White Plains Beach - surf spot statistics

Best Surf Season (May - September)

Summer brings the south swell season to life at White Plains Beach. Optimal swell directions from the SE through SSW dominate during these months, with May and September peaking near 30% of all swell energy arriving from that quadrant. Wave heights average a fun 1.5m with periods in the 10-12s range, offering rideable, punchy waves. The wind regime, however, is a trade-off: the persistent ENE trade winds blow over 70% of the time, creating a side-offshore cross-breeze that grooms the waves nicely. While true offshore (N-NNW) winds are scarce (8-19%), the consistent side-offshore flow keeps surfaces reasonably clean. This is the go-to window for dependable, shapey surf on the south shore.

Fair Surf Season (April & October)

The shoulder months of April and October present a transitional blend. South swell percentages drop to 15-19%, but the mix of lingering winter north swell and early/late summer pulses can produce occasional standout sessions. Average heights hover around 1.5-1.6m, with periods still solid around 11-11.5s. Offshore wind percentages improve to 16-19%, making for cleaner surfaces when the wind aligns from the north. These months reward patient surfers who can read the charts and pounce on southerly windows between the trade wind onslaught.

Low Surf Season (November - March)

Winter transforms the North Pacific into a storm factory, sending massive NW and N swell trains toward the Hawaiian Islands. Unfortunately, White Plains' south-facing orientation largely blocks this energy. Dominant swell directions are from the N through WNW, contributing over 60% of the wave energy, yet these swells arrive heavily refracted or flat. Average heights remain decent at 1.7-1.8m thanks to the north wraparound, but the quality suffers from long-period, disorganized lines. On the bright side, offshore north winds are most frequent (21-26% ideal), so when a rare south swell undercuts the winter pattern, conditions can be epic – but those days are few and far between.

October: The Autumn Shift

October is a true transitional month. South swell percentage drops to 19.3%, while north swell begins its seasonal increase (NW now 3.5%, NNW 4.1%). Average height stays at 1.5m, period 11.5s. The trade winds fade further (56.3% ENE), and ideal north wind rises to 19%. The mix of lingering south swell and building north wraparound creates a diversified wave menu. The best days come when a south pulse aligns with a north wind – that combination yields clean, punchy surf in the 1-1.5m range. October rewards surfers who stay flexible, as conditions can change quickly from summer to winter patterns.
