Oscar Point - surf spot statistics

Best Surf Season (March)

March stands out as the most favorable month at Oscar Point, offering a rare combination of solid swell and the highest likelihood of offshore winds. The South Pacific storm track delivers a steady diet of SSW and SW groundswells averaging 1.6m with a long period of 13.5s, providing powerful, well-shaped lines off the southern reef. While winds are dominantly onshore from the S-SSW direction, a slight uptick in N to NNE breezes occurs 6% of the time, cleaning up the faces and creating momentary windows of perfection. This is the month to watch for short-lived but epic sessions when the stars align.

Fair Surf Season (February, April, November)

These shoulder months offer a mixed bag. February sees similar swell quality to March (1.5m, 13.1s) with 4% offshore wind chances, making it a decent backup. April boasts the largest average swell of the year at 1.7m and a deep 13.6s period, but ideal wind drops to 2%, so waves often arrive with a lumpy, onshore texture from the prevailing S-SSW airflow. November still pumps consistent SSW swell (1.6m, 13.0s) but offshore wind is virtually non-existent (0%), limiting quality to early mornings when the seabreeze hasn't kicked in.

Low Surf Season (May - October, December - January)

This extended period is dominated by strong, persistent onshore winds from the south and southwest, blowing directly into this SSW-facing beach. From May through October, average swell heights reach their annual peak (1.8-1.9m) with periods of 12.8-13.6s – the Southern Hemisphere winter roars to life. However, ideal offshore wind occurs less than 1% of the time, meaning the vast majority of days are characterized by choppy, wind-affected conditions (WSW swell is minimal, but onshore winds shred the wave face). December and January see slightly smaller swell (1.4-1.5m) and wind patterns that are only marginally better – a rare N or NNE breeze may appear 1% of the time, but typically the onshore flow wins. For the dedicated surfer, patience and a sharp eye on high-pressure systems that can bring light north winds are essential; otherwise, the spot remains a high-performance challenge only when nature cooperates.

March: The Golden Window

March offers the best chance for quality surf at Oscar Point this year. Average swell height jumps to 1.6m with a 13.5s period – powerful and well-organized. The swell direction is heavily skewed toward SSW (83.1%) with a smaller SW component (16.1%), but the key is the percentage of offshore wind 6%, the highest of any month. Light N and NNE breezes (0.2% from N, 0.2% from NNE) can align with high-pressure cells to create glassy conditions. However, onshore winds still dominate: S (22.4%), SSW (25.8%), and SW (22.2%). When the offshore hits, expect clean, long-period waves with hollow sections and steep faces. The ocean is alive with winter swell energy, and the brief windows of favorable wind are worth chasing. Monitor Madden-Julian Oscillation phases that can suppress the usual south wind.
