Business leaders were forced to take cover from torrential rain just before King Charles was due to join them for a posed photograph in Nairobi.
"Retreat! Retreat!" could be heard on a news camera feed as guests hastily made their way back inside, where the photo opportunity was to be relocated.
An organiser joked: "We tried - at least you got a picture with me!" which amused some of the guests.
Buckingham Palace and British Embassy staff hastily came up with a 'Plan B' to protect the monarch and the business leaders from the strong wind and rain.
King Charles was in his element, touring a Tech and Innovation showcase at Nairobi Garages.
For more than half a century, His Majesty has championed both sustainability and young people and this engagement combines both these passions.
Nairobi Garages has been dubbed the 'Silicon Savannah' and Kenya is currently the third largest start-up eco-system in Africa.
His Majesty met young entrepreneurs who are, according to Buckingham Palace, "at the forefront of the country's thriving technology sector".
Start-up businesses dedicated to public health, pollution and climate action all spent time with King Charles, undeterred by the bad weather.
An education expert has suggested young African entrepreneurs could have huge benefits to the UK economy, and King Charles' visit shows how his soft-diplomatic power and high profile can strengthen relations between Britain and Kenya.
Professor Chris Imafidon, an education expert who attended the Kenyan reception at Buckingham Palace last week, told GB News: "Africa represents a new renaissance when it comes to economic contribution. It's strengthening ties between Kenya and the United Kingdom."
"The UK right now has to depend on outsourced [technology jobs] to fill the skill gap, the talent shortage we have. So what do we do? It is best to reach out to youths."
"In Kenya, there is so much youth unemployment. So you can see that the youth unemployment there will be taken care of by our technical needs in the West. So it's a win-win situation."
King Charles and Queen Camilla are in Nairobi at the start of a four-day State Visit to Kenya, as the country prepares to celebrate 60 years of independence from Great Britain.
