Hi
Hard to say , each year is different but I can give some info...
Restrictions are lifted starting Sept. 16 ... No more banned beaches for wind/kite surfers
We still enjoy thermals ... Till mid / end Oct so we usually get 15 or so knots with west winds and nuclear 35 and up when east winds are blowing ... So make sure you bring along all kites you have ( you can also rent locally ) .
If you are from north Europe , a shorty should be fine ( many Brits and folks from Skandinavia kite without wetsuits at all ) , I wear till oct/ nov my 2mm summer wetsuit ( long legs / short arms ) currents can be a bit cold if you drop your kite and have a hard time relaunching it ... It's a questions of personal taste I'll guess ....
Regarding hotels ... Have no clue ... I live 50 km away ( 25 miles ? ) so only go there to kite but this page may help you ...
http://www.tripadvisor.com/SmartDeals-g ... Deals.htmlThey even have an iPad app ... Good site but there many other around the web ...
Maybe some Tarifa local join us and have better ideas ...
Nightlife ? No clue ... Just get out and have fun ... Tarifa is open all year
