April: Winter Swell Meets Consistent Offshore Flow
April is when the stars align more regularly. Wave heights average 6ft (1.8m) with periods of 10.7s - genuine groundswell. The S direction dominates at 24.9%, but SSE (15.5%) and SE (10.9%) round out an excellent spread of swell angles for Mangamanu. The wind story improves markedly: ideal offshore winds blow 58% of the time, with NW and NNW directions combining for over 25% of the rose. This translates to many more clean, grooming days. The cool autumn air (avg 12.7°C/55°F) and 14.1°C (57°F) water are a small price for increasingly firing surf. This is the start of the high-quality window for more experienced surfers.
