The Lowdown

Alright, let’s break it down. The first week or so is pretty flat and uninspiring, but we’ve got a serious pulse of energy coming in the second week that could make it all worthwhile.

Right now, Osaki Point is pretty quiet. It’s a beach and reef setup that’s exposed to the swell, and for the first few days, we’re looking at tiny, weak waves. The swell is coming from the southeast, but it’s only around 1.0 ft to 1 ft. The water’s a touch warmer than normal for this time of year, sitting at 84°F.

Friday the 24th starts off with a light cross-onshore wind, making for small, rippled conditions. It’s clean enough to get wet, but barely. The combined swell energy is a weak 67. The afternoon improves a little, wind goes cross-off, and the surface cleans up, but the waves are still very ordinary.

Saturday the 25th is the best of the early days. We get a glassy morning, wind from the SSW at just 3 mph, and the swell bumps up to 1 ft from the SE. The combined energy climbs to 148 (moderate), and with a 16-second period, that’s a long-period groundswell. It’s small, but that long period means the waves will have some shape and energy, and the glassy conditions make it look pretty. The afternoon is clean too, with a cross-off breeze. This is the pick of the first week, though it’s still only for loggers or longboarders.

Sunday the 26th holds similar small waves, with a morning clean session and a risk of thunderstorms in the afternoon, but the wind is glassy then, so it’s still surfable.

From Monday the 27th through to Wednesday the 6th of August, it’s a mixed bag of poor conditions, small swells, and onshore winds. There are a few clean windows here and there, like Wednesday the 29th morning with glassy conditions, but the swell is tiny. The combined energy dips to between 48 and 169, weak to moderate. It’s a long stretch of waiting.

Then things change. On Tuesday the 4th of August, the swell starts to build. The morning has 7 ft from the ESE, with a 16-second period. The combined energy hits 2143 (strong). The wind is onshore, so the surf is messy, but the potential is there. By Wednesday the 5th of August morning, we hit the standout. The wind goes glassy, the swell is 8 ft from the ESE, with a 16-second period. The combined energy is a massive 2745. This is the one. For experienced surfers, this is going to be excellent. The long period groundswell and glassy wind will make for powerful, well-shaped waves at this point break. It’s big, over 8 ft, so it’s for experts only. The crowd factor is “sometimes,” so expect some company.

The 6th of August sees the swell peak, with 10 ft from the ESE, combined energy at 4204, but the wind is a cross-onshore breeze, making it less clean. It’s still big, but the quality drops.

After that, it gets wild. The 7th of August is blown out by gale-force winds, and the 8th sees a massive 25 ft to 28 ft swell from the ESE, with combined energy of 40,000+. The wind is offshore, but the swell is simply too big for this break. The file says it’s too big, and I agree – that’s tow-in territory, not paddle surfing.

So, the bottom line: the first week is small and average. The best is Wednesday the 5th of August morning, with a glassy, powerful, 8 ft groundswell at Osaki Point. That’s your window. The rest of the second week is either too big, blown out, or messy.

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.
