rothesay in Scotland, toured the BBC's Glasgow headquarters as the broadcaster marked its own diamond anniversary: 60 years of television.
They were shown the news studio by presenter Sally Magnusson and introduced to the BBC Scotland weather team.
Charles was then invited to read a specially written weather bulletin with references to royal residences in Scotland.
He said: "It's an unsettled picture as we head towards the end of the week. This afternoon, it'll be cold, wet and windy across most of Scotland.
"There'll be snow for the higher ground of the Highlands and Aberdeenshire – the potential for a few flurries over Balmoral as the afternoon goes on."
Camilla then read the same forecast in the studio.
After their trip to BBC Scotland, the couple travelled to the City of Glasgow College to meet young people taking part in the Prince's Trust's Get Into Cooking Programme.
Aimed at 16 to 25-year-olds, the programme is designed to give youngsters the skills and experience needed to work in the hospitality sector.
The couple donned cooking aprons and hats, and joined students making canapes for a royal reception.
Laura Dey began the course on Monday and said: "It's pretty cool to be cooking for royalty in my first week.
"I was quite nervous this morning but they were really nice. I was showing Prince Charles how we make the desserts but he didn't want to try any of the chocolate.
"Maybe he doesn't have a sweet tooth."
Before leaving the college, The Duke and duchess met former students and local employers at a Prince's Trust reception and were presented with a three-tier cake students had made to mark the Queen's Diamond Jubilee.
