Hi, I've just come back from costa teguise myself and love it there. The average temperature for septemeber is 25 degrees and yes you will need suncream, the wind can be deceiving too so be careful. I have been to CT twice and spent most nights on both holidays at Saxos Family Fun Pub and the Dolphin Inn.Saxos; the staff there are so friendly and they have entertainment everynight incl. Drag Shows, Live Music, Magicians etc. There is also pool tables and bowling alley there. The dolphin Inn have family quizes everynight except thurs, incl Family Fortunes, who wants to be a millionaire etc.. all free with prizes. The Market Square is also a great place at night with live music. There is a nice selection of restaurants and an Irish Bar. Costa Teguise has a great selection of restaurants, most very resonable prices especially the chinese. We payed €7pp for all you can eat chinsese buffets (3 courses) very nice! The name of the restaurant was Jumbo i think (dwn stairs from saxos). The main beach of CT is called Playa Las Churcharas although we prefered the smaller beach, Playa del Jablilloneade. Both beaches are connected by the promenade. If you have any questions please ask and Have a great Holiday!!
