Lennox Head - surf spot statistics

Lennox Head is a consistent surf spot with year-round waves, but the best conditions for surfers typically occur between April and August. During these months, ground swell frequency increases (peaking at 32% in July), reducing reliance on wind swells, which are less powerful and organized. The mean swell size remains steady around 1.5m-1.6m, providing a good balance of size and rideability. Wind conditions also improve significantly in this period, with good winds (offshore or light cross-shore) occurring 29-39% of the time—highest from May to July—while bad winds (onshore or strong cross-shore) drop to their lowest levels (61-71%). Outside this window, particularly from November to February, surf quality declines as wind swells dominate (81-86%) and good wind days become scarce (15-18%). Swell size slightly diminishes in late spring and summer (1.4m-1.5m), further limiting ideal surfing opportunities. For the most reliable, cleanest waves with solid ground swell and favorable winds, mid-autumn to late winter (April-August) is the prime window at Lennox Head.

December at Lennox Head offers surfable conditions with an average swell height of 1.4m and a decent period of 8.5s, providing consistent, rideable waves. The dominant swell directions are from the east and southeast, with the highest frequency of waves in the 1-1.5m range (12.57% from E, 8.08% from ESE, 6.52% from SE). Larger swells (1.5-2.5m) are less common but still present, particularly from E, ESE, and SSE. Clean conditions are somewhat limited, as only 17% of the time does the wind align favorably for surfing—typically light offshore winds from the west or northwest. However, northerly and northeasterly winds are more frequent and can create choppy or onshore conditions, especially at higher speeds (10-30kph). Expect the best sessions early in the day before winds pick up, with the most reliable waves coming from easterly swells. Overall, December delivers surfable waves, but wind quality is inconsistent, requiring selective timing for optimal sessions.
