Lefthanders - surf spot statistics

Lefthanders, Australia, is a world-class wave known for its powerful and consistent ground swells, offering some of the best left-hand barrels in the region. The spot benefits from a high percentage of ground swells year-round, ranging from 92% to 97%, with almost no days of flat conditions. The swell size varies seasonally, peaking in the winter months (June to August) with mean swell heights of 3.5-3.7m, making this the prime time for experienced surfers seeking heavy, hollow waves. The shoulder seasons (May and September) still provide strong swells (3.1m and 3.6m respectively) with slightly more manageable conditions, while October through April sees smaller but still solid waves (2.3-3.0m), better suited for intermediate surfers. Wind conditions, however, are a limiting factor—onshore winds dominate throughout the year, with good wind days peaking at only 24% in April and May. The best balance of size and favorable winds occurs in March, April, and May, when ground swells remain strong (2.4-3.1m) and the chance of good winds rises slightly to 20-24%. For those chasing the biggest and most powerful waves, June-August delivers the largest swells, but the high percentage of bad winds (83-85%) means patience is required. Overall, the optimal window for the best combination of swell size, consistency, and slightly better winds is from March to May, though dedicated surfers will find quality waves year-round if willing to wait for the right conditions.

December at Lefthanders offers solid surfing conditions with an average swell height of 2.3m and a healthy 12.7s period, indicating consistent, well-formed waves. The swell distribution is heavily SW-dominant, with the majority of waves (22.51%) arriving in the 2-2.5m range from this direction, supported by strong contributions in the 1.5-2m (18.70%) and 1-1.5m (6.83%) brackets. SSW swells also contribute, particularly in the 1.5-2m and 2-2.5m ranges, while S swells provide smaller but still surfable waves. The wind is less favorable, with only 13% of conditions being ideal for surfing—primarily when lighter offshore winds from the W-NW quadrant prevail. However, the prevailing SE-SSE winds (often 20-30kph) are onshore and can create choppy conditions, especially during stronger gusts. Surfers should target days with SW swell and lighter W/NW winds for cleaner, more organized waves, though larger swells (2m+) will be frequent. Pack a step-up board for the punchier days.
