hi guys, been lurking on the site many years. finally have something to contribute.
mate of mine owns a budget hotel opposite Shipwrecks. you can see the break from the bar & restaurant, and from a couple of the rooms. Two local boats anchor directly in front & will take you to any of the breaks. Also dive/snorkling/fishing trips are pretty cheap. You usually paddle/wade back if you're surfing Shipwrecks. Other breaks they'll either hang around or arrange a time to come back for you.
wind is generally onshore in January, but mornings especially can be light or glassy. crowds won't be anything like high season. It's easy to get around & you'll get plenty of waves.
mainski-lembongan-resort.com/Brian's the main man. most of the staff are locals. All types of food but Aussie standards re cleanliness, etc. Have fun.
