The Lowdown
G’day, Rusty here. Let’s talk about Osaki Point for the next couple of weeks.
Right now, the surf is small and nothing special. Through the end of July and into early August, we’re looking at waves around 1 ft to 2 ft, coming from the southeast. It’s not much. The period is decent some days – Saturday morning the 25th has a long 16-second groundswell, but the energy is low (148). That long period might make it break a bit straight at a beach-and-reef setup, but the glassy wind early Saturday and Sunday is nice for anyone wanting a clean, tiny wave. Water temp is about average for this time of year.
Saturday and Sunday mornings are glassy, but the swell is tiny but rideable. Monday the 27th onward gets messy with cross-shore winds and storm risk – not worth it. There’s a dry spell from late July right through to the morning of Sunday, August 2nd. Lots of days where the surf is poor or ordinary.
Then things get real from Monday morning, August 3rd. That’s the standout window. Monday morning brings a clean 3 ft ESE swell with a 13-second period, glassy conditions, and energy at 623 – moderate, but quality is good. Monday afternoon gets even better: 5 ft from the ESE, 17-second period, light cross-off breeze, and energy up at 1370 – strong wave energy. That’s perfect for this reef setup, with clean waves and long lulls.
Tuesday August 4th morning is the big one: 8 ft ESE swell, 18-second period, glassy, and energy at 4162. That’s expert territory. Tuesday afternoon pushes to 10 ft and 6612 energy, but gets a bit cross-shore. Wednesday the 5th and Thursday the 6th see massive swell – 15 ft to 25 ft – with energy in the tens of thousands. Too big for this break, with warnings it’s predicted to be too big. Only the most experienced should even think about it.
Best of the best: Monday August 3rd afternoon and Tuesday August 4th morning. Monday afternoon has 5 ft from the ESE, 17-second period, light cross-off wind, and strong energy (1370). Tuesday morning is 8 ft but glassy – a proper standout for experts. Crowds are possible here, so get in early.
After that big pulse, Friday August 7th through the weekend eases into 7 ft to 12 ft range, with SSW swell, shorter 9 to 11-second periods, and mostly glassy or clean winds. Saturday August 8th and Sunday August 9th look excellent – 7 ft to 7 ft SSW, 11-second period, glassy. Energy stays strong (1410-1640). Sunday morning is dead calm – absolute perfection.
Summing it up: first week is a write-off unless you’re desperate for a tiny glassy wave. Real action starts Monday August 3rd and rolls through the next week, with Tuesday August 4th morning and Monday August 3rd afternoon being the standout sessions. After that, Friday through Sunday August 9th still offer solid, clean waves.
Stay stoked,
Rusty.

Information about the Osaki Point Surf forecast
The above surf forecast table for Osaki Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Osaki Point can be found by selecting the local surf guide option on the grey menu. Our Osaki Point surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Osaki Point) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Osaki Point may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
