Ok, so I go to visit my sister who lives there - but this has enabled me to get to know the island a bit. I've been there 5 or 6 times now (I can't remember!), once in April and the rest of the time at the end of Sept or beginning of Oct. In April it was warm and lovely like a late spring/early summer day, but the sea was cold then - we did still swim though, after all it was about the same temperature it is in
Brighton in August! And the flowers were all out and the countryside looked beautiful! September is better as my sister says the weather can be so hot in July and August that you can't do anything, while in September it's still t-shirt weather in the evenings, and sometimes in the 30's during the day! All the times I've been there it's only rained on one day. My sister says early on this year they had the worst weather they've had since she's lived there, but it's not normally like that... personally, if Easyjet did flights after September, and they were cheap enough, I'd go after then as well!
The other reason I like September is that my sister does have some time off work, things are beginning to slow down, the atmosphere becomes very chilled, most of the lager lads and the club 18-30 types have gone home, but there's still plenty of things happening. Most of the clubs have their closing parties in late Sept, and most of the bars, beach bars and restaurants stay open til after the clubs close. We are going again this Saturday, so a bit later than usual, but it coincides with one of the closing parties, and although it will be 60 euros to get in, we're going! It looked so exciting last year, it was really hard walking away from the club and not going in.... I've been to Pacha before, which was great, even though it was playing particularly cheesy gay Italian house that night! It has so many rooms and is very beautiful inside. My sister used to live in Ibiza town until last year. I liked being there, there were many more opportunities to meet Spanish people and feel like you're in Spain there. Also the Dalt Vila is fantastic, and the Port area too. She moved to be nearer her work last year, to
Playa D'En Bossa, which is one of the main resort areas. If bucket 'n' spade shops and cheesy bars are your thing, then stay there. It's got it's good point though, but if you get an apartment in
Playa D'En Bossa do make the effort to travel around the island as you'd missing out massively if you only stayed there!
San Antonio is the second biggest town and where the notorious 'West End' is - avoid this. The only reason to go there is for sunset at Cafe del Mar (or Cafe Mambo next door). Actually the harbour is quite pretty.
