April: The First Real Transition Month

Average height remains at a healthy 5-6ft (1.7m), and the average period strengthens to 9.2s, giving the waves more penetrating power on the bank. Water temp drops to 24.5°C, rainfall eases to 3.19 mm/day, and the air feels noticeably less tropical.
Clean windows become more reliable as ideal wind frequencies rise to 31%. S/SSE groundswell is still often mixed with SE trade-wind swell, but westerly and northwesterly winds in the wake of Tasman lows increase in frequency. When the morning W/NW breeze meets a fresh S/SSE swell, South Wall Ballina can produce unexpectedly good, hollow walls.
