Margara seasonal overview
Best Surf Season (October – March)
The North Pacific winter pattern delivers the most consistent swell energy to Margara during this half of the year. Average wave heights range from 1.4m to 1.8m, with periods between 6 and 7 seconds – rideable and punchy. While the dominant swell direction remains ENE (often producing long, weak lines), occasional pulses of north-northeast and even northwest swell wrap into the north-facing beach, offering the best opportunity for lined-up sets. The trade-off comes with wind: offshore breezes from the south to southwest are rare, but the often light cross-shore flow from the east can keep conditions clean when speeds stay under 10-20 kph. October stands out with the highest percentage of ideal wind (52%), making it the prime month for quality.
Fair Surf Season (April, September)
Transition months see a drop in average swell height to around 1.4-1.5m and periods hovering near 6 seconds. The swell angle shifts even more to the ENE, reducing the chance of northwesterly energy. However, lighter wind regimes and a slightly higher frequency of south component winds (up to 48% ideal in September) create some windows of fun, groveling conditions. April’s average height of 1.5m can still produce a few punchy waves when a short-period ENE pulse aligns with light offshore flow.
Low Surf Season (May – August)
Summer brings the smallest and weakest swell of the year to Margara. Average heights drop to 1.2–1.3m with periods of 6.0–6.3s, and the swell direction is almost exclusively from the east-northeast (ENE accounts for 55–77% of all waves). This oblique approach rarely breaks cleanly on the north-facing beach, often resulting in weak, closeout sections. While the wind is ideal 35–49% of the time (mostly light east or southeast winds), the lack of size and poor swell angle makes these months primarily a low-energy period best suited for longboarders or beginners. Only occasional tropical swells or distant low-pressure remnants might briefly elevate conditions.

Conditions at Margara in September
September: Autumn Awakening
September marks the beginning of the transition toward more consistent swell. Average height holds at 1.3m but period increases slightly to 6.1 seconds. The swell direction begins to shift: ENE drops to 50.2%, NE rises to 27.6%, and NNE (10.2%) and even north (2.1%) start to reappear. This is a promising sign as the North Pacific storm track slowly becomes active. Wind conditions improve significantly, with ideal wind 48% of the time. The wind rose shows more frequent light SSE (2.6%), S (1.9%), and SSW (1.3%) winds, offering cleaner conditions. While the majority of swell is still oblique, the occasional NNE pulse can produce fun, rideable waves in the 1-1.5m range when combined with a light offshore. September is the month when surfers start watching the forecast again.
