Conditions at 13th Beach in April
April: The Sweet Spot Arrives
April is when 13th Beach starts to fire with more consistency. The Southern Ocean westerly belt begins shifting northward, delivering more robust frontal systems and a steady supply of long-period groundswell. Average wave height ticks up to 5-6ft (1.6m), and the average period lengthens to 12.3s - a genuine long-period signature. The waverose is now a full-on SW show: SW accounts for 47% of the wave energy, SSW for another 20%, and WSW for 9%. The wind regime also swings in the surfer's favour: offshore winds from the N, NNE, NE and NNW quadrants account for 22.5% of observations, while the onshore SSE-SW component falls to under 30%. Ideal surfing wind reaches 25%, and with the combination of long, powerful groundswell and a higher percentage of clean mornings, April delivers a significantly better wave quality. Water temp is still pleasant at 17.0°C and air temps average 15.6°C, so the wetsuit gets a bit thicker but conditions are far from harsh.
