Union Island

Union Island is the southernmost inhabited island of Saint Vincent and the Grenadines, a small (about 9 sq km) volcanic island with its own international airport. JT Pro Center, founded by professional kiter Jeremie Tronet, runs two distinct riding areas: a protected, knee-deep, clear flat-water lagoon for first lessons, and a larger open flat-water zone for longer freeride sessions - plus boat-supported excursions out to Tobago Cays and Mayreau. Hurricane Beryl (July 2024) caused major damage to the island's infrastructure; check current rebuild status before planning a trip.

Monthly wind statistics

Station: Port Elizabeth, Bequia (weatherspark.com (NASA MERRA-2 reanalysis climatology), ~48 km) — Windfinder.com 429'd on every attempt (session-wide issue, see fuwairit note). No weatherspark coverage exists for Union Island itself; nearest covered location is Port Elizabeth on Bequia, ~48 km north (a different island in the Grenadines chain, but same open Atlantic trade-wind exposure, so likely a reasonable proxy). Windy season late Nov-early Aug with average speeds >15.1 mph, peak Feb 17.3 mph; calmest Sep 12.8 mph. Direction 'from the east throughout the year' -- classic steady Caribbean trades, consistent with the batch's known best-months (Dec-Jun). No Beaufort-probability or per-month wind-speed table available, so avg_knots/prob_ge_4bft_pct left null.
