The Lowdown

G’day, Rusty here, lookin’ at the surf for the next couple of weeks around Osaki Point. Honestly, it’s a real mixed bag. We’ve got a solid pulse of swell comin’ through, but there’s a big gap of quiet, blown-out days bookending it. The real story is gonna be from late Sunday morning into early next week, and then a few more days after that for the crew who can handle some size.

Right now, it’s flat. Saturday morning’s got tiny 1ft swell with a short 10-second period, and the water is a touch warmer than normal at 85°. No go. That clears up fast though.

Sunday the 2nd is where it starts to get interesting. First thing in the morning we’ve got glassy conditions with a light 2ft groundswell out of the east-southeast with a long 18-second period. Combined wave energy is moderate at 383. It’s small, clean, and the sets will have some nice shape. By Sunday afternoon it’s really on: 4ft from the east-southeast, 16-second period, and glassy winds again. The energy jumps to a strong 702. That’s the best window for a fun, user-friendly session. The long period means it might be a bit straight at the beach but if you pick your take-off spot it’ll be worth it.

Monday the 3rd sees the swell kick proper, but the wind turns onshore. Morning has 5ft east-southeast groundswell (16 seconds) but it’s blown out by easterlies at 9 mph. The energy is hefty at 1445, but the quality drops fast. By Tuesday the 4th, the swell is 8ft and rising, with the same cross-onshore chop. This is gettin’ big for a beginner, and the conditions are messy. Tuesday afternoon the swell hits 12ft with a 17-second period – energy is a massive 13197. That is solid, heavy water and only for experienced surfers. The wind is still onshore, so even though the power is there, it won’t be pretty.

Wednesday the 5th is the standout for serious power. Morning has a 16ft east-southeast swell (17 seconds) with clean offshore winds. The energy is monstrous at 14351. It’s the biggest, cleanest swell of the run, but it’s way too big for Osaki. Wednesday afternoon it’s 18ft, still offshore. If you’re an expert, this is a window, but the forecast notes the swell is predicted to be too big for this break.

Thursday the 6th keeps the big stuff comin’: 23ft swell with 18-second period in the morning, offshore winds, and a staggering 33369 energy reading. Again, this is only for the brave or the foolhardy, and the break might just close out. Friday the 7th has 21ft swell, still big, but the wind is howlin’ at 22-25 mph from the east-northeast. Conditions get ugly after Thursday.

From Saturday the 8th onward, it’s a write-off. The swell drops from 15ft but the wind stays rippin’ at 25 mph straight onshore. We see rain and thunderstorms, and the energy fades from 11436 down to under 200 by the end of the second week. The message from Sunday the 9th all the way through to Sunday the 16th is the same: poor surf conditions. There’s a big gap of about a week and a half with no recommendations. For a break that is normally consistent, this is a proper lull. It won’t stay this flat and choppy forever, but for now, the only interesting setups are for kite surfers with those strong onshore winds and solid, messy swell.

So, to sum it up: your best bet is Sunday the 2nd for clean, smaller waves. If you’re an expert and you’ve got the balls, Wednesday the 5th morning has the biggest, cleanest offshore swell of the lot – but it’s a beast.

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.
