The 22-year-old, who started his career with Saints as a trainee, has become the second new arrival through the doors at Wolves' Compton training headquarters in as many days when he penned a three-year deal with the option of a further 12 months.
Hot on the heels of Kevin Doyle's record arrival, the left-sided England Under-21 midfielder signed for the Premier League new boys in a deal believed to worth around £1.2million.
The past 24 hours for Surman could not have been more of a contrast having left a Southampton side on minus 10 points at the foot of League One and facing the prospect of going out business as they continue to search for a buyer.
"It was a big decision but obviously your hand is forced a little bit more because of the state the club's in," he said.
"Southampton didn't force me out but being relegated to League One, and then a club like Wolves coming in for me, it made the decision a little bit easier.
"I've been a Southampton supporter since I was young, my family are from Southampton, my girlfriend's from Southampton, so it was difficult. But you've got to look after your career and move forward."
He continued: "It's a massive contrast - one side has just been relegated to League One with a 10-point deficit and I'm coming to a side that's riding the crest of a wave, that stayed top of the Championship for most of last season and is now pushing to do well in the Premier League.
"I'm excited to be here and to be part of a set-up like this.
"It's a massive move. To come to a Premier League club, and a club of this size, is a fantastic move for me and it's exciting
to get going and to see if I can prove myself in the top flight."
The deal certainly provides cash-strapped Saints with a much-needed injection of funds as they continue their search for a buyer after the Pinnacle group pulled out of talks yesterday.
A Swiss consortium is now believed to be in the running but Surman - who made over 140 appearances for Saints, scoring 18 goals in the process - admits he and the players are pretty much in the dark about what is going on.
Surman demonstrated just how much when Wolves striker and fellow Saints fan Sam Vokes asked for the inside line.
"I had a chat with him this morning, he's obviously as confused about what's going on down there as I am," added Surman.
"You keep updated vaguely about what's going on behind the scenes, they don't try to tell you too much about it because it can affect some players.
"You just hear snippets about what's going on - some people say they're being taken over and then you see it on the news.
"I think sometimes there's no point trying the tell the players what's going on because things can change so quickly.
"We just get on with the job in hand and the background will take care of itself."
Following the club's promotion to the Premier League, Surman becomes Wolves' fourth signing of the summer behind Doyle, Marcus Hahnemann and Nenad Milijas.
