Conditions at Cat Bay in April
April: Transition In The Air
April marks the beginning of the autumn transition. Average swell height rises slightly to 1.5m (4.9ft) and the average period lengthens to 12.5s, so there is more energy in the water. However, the clean-wind percentage slips to 37% as synoptic systems begin to shift. The swell distribution still favours SW at 52.0%, but WSW jumps to 13.3% and W to 3.6%, showing a more westerly flavour in the groundswell. The most notable change is in the wind: NNW becomes the single most frequent wind direction at 11.3%, with NW and WNW adding another 11.3%, so onshore winds are beginning to challenge the offshore S/SW flow. When the morning S/SSW breeze kicks in, expect groomed 3-5ft (0.9-1.5m) waves with good period; by afternoon, the NNW sea breeze can turn things messy.
