Union Island - Frigate Island
Saint Vincent and the Grenadines
Union Island
Frigate Island, just south of Union Island in the Grenadines, is a small islet accessible only by boat or by kite. It is an isolated spot popular for its ultra flat water and its wild setting surrounded by mangroves.
Ten minutes from the JT Pro Center in Clifton, there is a small sandy beach for takeoff or you can launch directly from the boat. The atmosphere is calm, away from the crowd, perfect for progressing at your own pace.
The spot is suitable for beginners as well as freestylers, with a typical paradisiacal backdrop of the Grenadines.

Informations utiles
chop
flatThe wind typically blows offshore or side-off relative to the lagoon, creating ultra flat conditions ideal for freestyle and learning. Launching is done from the small sandy beach or directly from the boat, with a limited but easily accessible takeoff area.
The navigation area is a shallow protected lagoon, perfect for jumps and tricks, but it can become a bit choppy at high tide. For waves, you need to go upwind towards the reef or Palm Island, accessible in a few tacks.
The spot is remote, so plan for a safety boat from Union Island. It's a must for a downwinder from Clifton, with turquoise water and generally few people.
The ideal directions are ENE, E, ESE, confirmed by locals and guides, for pure offshore wind in the lagoon. Optimal strength between 15-25 knots for flat and powerful sessions.
The water is generally ultra flat and shallow in the lagoon, perfect for freestyle. At high tide, it becomes slightly choppy, while at low tide it remains flat but with less space.
The currents are weak in the protected lagoon, but be careful near the reefs where they can accelerate. Tides influence the water surface, with more chop at high tide.
Opt for 9 to 12m² kite sizes in the medium winds of the Grenadines, smaller like 7-9m² on strong days, and 11-13m² if light. Adjust according to your weight and style.
The dominant trade winds come from ENE, E, ESE, with an average strength of 15-25 knots from November to July. The wind is steady and consistent, particularly strong in the dry season from December to May.

The trade wind season runs from November to July, ideal for kiting, while the months of August to October are wetter with possible showers.
The depth is gradual and shallow in the lagoon, with foot depth for a long time due to a sandy bottom. Ideal for falls without risk.
The water temperature varies little, around 27°C in the dry season (December-May) and 29°C in summer. A short lycra is sufficient all year round.
