Currently in Mallorca and hardly any topless women.
I expected a small percentage
(Maybe 10%) but it's far less.

Beachs in Torrevieja
 

Recently on holiday in Torrevieja I’d say 10% or less topless on the beach. Shame.

Didn’t bother my wife she was topless everyday and even at the pool where no one else was, she even swam and walked around without her top. No one was bothered by it.

I do think if people see others doing it they’re likely to follow suit- a few other women at the beach near us decided to take their tops off after we sat near them.

Mallorca
 

One thing I noticed, we were on the island during the storm of this week.
After the storm, much more women went topless. As if they realized they best "make the best" out of the sunny days of their holiday.

Never thought about it, but it really was a big difference. Still only maybe 10% though.

When I was in Spain last year I'd estimate that 1 in 10 sunbathed topless. I didnt look around much to make a proper scientific analysis because angry girlfriend.

Yes, I think it's a subtle set of factors in play. The same location can have a great run of spots one day, then nothing on another day. Weather is definitely a key factor: you want it sunny and still, but not so hot that people are covering up and flaking out. But there clearly are times when the right kind of people are on the beach and feel comfortable enough to push the boat out, and times when they aren't and don't.

I am right now at a beach about one hour from Barcelona. Don't know the percentage but there are a lot women topless. It's the most normal thing in the world there. Been to France before and there were much less women topless.
Advantage at cote de azur is that you get to see more fake tits, which I am absolutely into.
Yesterday at the beach.... Sitting on my towel... Looking to the right: six young women in their twenties, three of them topless.
Looking to the right, two women topless.
Lots of them go topless into the water, topless beach walk etc.
Love it.

In France , espcially at the Lavandou, there are many in July and less in August.

Has someone been in Maspalomas ? What's going on there ?

Asses
 

Women are now too busy showing off their asses in thong bikinis. It's all good.

Costa Brava from two hours ago.
Beach is full of topless women...

We need more pics as evidence.
