what is the wind like(knot) in different time of the year in changgu bali ?
been in august was light but very consistent
He there,
Bali has not to strong winds. It has been better in Sumatra. Last year it was howling there and great spot. Check out on Google: kitesurf sumatra.
June/July/August are the best months
as you said the wind tends to be light but is consistent.
A board with volume and kite suitable for your weight in 12 knots will normally be OK for Canggu.
Some great waves to be had
I was in Canggu in October last year (all month) and I could have kited at Canggu most days. It's not super windy but guys were riding both twin tips and surfboards and doing really well. I kicked myself that I didn't have gear there, but I just didn't think it would be windy at all.
Was there last week. Windiest day I saw would have been about 12 knots.. Two 14's out. better waves to be had.
