Fairweather Football Fans.

[Robbie 𝕏 @Robbie_NCFC]

Quoted from AI Google with it's answer to the question. What is a fairweather football fan?

"A fair weather football fan is someone who only supports a team when they are winning & loses interest when they are losing. The term "fair weather fan" comes from the analogy between good weather & trouble-free times. 

Fair weather fans are often the subject of study by scholars interested in the psychology of sports fandom. Some things that researchers have found about fair weather fans include: 

They tend to have a lower level of allegiance to the team than die-hard fans.

They may distance themselves from the team when they perform poorly, describing the team as "them" instead of "us".

Die-hard fans may view fair weather fans as traitors to the team.

The term "bandwagon fan" is sometimes used interchangeably with "fair weather fan". However, a bandwagon fan may jump to support a different team that is successful or trendy, whereas a fair weather fan only engages when their current team is doing well". 

Is this a fair analogy of the fair weather football fan or is there more to it than this?

It's probably fair enough. However, I think it's natural to feel more enthusiastic during a promotion race or when battling the drop, crowds rise at those times for a reason. It would be nice if everyone kept attending come what may, but that's not the world we live in. You've also got more casual fans who have an affinity for Notts but are more likely to come when they're being entertained. It takes all sorts!

As for bandwagon fans, many people who are now die-hard fans started off as bandwagoners. Not so very long ago, the average age of supporters at Meadow Lane was very high - probably because of the large number of pipe-smoking old boys who had started coming when Tommy Lawton signed and had gone on to become loyal and lifelong fans. No doubt the odd Notts fan in the 1940s grumbled about the bandwagon jumpers who just wanted to see Lawton play, but those of them who were still coming in the 90s definitely earned their stripes!

Well I don’t think you can call me a bandwagon fan, I started supporting Notts when they were in the old 4th division, I have to admit to being a bit of a fairweather fan these days in the sense that if the weather is wet or cold or both I’m less likely to go to watch Notts and would rather stay in the warmth of my living room either watching them on telly if they are on or listening to them on the radio, it’s an age thing with me.

Perhaps a more apt description are "armchair fans". Economics can play a part, as "fair weather" fans may only attend a number of games a season  and maybe have family commitments too.

Northern Ireland fans tend to be either Liverpool or Man U. These are armchair fans, geographically distanced.

The strength of the Premier League, one can get school kids following the big clubs as they want to be associated with success, when perhaps their local teams miss out ( maybe the parents too are not interested in football).
