North Point seasonal overview
Best Surf Season (March - May)
As autumn settles in along the Australian coastline, North Point comes alive with a potent mix of consistent swell and favorable offshore winds. The Southern Ocean storms become more organized, sending long-period west swell pulses directly into the spot's west-facing lineup. Average wave heights hover in the 1.9-2.3m range with periods often exceeding 12 seconds, offering powerful and rippable surf. Crucially, the percentage of ideal offshore winds (from the east quadrants) peaks during this window, reaching 25% in both April and May. This is when a strong high pressure cell frequently parks itself over the Tasman Sea, funneling clean east-northeasterly breezes across the coast. The combination of solid groundswell and glassy conditions makes this the prime time for scoring North Point at its best.
Fair Surf Season (June - October)
Winter deepens, and the Southern Ocean roars to life, unleashing the largest swells of the year onto the West Australian coast. From June through August, average wave heights climb to 2.6-2.8m, and periods stretch beyond 13 seconds, delivering heavy, long-period energy. The dominant swell directions shift solidly into the SW and WSW quadrants — perfectly aligned with North Point's exposure. However, the wind patterns become more challenging. The percentage of offshore wind drops to around 17%, as frequent frontal passages bring westerly onshore winds. The quality of the surf then becomes a game of patience: waiting for a transient ridge of high pressure to deliver clean east winds between systems. Spring months (September-October) see a gradual decline in swell size but an improvement in wind consistency as the subtropical high strengthens.
Low Surf Season (November - February)
Summer in the Southern Hemisphere brings a lull in the storm track, and North Point feels the impact. Average swell heights drop to 1.8-1.9m, and wave periods shorten to the 11-12 second range. While the west-facing orientation still captures any remnant groundswell, the energy is less consistent and often smaller. The dominant wind flow becomes more variable, with a higher frequency of sea breezes and light onshore conditions. The percentage of ideal offshore wind falls to just 13-15%, making clean sessions a rare treat. During these months, the best chance for surfable waves comes from a strong low passing far south in the Indian Ocean, sending a pulse of west swell while a morning offshore gradient sets up. It's a time to be selective and chase the windows.

Conditions at North Point in September
September: Spring Transition and Power
September straddles the change from winter to spring, still delivering solid 2.6m average swell at 13.2s periods. The swell direction stays west-oriented, with SW (28.4%), WSW (15.9%), and W (3.5%) providing excellent exposure. Wind patterns remain challenging, with ideal offshore wind at 17%, but the ratio of onshore vs. offshore starts to shift. The wind roses show a slight decrease in pure westerly flow and an increase in SSW and S winds, which are cross-offshore for North Point. The strengthening spring sun also triggers more consistent land/sea breeze cycles, occasionally creating glassy mornings before the seabreezes kick in. It's a month of potential – big swell is still around, and the windows for clean waves are gradually expanding.
