On the water

Delta-style water body with flat to choppy conditions. Brackish and murky water, pleasant temperature in summer (18-22°C/64-72°F). Shorty or 3/2 wetsuit depending on season. Muddy and shallow bottom. Tidal currents run through the area but remain manageable. The thermal wind creates regular surface chop in the afternoon.

Hazards

Power lines crossing the water body — absolute attention to jump height and trajectory. Very strong thermal winds (25-35 knots) with gusts that can surprise. Tidal currents in the channel. Pilings and submerged structures. Earthen levees creating wind turbulence. Motorboat traffic on weekends.
