Yallingup • Surf Spot Statistics

Best Surf Season (April - May)

As the Southern Ocean's storm belt begins to shift northward through April and May, Yallingup finds its sweet spot. Average swell heights hold in the 6.5-7.5ft (2.0-2.3m) range, average periods reach 12.8-12.9 seconds, and the percentage of ideal offshore wind climbs to 28 percent in April and 26 percent in May. Long-period SW and WSW groundswell wraps around Cape Naturaliste into the west-northwest-facing reefs while ESE/SE winds groom the faces, producing the cleanest, most powerful combination of the year.

Fair Surf Season (March and September - November)

The shoulder seasons offer plenty of opportunity, but the ocean is less consistent. March still has warm water and lighter winds, though average heights sit around 6ft (1.9m). September through November sees the tail end of winter's deep-water energy, with swells averaging 6-8.5ft (1.9-2.6m) and long periods, but the ideal offshore wind window drops back to 18-19 percent. Cold fronts and W/SW wind shifts can spoil sessions, so timing the post-frontal SE flow is critical.

Low Surf Season (December - February and June - August)

Two distinct windows test the patience of Yallingup surfers. In summer, the Southern Hemisphere storm track retreats poleward and swell averages dip to 6ft (1.8-1.9m) with periods around 11.9s, producing clean but underpowered surf. In winter, the ocean is firing with 8.5-9ft (2.6-2.8m) swells and 13s periods, but persistent W/NW onshore winds batter the coast and the ideal wind window falls to just 17 percent. Both seasons are low in clean-surf probability; if you can pick the days, winter offers the heaviest slabs while summer offers small, groomed reefs.
