King Charles delighted approximately 500 members of the public with an unplanned walkabout through heavy rain in Grimsby town centre on Thursday.
Sheltered only by an umbrella and wearing a light grey suit without a coat, the monarch spent roughly 15 minutes greeting crowds and discussing the weather conditions.
"I'm so sorry you got so wet," he told the drenched well-wishers as he shook hands.
Just as he prepared to depart by car, cheers from another group behind barriers prompted him to extend his engagement, walking over for additional conversations with those who had waited in the downpour.

Prior to the walkabout, Charles had visited the Horizon Youth Zone, where cheering crowds of around 100 people greeted his arrival despite the wet conditions.
Inside the modern facility, he engaged with schoolchildren, armed forces cadets and scouts, touring the climbing wall, sports hall and training kitchen.
The monarch observed teenagers preparing pizza muffins and enquired whether they minded missing lessons for the occasion.
"I have my uses," he quipped when one girl mentioned she had avoided maths class.

During his time in the sports hall, Charles expressed regret at being unable to play badminton and asked youngsters about Grimsby Town's memorable Carabao Cup triumph over Manchester United last August.
His boxing gym visit concluded the Horizon Youth Zone tour, where he watched young people training.
The facility, which opened in February, caters to those aged eight to 19, extending to 25 for individuals with additional needs, offering everything from sports and cooking to performing arts and employment support.
The centre forms part of the Grimsby Together initiative, a grassroots regeneration programme now serving as a model for communities nationwide.

Charles then proceeded to The CARE Hub, a community care and housing organisation providing support through a safe, nurturing environment.
Specialist designers created the centre's welcoming atmosphere, resembling a comfortable sitting room.
There, the King met staff and service users, including a private conversation with Liam Atkinson, 26.
Mr Atkinson shared how his life unravelled following the breakdown of his marriage and subsequent health difficulties, losing both his home and employment within 12 months.

The CARE Hub helped him rebuild, and he now has his own flat where he lives with his three-year-old son.
"They changed my life. All the staff here are absolutely amazing," he said. "The help and support is absolutely unbelievable."
Reflecting on his encounter with the monarch, Mr Atkinson described Charles as approachable and compassionate.
"He's so down to earth. He's so kind. So considerate," he said. "He seemed to care, which is amazing."
