The Lowdown

Righto, let's have a look at what's on the table over the next couple weeks for the region around Osaki Point.

To be straight up with ya, the first week or so is a patience game. We've got a long stretch of tiny, weak energy rolling in. From Thursday the 23rd of July right through to about Saturday the 1st of August, the swell is hanging around a pathetic 0.3m to 0.5m (1 to 2 ft). The combined energy is mostly in the low double digits or triple digits, which is just not enough to get excited about. Most of these days are a write-off, with poor surf conditions or just surfable waves but very ordinary conditions. You'll see some glassy mornings, like Saturday the 25th and Sunday the 26th, but there's simply no power behind the waves to make it worth paddling out.

Now, we do get a little bump in consistency around Tuesday the 29th and Wednesday the 30th of July, but the swell is still small (0.5m to 0.7m / 2 to 2 ft) and the period is short, around 8 seconds. The energy flirts with the 100s, but the wind and conditions just aren't coming together for a proper session. The water temperature is about average for the time of year, nothing unusual.

The real story, and the only true standout in this whole 16-day window, is the run from Sunday the 2nd of August through Tuesday the 4th of August. This is where it all comes alive.

Sunday the 2nd of August shapes up nicely. Early morning we've got 0.9m (3 ft) of swell from the ESE with a 16-second period, and the combined energy jumps solidly. The wind is glassy. By the afternoon, it steps up to a clean 1.1m (4 ft) from the E, also with a 15-second period, and the energy is even stronger. This is a solid groundswell, and with those light offshore or glassy conditions, Osaki Point will be clean and fun. This is the pick of the early part of that run.

But Monday the 3rd of August and Tuesday the 4th of August are the heavy hitters. We've got a proper swell arriving. Monday morning brings 1.9m (6 ft) from the E with an 18-second period. The combined energy is massive – that's strong. The wind is a light cross-onshore in the morning, but the afternoon cleans right up with a cross-offshore breeze from the south, and the waves push to 2.1m (7 ft). That's excellent surf conditions for experienced surfers. Tuesday the 4th of August is the absolute peak. Morning brings 2.3m (8 ft) from the east, 18-second period, with very strong wave energy. The wind is light cross-offshore, making for clean conditions. This is a big, powerful groundswell, and it's going to be a challenge. The swell is over 2.5m (8 ft) for the experts on this day, so if you're not solid, find a channel. The afternoon eases a little to 2.2m (7 ft) but is still a ripper. After this, it slowly fades back into small, ordinary conditions through the rest of the week.

So, if you can wait, the clear standouts are the afternoon of Monday the 3rd, and the morning of Tuesday the 4th of August at Osaki Point. The swell direction for that whole window is from the E and ESE, which matches the optimum swell direction for the break about as well as you could ask for. It's a beach and reef setup, and with that long period (15-18 seconds), it will be best on the reef sections where the energy can focus. Crowds are sometimes an issue there, but with this size, expect the better surfers to be out.

That's the story. A quiet start, then a few days of outstanding, big, powerful swell that will demand your respect.

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.
