The Lowdown
Alright, Rusty here, let’s break down what’s going on at Osaki Point.
First few days are flat and forgettable. Starting Monday, July 27th, water temp is 29° – that’s a touch warmer than normal for this time of year. The waves are tiny, like 0.4ft to 0.7ft, glassy in the morning but still ordinary. Nothing to get excited about. Tuesday and Wednesday stay small too – all under 2ft with light winds but no punch.
Things stay minimal until Sunday, August 2nd. That afternoon we finally see a pulse – 0.5ft from the east-southeast, but with a long 16-second period, and energy picking up to 275. Not rideable yet, but the ocean is waking up. Monday the 3rd brings better size: around 5ft from the east-southeast with a 15-second period and energy hitting 813. It’s cross-onshore so not perfect, but surfable for those who are keen.
That leads into the real highlight on Wednesday, August 5th. Morning session shows 10ft of east-southeast swell, 17-second period, glassy calm wind. That’s massive, long-period groundswell. Combined energy is 4943 – strong. This is excellent for experienced surfers, but the long period might make it a bit straight for this beach-and-reef setup. The afternoon holds at 10ft with cross-off wind and energy over 5400. If you can handle it, this is the window.
Thursday the 6th pushes 12ft, but with onshore wind – still big, but messy. Friday the 7th hits 16ft to 18ft from the east-southeast and energy over 20,000 – that’s enormous, way too big for this break. Might be a kite-surfing day. Through the weekend we’re looking at 32ft to 39ft surf on Saturday and Sunday – that’s a monster swell. Even the most experienced locals will be watching from the beach.
After the peak, Monday the 10th is down to 12ft but cross-onshore. Tuesday the 11th drops to 5ft from the south-southwest, 12 seconds, with cross-off breeze – clean, manageable, and solid for experienced surfers again.
Best bet? Wednesday morning, August 5th, glassy and 10ft – that’s the call. But be aware, it’s a long way out, so keep tracking it.
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.
