Outer Kom - surf spot statistics

Outer Kom in South Africa is a consistent year-round surf spot with a strong dominance of ground swells, which make up the majority of the swell activity, rarely dropping below 75% in any month. The mean swell size is solid throughout the year, starting at 2.5m in January and gradually increasing to peak in July at 3.3m before tapering off again toward December. The best months for surfers seeking larger, well-formed swells are from May to August, where the average swell height exceeds 2.9m, with July offering the biggest waves. However, wind conditions are a limiting factor, as bad winds (onshore or cross-shore) dominate the entire year, with good offshore winds occurring only 10-20% of the time. The least unfavorable wind conditions are found from April to July, where good wind days reach up to 20%, with May standing out as the month with the best balance between swell size and slightly more manageable winds. If you're willing to tolerate challenging winds, the winter months (May-August) provide the most powerful and consistent surf. Conversely, the summer months (December-February) have smaller swells and even worse wind conditions, making them less ideal for high-performance surfing but still surfable for those looking for more mellow waves. Overall, advanced surfers should target the mid-year window for the best combination of swell size and slightly improved wind percentages.

August at Outer Kom delivers powerful and consistent surf, with an average swell height of 3.2m and a solid 12.6s period, ensuring quality groundswells. The dominant swell direction is SW-WSW, contributing the largest share of rideable waves, particularly in the 2-2.5m range (10.04% from SW) and over 2.5m (2.67% from SW). SSW and S swells also play a role, offering a mix of mid-sized and larger waves. Conditions are often sizable, with 47.5% of swells exceeding 2m, making it best suited for experienced surfers. Wind conditions are less reliable, with only 15% of days offering ideal offshore winds (typically E-ENE). However, moderate onshore winds (WSW-WNW) are common, sometimes creating choppy conditions, especially at higher speeds (20-50kph). Windswell interference is minimal due to the spot’s exposure to long-period SW energy. Expect strong, hollow waves when swells align with lighter winds, but be prepared for challenging paddling and currents due to the raw South Atlantic energy.
