Probably not that many (yes I've operated from SOU for years before you ask). If it's foggy in SOU it's normally below 550m so unless a CAT II is installed the current RVR restriction is largely irrelevant. Many airfields in the UK operate without a CAT II system, EXT, CWL, LCY, ABZ, BHD to name a few. I use SOU as one of my primary alternates virtually every day and it's rarely a marginal decision, it's either completely out or I can use it.
I Would love to know the answer to that question, I wouldn't be surprised if it was the most fog affected airport in the country. 3 days in a row last week for a start. No point paying a premium to fly from your local airport if you are end up diverted 140 miles away at 11pm at night like some people were last week.
