March at K59 brings consistent surf with an average swell height of 1.1m and a strong period of 14.4s, ensuring powerful, well-formed waves. The dominant swell direction is from the SSW, contributing over 80% of waves in the 0.5-2.5m range, with the best consistency in the 1-1.5m range (51.41%). Smaller swells from the S and SE add variety but are less frequent. Wind conditions are ideal for surfing 47% of the time, with the most favorable winds coming from the NE to ESE at light to moderate speeds (0-20kph). However, stronger NNE winds (20-30kph) can occasionally create chop, affecting wave quality. Overall, March offers reliable, punchy waves with good shape, especially on days with lighter offshore or cross-shore winds. Advanced surfers will find the most opportunities when the SSW swell aligns with lighter winds, while intermediate surfers should watch for smaller S or SE swells on cleaner days.
