About this spot

About

Mantasaly (Ocean Dunes) in Andovokongo Bay is a resort-based kite destination built around consistently strong Southeast trade winds. The launch area is a wide sandy beach with easy access for rigging and launching, and water conditions can be very flat in the bay while still offering medium-wave options for riding. During the main season (May through October), wind is reported as extremely reliable, with typical ranges around the low-20s up to the mid-30s knots. Wind is often reinforced through the day, building from mid-morning and continuing through the afternoon—making it well-suited for long sessions when the breeze is steady. Water is described as clean and warm year-round, with sandy bottom sections that are generally easy for entry and maneuvering. However, the lagoon can include coral heads in specific areas, particularly at low tide, so riders should plan around tide/reef zones and consider protective footwear when walking near shallow coral. Safety-wise, the main cautions are avoiding coral heads, being prepared for strong winds, and managing side-offshore components in parts of the bay (flat water can still mean you need support if you lose upwind position). Also be mindful of other beach users in the peak months and verify access rules/any required permits before going on the water.

  • Very consistent trade-wind kitesurfing window (May–October)
  • Shallow flat water inside the bay and wave potential on the outer reef
  • Warm water year-round (mid/high-20s °C)
