last weekend I went myself to Palu to check out the condition and the promise of this new place. I can tell that all is thrue, the people there (not kitesurfer) recon that they have about 300 windy days in a year.
Out of the 4 I was there 3 was windy around 20 knots, the only day with out wind was due to rain and Palu is one of the dryest place in Indonesia. Also really cheap to stay, the beach is not really pretty and the water is little bit choppy but like every place when you get 20 knots in open sea.
I think I will recommend a visit to people passing bye in Indonesia for a 3 - 4 days hi wind experience. Palu is exactly 80 kilometers from the equator and the temperature is year around 30 degree and the water 28 degrees. To get there you can fligth from most of the big cities in Indonesia via Unjung Pandang.
In the future we will organize weekend from Bali and we will open a page in our web site http://www.geocities.com/kitesurfbali
