The Alley - surf spot statistics

The Alley in Australia is a surf spot with predominantly wind-driven swells, as the data shows that wind swell percentages dominate throughout the year, peaking at 90% in November. Ground swells are relatively low, never exceeding 29% (July), making this spot more favorable for surfers who prefer shorter-period waves. The best months for surfing are generally between May and July, when the swell consistency improves with 25-29% ground swells and better wind conditions, reaching up to 40% favorable winds in June. During these months, mean swell sizes range from 1.1m to 1.3m, which is manageable for intermediate to advanced surfers. However, the spot suffers from poor wind conditions for most of the year, with onshore winds (bad conditions) frequently above 60%, particularly from December to April when they often exceed 80%. The most challenging period is summer (December-February), where wind swell dominance and unfavorable winds make conditions less ideal. If you're looking for the most reliable surf, aim for late autumn and early winter (May-July), when ground swells increase slightly, and wind conditions are marginally better.

The Alley in March typically offers surfable conditions with an average swell height of 1.4m and a decent period of 9.0s, suggesting consistent, well-formed waves. The swell direction is predominantly from the E (24.48%), ESE (9.88%), and SE (3.27%) within the 1-1.5m range, providing clean, rideable waves with good shape. Larger sets (1.5-2.5m) from the E and ESE occur frequently, offering more powerful sections for advanced surfers. Wind conditions are ideal only 23% of the time, with the best chances coming from offshore WNW-NNW directions, which are light (0-20kph) and help groom the swell. However, SE-SSE winds (often 10-30kph) prevail, bringing cross-shore or onshore chop, especially at higher speeds. Expect a mix of clean morning sessions and wind-affected afternoons—timing is key. Overall, March delivers manageable waves with occasional size, but wind consistency is the limiting factor.
