The longshore current velocities recorded at different stations along the study area are Valinokkam (0.06 to 0.3 m/s), Keelmundal (0.04 to 0.31 m/s), Narippaiyur (0.01 to 0.39 m/s), Kannirajapuram (0.01 to 0.48 m/s), Vembar (0.04 to 0.42 m/s), Pachayapuram (0.12 to 0.40 m/s), Periyasamypuram(0.11 to 0.44m/s), Kalaignanapuram (0.02 to 0.38 m/s), Sippikulam (0.03 to 0.50 m/s), Kallurani (0.10 to 0.50 m/s) and Tuticorin (0.02 to 0.34 m/s), respectively. The breaker zone width ranges from 16 to 20 m with maximum during July, October and November (20 m). One can observe the variation of surf zone width at Narippaiyur from 15 to 22 m with a maximum during April (22 m). Kannirajapuram depicts a variation of the surf zone width from 15 to 20 m with highest during the months of February, May, November and December(20 m). The waves are approaching the coast predominantly from SE (45°) during SW monsoon, NW (20°) during northeast monsoon. Since the orientation of the shoreline long the study area is in general NS-EW direction, the waves hits the coast between N 110° and N 135° are of greatest significance in conjunction with littoral processes.
