The Lowdown
Alright, folks, Rusty here. Let’s get into it. We’ve got a pretty quiet spell ahead for Osaki Point, but patience is going to pay off in a big way.
Right now, the water is sitting at a warm 84°, which is a touch warmer than usual for this time of year. It’s a nice feeling when you’re just sitting out there waiting.
The next few days are a real struggle. From Sunday the 26th of July right through to the 2nd of August, we’re looking at a long stretch of flat, weak, and confused little waves. The swell is tiny, mostly under 2ft, and the energy is pathetic – we’re talking values as low as 30 to 187. It’s basically a lake. There’s a little window on the 29th where we get some glassy conditions in the morning, but the swell is just too small to get excited about. You’d be better off with a longboard and a whole lot of patience.
Now, hold onto your board. Things start to change around the 3rd of August. The swell starts to build, but it’s still a bit messy with cross-onshore winds. By the morning of Tuesday the 4th of August, we’re looking at 7ft of groundswell from the ESE, with a very long period of 16 seconds. The wind is glassy, and the energy is a massive 1947. This is the real deal. The swell is getting solid, but at over 7ft, this is for the experienced crew only. Beginners should sit this one out.
The absolute standout is the morning of Friday the 7th of August. The forecast is for 16ft of ESE groundswell with a period of 17 seconds, and the wind is glassy. The energy reading is a staggering 12774. This is exceptional, expert-level surf. The swell direction is right in the sweet spot for Osaki Point, and with light, offshore winds predicted, it’s going to be as clean as it gets. This is the one you wait for. The only caveat is that with that long period, the sets will be powerful and a bit walled-up at this beach-and-reef setup, so keep your wits about you.
The 8th looks like it might be too big for the break itself, with 20ft swell predicted, but the following days on the 9th and 10th of August drop back to a much more manageable 3ft to 4ft with clean conditions. A solid end to the run.
Stick with it, the wait is worth it. This is Rusty, signing off.

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.
