www.google.com/maps/@-10.8875393,122.8183489,1687m/data=!3m1!1e3 All of the the breaks to the west and south are offshore with the trade winds. The wind is predominantly from the east and north east, very rarely you get a south east but it all changes during the day and the strength too like most of indo. South east wind gives side shore access to the south and a bit of the west breaks

I hear in July the wind gets over 35knots with guys only using 6m kites. The American runs Nembrella Beach Resort and is a really nice guy. Like all surf breaks kiters shouldn't get in the way of surfers. If you can kite cross off or offshore you should enjoy it, the wind comes over relatively flat land and has a long flat reef, that you can often walk over, to smooth it out. To the east there is an onshore beach
www.google.com/maps/@-10.9228186,122.8586138,1781m/data=!3m1!1e3 that gets a wind swell, which I hear is good when the winds get much stronger. There is some reefs to the far north east

The east side doesn't get any swell until it is big as well. Even Boa
www.google.com/maps/@-10.9421336,122.850569,782m/data=!3m1!1e3 which should be kiteable is often flat and offshore on north easters. Most of Rote gets relatively small swells compared to the rest of indo and is highly dependent on the direction of the swell. I was told a break to the north near nembrella on the west side lines up with the wind well, the islands also look good but not many locals have powered boats...so you would probably have to pay a lot or make friends. Almost no places have any signs advertising accommodation, because the local government taxes them for it if they do. Most of the places near main area on the beach are accommodation and also most places with walls, you need to ask around and not many people speak english, but May is not busy at all because the swells aren't good. Rocking up with no previous bookings is not a problem like most places in indo, as long as it's not the national holiday time.
