Kirra - surf spot statistics

Kirra, Australia, is a world-class right-hand point break that thrives on consistent ground swells and favorable winds. The best months for surfing at Kirra are typically from March to July, when ground swell percentages peak, averaging 20-29% of the time, and wind conditions improve compared to other months. March stands out with 20% ground swell, 29% good wind conditions, and a solid 1.7m mean swell size, making it one of the most reliable months. April and May continue this trend, with ground swells holding at 20-25% and good wind conditions reaching 34-37%, while June and July still offer decent ground swell energy (28-29%) despite slightly smaller waves (1.5-1.6m). The worst conditions are from November to February, when ground swells drop below 16%, wind swell dominates (84-88%), and bad wind conditions peak at 73-81%. September to December sees the smallest waves (1.4-1.5m) and the lowest likelihood of clean conditions. For powerful, well-shaped waves and manageable winds, target mid-autumn to early winter (March-July), avoiding the summer months when onshore winds and weak swells prevail. Kirra’s legendary barrels are most likely in this window, especially when larger SE swells and lighter E/NE winds align.

July at Kirra offers fairly consistent surf with an average swell height of 1.5m and a decent period of 9.4s, ensuring good energy and rideable waves. The swell direction is predominantly from the south and southeast, with the most frequent waves in the 1-1.5m range (peaking at 10.43% from SSE) and solid overhead potential (1.5-2.5m+ waves occurring around 11-12% of the time from SSE and S). While smaller swells (0.5-1.5m) dominate, there are still regular mid-sized to larger days for advanced surfers. Wind conditions are somewhat inconsistent, with only 33% of days offering ideal offshore (W/NW) or light cross-shore winds. The prevailing winds come from the S/SSW and tend to be moderate (10-30kph), which can create bumpy conditions, but early mornings often see lighter winds. Overall, July delivers fun, mid-sized waves with periodic clean conditions—best suited for surfers comfortable in varied wind and capable of handling occasional punchy swells.
