Smiths Beach - surf spot statistics

Best Surf Season (March - May)

As the austral autumn sets in, Smiths Beach enters a sweet spot. Average swell heights climb from 1.9m in March to 2.3m in May, while wave periods hover around 12.5-12.9 seconds, delivering powerful, long-period groundswells. The percentage of ideal offshore winds (from S, SSW, SW, WSW) peaks at 29% in April, meaning more sessions with clean, groomed faces. The dominant swell direction remains from the SW/SSW quadrant, which wraps into the northwest-facing beach, producing lefts and rights that link up along the sand. This is the time to score when the Southern Ocean pumps and the wind gods align.

Fair Surf Season (June - October)

Winter brings the biggest swells of the year, with average heights reaching 2.8m in July and periods extending to 13.3 seconds. These are powerful, XL groundswells capable of pushing through the outer banks. However, the trade-off is a drop in wind quality – ideal offshore conditions occur only 17-21% of the time. Frequent synoptic storms firing up the Southern Ocean also drag strong westerly and north-westerly winds across the region, turning the lineup into a battle of gusty onshores. When a high-pressure system stalls to the south, offshore breezes from the S/SSW return and the beach transforms into a heavy, barrelling playground for the experienced crew.

Low Surf Season (November - February)

The summer months see the surf settle down. Average swell heights dip to 1.8-1.9m, with periods around 11.8-12.2 seconds. While this is still fun-sized and rippable, the consistency of quality swell takes a hit as the Southern Ocean storm track retreats. Offshore wind windows shrink to 17-19% of the time, and the dominant wind patterns shift to more southeasterly and easterly directions, which are side-offshore at best. For those willing to hunt for groomed highlights, early mornings with a light southerly breeze can produce clean, waist-to-head-high waves on the sets. Still, this is the season for a grovel board or a longboard cruise.

November: Summer lull Begins

November sees a drop in average swell height to 1.9m with a period of 12.2 seconds, still in the fun, rippable range. Swell direction remains mostly from SW (38.9%) and SSW (20.0%), with some WSW (13.3%). Ideal wind percentage settles at 19%. Winds become more southeasterly and southerly: SE (11.5%), SSE (15.7%), and S (14.9%) dominate, offering good cross-offshore conditions. However, the swell energy is less consistent and size can be variable. This is a good month for groveling or longboarding on the better days. Still, if a late-season SW swell lines up with a light Southerly, you can score great waves.
