Hi Plummet, thanks for sharing mate. I came to the same conclusion for most islands when studying historic charts with the wind averaging 18-24 knots when blowing. Might leave my 6 meter.... Samoa for example is going off this week 18-25 knots almost every day!
In regard to Mauritius - I've been there. It is just like the pictures and I rate it the best kitesurfing wave in the world. Very long, super clean picture perfect and insanely consistent wind. I've got mates who live there which is always a bonus. On the other side, there is unfortunately very bad vibes surfing. Even if you know locals they cannot help... You get chased out and asked to leave even when there is only 2-3 surfers out with plenty of waves. Nothing was said to the surfers nor were we taking their waves. This "vibe" has also crept into the kitesurfing at one eye. I was there in 2010 when it was still relatively uncrowded for kiting and out of season,. Probably worth going outside the main holiday period for Europe. Also you need to be experienced in kitesurfing bigger waves in cross off shore conditions.
@SaltySinus - thanks mate - I was looking at Port Villa last night and it looks epic. Waves never get really +6ft, but I never really surf plus 6 ft ;-) Definitely worth considering. My thinking is Fiji - fly to Samoa and or Vanuatu. What about accommodation? Will i be the only kiter? I prefer not to kite solo....
There is another island I've been told about in the area, but unfortunately the person asked me not share it which I will respect. Very similar setup to Port Villa.
Thanks again!
