LONDON, May 14 (Xinhua) -- Perfect weather is expected Saturday when Prince Harry and his bride-to-be Meghan Markle marry, Britain's Met Office said Monday.
Forecasters said the weather is looking ideal for the Royal Wedding at Windsor Castle, expected to be watched by a global audience of millions.
The latest forecast for Windsor for Saturday is almost perfect for the crowds gathering to watch and for Queen Elizabeth's grandson and the soon-to-be Princess Meghan.
Deputy Chief Meteorologist Chris Tubbs said: "We expect some warm, sunny spells, although, at this early stage, there is some uncertainty about just how much cloud we can expect during the day.
"Early temperature forecasts suggest that the day will start rather cool, with an early morning temperature of around 6 Celsius, so anyone who arrives early to get a good place in the crowd will need to wear something warm. The maximum temperature in Windsor on Saturday will be around 20 Celsius, compared to an average for the time of year of around 17 Celsius".
Meanwhile the Household Cavalry Mounted Regiment, which will provide an escort for the newly weds, continued Monday to make preparations for the big day.
"It will be a matter of huge pride and professional honor for the soldiers responsible and work is already underway behind the scenes to ensure they deliver a performance to make the nation and their brother officer proud," said a spokesperson for the British Army.
Prince Harry joined The Blues and Royals in April 2006 and served with the Household Cavalry Regiment, serving operationally in the frontline in Afghanistan and rising to the rank of Captain.
Some of the soldiers who trained and served with the Prince will be supporting him on his wedding day, either riding in the escort or lining the steps of St George's Chapel at Windsor Castle where the marriage service will take place.
"The sovereign's bodyguard, the Household Cavalry, will selflessly sacrifice themselves to protect the monarch and her heirs," added the British Army spokesperson.
