St-Prime is located on Lac-Saint-Jean, a large freshwater lake in Quebec's Saguenay region. The spot features a residential shoreline with sandy beaches and shallow water extending from developed areas. The coastline faces east toward the water, creating a narrow band of usable riding area between residential development and shallow zones. With average winds of only 6.8 knots and 6.4% reliability, this spot operates at the margin of kitesurfing feasibility and requires optimal conditions. Northerly winds provide the best side-shore approach for safety. The shallow water, marshy areas, and residential obstacles make this primarily suitable for beginner riders in very light wind conditions. Limited fetch and narrow riding zones restrict maneuver space. Water temperatures around 4°C suggest seasonal riding limited to warmer months. This spot is best suited for local kiters with intimate knowledge of water conditions and wind patterns, or as a learning location during rare optimal wind windows.
