The Lowdown
Alright folks, Rusty here. I’ve been staring at the charts for Hakashita and I’ve got the story for the next couple of weeks. It’s a tale of two halves: a slow start that’ll test your patience, but then a wild, powerful finish that could be absolutely pumping.
We’re looking at Hakashita, a reef setup that’s got a reputation for being a bit fussy—it’s inconsistent, so it doesn’t always fire. That’s important to know. Right now, we’re in a bit of a flat spell. The waiting game begins because the first real action doesn’t kick off until Monday, the 17th, and even then it’s not much to write home about. You’ll see some small 2ft waves from the east, but with a short period of 10 seconds and generally onshore or cross-onshore winds, the conditions will be pretty ordinary. The combined energy is weak, only sitting around 185. We’re talking about a few days of this—through Tuesday the 18th and Wednesday the 19th—where the surf stays small and messy. It’s not worth paddling out for unless you’re desperate for afloat.
Then things start to shift on Thursday the 20th. The morning brings a small 3ft SSE swell with a clean, glassy surface and light NNE winds. The energy jumps up to a moderate 269, and for the first time, the conditions are “good.” It’s not huge, but the quality is there on that morning session.
Friday the 21st and Saturday the 22nd see the swell picking up a bit—hovering around 4ft to 5ft from the south—but the wind gets messy with cross-onshore breezes and the threat of storms, so the quality drops off. The combined energy gets into the moderate range, around 267 to 519, but the chop makes it a tough paddle.
Now, hang onto your board, because that long period groundswell starts building from Sunday the 24th. Monday the 24th starts with a clean 2ft SE swell with a period of 16 seconds. The energy’s moderate at 396, and it gets even better into the afternoon: 5ft SE, still glassy, and the energy jumps to 944. That’s the first real taste of what’s coming.
The standout weeks hits us from Tuesday the 25th of August through the end of the month. This is where it gets serious. On Tuesday the 25th, we’ve got a 7ft SE swell, glassy conditions, and the combined energy is strong at 2347. The swell ticks up to 8ft in the afternoon. This is excellent surf, but it’s getting big. At over 5ft, it’s starting to be a bit much for beginners.
Wednesday the 26th hits 8ft SE, still with a long 16-second period, and the energy is a very strong 3657. The morning has a clean, cross-off breeze. By this point, the swell is over 8ft, so you need to be an experienced surfer to handle it.
But the true highlight? Lock in Thursday the 27th of August and Saturday the 29th. Thursday morning delivers a 12ft SE swell with a massive 17-second period, clean cross-off winds, and an exceptional combined energy of 7660. That is a big, powerful ocean. The swell direction (SE) matches the optimum for Hakashita, which is a major plus. This is expert-only territory. The waves will be long, powerful lines, but that reef will be handling that energy like a champ. Expect long lulls between those big sets, making the paddle out doable if you’re fit.
Saturday the 29th is the absolute king of the run. We’re looking at a 15ft SE swell, glassy and clean in the morning, with a combined energy of 9111. The period dips slightly to 14 seconds, but the power is undeniable. The conditions are described as “exceptional for expert surfers.” This is not a day for the faint-hearted. It’s a big, raw ocean.
The swell starts to ease into the first few days of September, but we’re still dealing with a 12ft to 13ft swell through Sunday the 30th and Monday the 31st, with clean windows on the mornings. Just be aware that by Monday the 31st and Tuesday the 1st of September, the swell direction shifts around to the ESE and E, which might not be quite as perfect for the spot.
Overall, the first week is a write-off until Thursday the 20th, and even then it’s small. The real magic is the window from Tuesday the 25th through to Sunday the 30th. The standouts are Thursday the 27th and Saturday the 29th. If you’re an experienced surfer, you’ll want to be in the water early those mornings for the glassy conditions and massive, long-period groundswell. Beginners should stay well clear.
Rusty.

Information about the Hakashita Surf forecast
The above surf forecast table for Hakashita provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hakashita can be found by selecting the local surf guide option on the grey menu. Our Hakashita 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 (Hakashita) 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 Hakashita 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.
