The Lowdown

Alright, this is Rusty, and I’m looking at a pretty flat spell to kick things off, but there’s a little fire on the horizon if you’re patient.

We’re talkin’ about Osaki Point. It’s a beach and reef setup that’s consistent, but the swell is nowhere to be found for a while. From Thursday the 23rd through Friday morning the 24th, the combined energy is a weak 36 to 67, with tiny 1ft waves from the east and southeast. The water’s a warm 84°F, which is a touch warmer than normal for this time of year. Friday morning the 24th is glassy, but with only 1ft, it’s nothin’ to paddle out for.

We’re in for a long stretch of nothing. Through the weekend and into the next week, it’s the same story: small 1ft to 2ft swell, with combined energy mostly under 200. There are a few glassy mornings – Saturday the 25th, Sunday the 26th, and Monday the 27th – where the waves are “surfable but very ordinary.” You might find a knee-high bump, but it’s not much. The period is mostly between 8 and 15 seconds, but the size just ain’t there.

The real standouts are way out in the second week. Monday the 3rd of August starts to show some life. By the afternoon, the swell jumps to 3ft from the ESE with a long 16-second period, and the combined energy hits 561. That’s moderate energy, and it’s the first real sign. The wind is a light cross-onshore, so it’s not perfect, but it’s a step up.

Then, Tuesday the 4th of August gets serious. The morning brings a solid 7ft ESE groundswell with a very long 17-second period, and the combined energy is a strong 2682. That’s big, powerful, and long-period. The wind is light onshore, but the afternoon has a light cross-shore. For a beach and reef spot, that long period stuff might make it a bit straight, but the energy is undeniable. This is for experts only – over 8ft, that’s heavy.

Wednesday the 5th of August is the absolute best on offer. The morning bumps up to 8ft from the east, with a 16-second period and a massive combined energy of 3782. That’s very strong wave energy. The winner is the afternoon: 8ft of east swell, still 16 seconds, but the wind shifts to a light cross-offshore from the southwest. The wave comment says “excellent surf conditions for experienced surfers.” That’s the one. When you get 8ft of clean, groundswell with that kind of energy and offshore wind, it’s a special session. It’s a long way out, so confidence is lower, but it’s a serious date.

After that, Thursday the 6th and Friday the 7th back off quick, with the swell dropping and onshore winds pickin’ up to 22 mph, makin’ a mess.

So, the next week is a write-off for any real surf. The big action is centered on Wednesday the 5th of August, particularly the afternoon, when the east swell and offshores line up perfectly. That’s the one you want to dream on, but don’t cash in your chips yet – it’s a long-range call.

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.
