The Duke of Cambridge, 31, didn't let the wind and rain dampen his spirit as he toured St John's College where some of his studies will take place.
Dressed in a navy suit and maroon tie, William looked dapper as he chatted away to the university's senior figures. The group strolled around the grounds, with the second-in-line to the throne stopping to admire a plaque commemorating his grandmother the Queen's visit to the college in April 2011.
Ahead of the start of the course, Kensington Palace confirmed William's attendance and said that the prince was "very much looking forward" to his studies.
The course, which has been specifically tailored for the prince, will no doubt put him in good stead for his future role of running the Duchy of Cornwall — a portfolio of land, property and investments he will inherit from his father Prince Charles.
William will have roughly 20 hours per week of seminars and tutorials, where he will work alongside a select few PhD students. The father-of-one is expected to learn about the issues facing the UK's rural communities and the farming industry.
In September of last year, William completed a three-year tour as an RAF search and rescue helicopter pilot. The Duke and Duchess of Cambridge then relocated from Anglesey to London, where they recently moved in to their 21-room house with baby Prince George.
While William will focus on his studies and live part time in Cambridge, he will travel occasionally to London to keep up his royal duties over the coming months.
