Conditions at Whangapoua Beach in April
April: The Hidden Gem Month
April often flies under the radar, but the numbers give it real value. The average period is still 8.1s, tied for the best of the year, and the favorable N-NNE-NE-ENE window sits at 52%, with ENE at 25% and NE at 16% leading the way. The swell is small on average - 1.5ft (0.5m) - but the period and direction work together better than in most other months. The wind regime is also friendlier: SW and WSW combine for 25% of observations, while the wider offshore flow from S through WSW totals 34%. Ideal clean conditions are still only 2% of the time, but the frequency of workable morning windows improves.
Autumn rains start to arrive with 2.83mm/day, and air temperature drops to 17.9°C while the ocean still offers a pleasant 19.6°C. April is a transition month - less consistent than February, but with a better chance of finding a punchy NE-ENE swell groomed by a southwest wind. For Whangapoua, that makes it a solid late-season option.
