The Bluff - surf spot statistics

The Bluff in Australia is a consistent year-round surf spot with a strong preference for ground swell, which dominates the wave energy for most of the year. The best months for surfing here are typically from May through August, when ground swell percentages peak at 98-99%, ensuring powerful, clean waves. During these months, mean swell sizes range between 1.6m and 2.0m, with July offering the largest waves at 2.0m on average. Wind conditions improve significantly from May to July, with the likelihood of favorable winds rising to 32-34%, though still outnumbered by less ideal winds. Outside this window, wind conditions deteriorate, particularly from November to February, where bad winds occur over 87% of the time, making these months less reliable despite decent swell presence. Swell consistency remains high throughout the year, with no flat spells, but the combination of larger swells and comparatively better wind odds makes mid-year the prime time for experienced surfers. Early autumn (March-April) and late winter (August) also provide solid ground swells but with slightly less favorable wind conditions. Overall, The Bluff is a high-performance wave best tackled in winter when swell power, consistency, and workable wind windows align.

September at The Bluff offers solid surf conditions with a dominant SW swell direction, providing consistent wave energy and good shape for experienced surfers. The average swell height is 1.9m, paired with a strong 14.8s period, ensuring powerful, well-formed waves. Most swells are in the 1-2.5m range (SW at 20-25% for 1.5-2m), with occasional bigger sets. However, wind conditions are tricky—only 16% of the time is it ideal (likely lighter offshore winds). The prevailing winds are S to SSW, often blowing 20-40kph (8-20% occurrence), which can create choppy or cross-shore conditions. The spot handles bigger swells well but prioritizes dawn patrol sessions when winds are calmer. Pack your step-up board and watch for clean offshore windows, especially after frontal passages.
