i loved september this year, much better than july in my opinion
So did I, as regards the clubbing thing, but not the weather during the 10 first days of the month, which was horrible last year. Rain, floods, dull skies most of the time, heavy swell, even some little cold nights....Didn't have much time to enjoy the gorgeous beaches. However it was a strange weather as even though storms are common in September, that bad weather was odd for that month.
There are much less people than in August, above all tourist families. Less clubbers, but the change is not so big than for family tourism, as you still will see the harbor bars full of people at night for example. And in general the clubbers in September are much more open-minded and nice. During these days the only party I was at which I found too packed to enjoy was Pure Pacha. The rest were very crowded in general, crowded enough to their expectations (or mine).
Maybe the weakest days in September are in the middle of the month, just after all the people who goes on holiday at the beginning of September, and just before the most important closing parties.
