The Lowdown

G’day, this is Rusty.

Let’s cut to the chase: the next 16 days at Osaki Point are a bit all over the place, with a slow start and then a massive pulse of swell that’s only for the brave. The water’s sitting at 85°F, which is about 3°F warmer than normal for this time of year, so it’s a touch warmer than you’d expect.

The first real action doesn’t kick in until Monday the 5th of August. Wednesday morning sees a 16ft swell from the ESE with a 17-second period, and offshore wind from the ENE at 12 mph. The combined energy is a whopping 14683, and it only gets bigger. By Wednesday afternoon, we’re talking 20ft from the ESE, 17 seconds, offshore wind again, with energy hitting 39334. This is expert-only country. The swell direction is lining up nicely with the optimum SSE, and the wave quality is there, but the size is brutal. If you’re a seasoned charger, this is the standout window, but it’s a long-range call so keep that in mind.

Thursday the 6th keeps the big stuff coming – 23ft from the SE, 17 seconds, with offshore ENE wind at 22 mph in the morning and 25 mph in the afternoon. The energy is still enormous at 29784 and 29255. Again, experts only. Friday morning the 7th holds at 20ft from the SSE, 16 seconds, offshore wind, energy at 20218. By Friday afternoon, the swell starts to drop and shift, and the conditions go south. From Saturday the 8th onwards, the wind turns cross-onshore or onshore, the swell direction swings to the SSW, and the quality tanks. There’s a long stretch of poor surf conditions with no real recommendations.

After the 10th of August, the swell drops to around 8ft to 3ft, but the wind stays messy or cross-onshore, and the energy is weak to moderate, ranging from 516 to 3315. It’s a real flat spell. The best of this later period might be Tuesday the 11th of August morning with a 8ft swell from the E, 12 seconds, and offshore ENE wind at 9 mph, but the energy is only 2705 and the forecast is marginal. The 17th of August morning sees an 8ft E swell, 10 seconds, with light offshore ENE wind at 6 mph, energy at 1536, but again it’s only marginal. The very last entry on the 18th of August afternoon has a clean 4ft swell from the E, 8 seconds, with light cross-offshore wind from the S, but the energy is weak at 336.

So, if you’re not a big-wave specialist, the first week is a washout, and the second week is mostly flat with poor conditions. The standout is definitely the Wednesday to Friday of the first week for the heavy hitters, but be ready for size and a long paddle.

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.
