Wind Days = % of days with 12–35 knot average wind speed (ideal kiting conditions). Based on 4 years of historical weather data.
River mouth area with mixed water conditions
Fortim is a deltaic estuary on Brazil's northeastern coast where a river system meets the Atlantic Ocean. The spot features extensive sandbars, tidal flats, and shallow channels typical of river delta environments. The coastline faces east toward the open ocean, making southerly winds (180°) the ideal side-shore direction for kitesurfing. However, wind reliability is modest at 33.6%, requiring careful session planning. Water conditions are rough-chop with modest 1.18m average waves, influenced by tidal cycles and river discharge patterns. The shallow, shifting sandy bottom creates variable riding conditions and requires awareness of depth changes throughout sessions. Developed areas to the south and mangrove-lined channels to the north present navigation constraints. Best suited for intermediate riders comfortable with variable wind conditions and tidal dynamics. Sessions should be timed around favorable wind windows and tidal stages to maximize usable space and minimize ground contact with shallow sandbars.
