About this spot

About

Mendu is described as a sheltered, sandy, tidal bay with clean water and very shallow depths where you can often touch bottom—making it a strong learning environment when the tide brings enough water. Multiple sources emphasize that usable riding depends on tide height: mid-tide is repeatedly cited as the best window, while at low tide the water can retreat far enough that the area becomes unrideable, and at high tide the beach can become narrow. Wind is primarily reported from southerly directions (S, SE, and often SSE/SW). Providers also note that sea-breeze/thermal effects frequently reinforce the southerly gradient winds on sunny afternoons, typically starting around mid-afternoon and continuing into the early evening. Reported typical wind speeds fall roughly in the 12 to 22 knots range, with steadier conditions described within the thermal window, though gustiness is also noted. Safety considerations are strongly tied to the shallow, tide-fluctuating seabed. Oyster beds are reported nearby, and rocks are mentioned near Stuhan Island—so riders (especially foilers) must confirm sufficient depth and steer clear of hazards. In addition, summer conditions bring heavy crowds and strict restrictions: kitesurfing is reported as forbidden during summer daytime hours in July and August, including a cited 10:00–19:00 window in swimming zones. Overall, the spot’s best combination of accessibility, flat sheltered water, and workable wind is repeatedly associated with spring through early autumn—particularly autumn—and it is presented as a well-known but seasonally restricted location for kitesurfing.

  • Sheltered flat-water bay for kiteboarding
  • Strong dependence on tide for depth and usable launch space
  • Southerly winds reinforced by thermal sea breeze on sunny afternoons
  • Summer daytime kitesurfing restrictions

KitesurfingBest for this spotSkill Level

Sheltered, shallow, flat-water bay conditions are reported as beginner-friendly, with best rideability at mid-tide when depth and flatness are optimal. At low tide the water retreats and the area can dry out, making sessions dependent on tide height.

WingfoilingSkill Level

Wingfoiling is described as possible but constrained by shallow depth and underwater rocks near Stuhan Island; mid to high tide is required for sufficient mast clearance. One source says the spot is generally foil-friendly, while another emphasizes limitations.

Foil Friendly
Limited — Foil use depends strongly on tide depth and avoiding rocks near the island area.
Min Depth
Requires mid to high tide for sufficient mast clearance; shallow/touch-bottom conditions are reported.

Rules of the spot

Beach users have priority. Summer daytime kitesurfing is restricted/forbidden in designated hours and zones.

Restrictions
  • Forbidden all summer (seasonal bans reported by multiple sources).
  • Kitesurfing restricted/forbidden in July and August between 10:00 and 19:00 in swimming zones.
  • During July and August, navigation is strictly regulated and often forbidden between 10:00 and 19:00 in the swimming zones.
Local Tips
  • Arrive around mid-tide for the best usable flat water and depth.
  • Check tide times carefully: at low tide the water can retreat completely and the spot becomes unrideable.
  • Foilers (and any higher-depth-dependent setups) must verify sufficient depth and avoid underwater hazards near the island area.
  • Avoid summer entirely due to daytime restrictions for kitesurfing between 10:00 and 19:00.
