The Lowdown
Alright folks, Rusty here. Let's get stuck into what's on the menu for Hakashita. This is a reef break that doesn't fire all that often, and the forecast shows a big gap of flat or poor conditions before we get the good stuff rolling in.
The first few days are a write-off. From Friday the 21st through to Sunday the 23rd of August, there's just no surf to speak of. The swell is tiny and the wind is all wrong. You’re better off doing something else.
Things start to get a little more interesting from Monday the 24th. We get a pulse of SE swell pushing to 4ft on Monday morning, with a period of 19 seconds – that's a proper long-period groundswell. The water temp is a balmy 84°, which is about average for this time of year. The energy is starting to build (1136), but the wind is cross-shore, not ideal. By Monday afternoon, the swell is up to 8ft, and the energy is strong (3282), but the wind is cross-onshore, so it won't be pretty.
Now, the real standout is Tuesday the 25th of August. This is the one to circle on the calendar. We've got a solid SE swell running, with a morning height of 15ft and an afternoon peak of 16ft. That's big, powerful stuff, and the period is a very long 16 seconds. The energy is massive (10172 and 11996). This is a serious groundswell, and being a reef break, it should handle that long period well. The wind is cross-shore, which isn't clean, but for that size, you'll take it. This is for experts only, no question. It’s a short window, but if you’ve got the skills, that Tuesday morning is the best chance for a proper session.
The rest of the week into early September is a mixed bag of dropping swell, poor winds, and messy conditions. The swell stays big on Wednesday the 26th, but with a strong onshore wind, it's a total mess. Thursday and Friday are still pumping but the wind is cross-onshore, keeping the quality down.
We get a brief reprieve on Saturday the 29th and Sunday the 30th of August. The swell drops right back to 3ft to 4ft, but the wind turns glassy or cross-offshore, giving us clean conditions. The period is short, so it won't have much punch, but it'll be a fun little wave for a longboard or a foamie. The energy is weak (289-349), so it's a mellow, clean day out.
Looking further ahead, the first week of September has a few more hopeful signs. The morning of Thursday the 3rd of September has clean, cross-offshore winds with a 6ft ESE swell, and the energy is moderate (660). The Friday the 4th of September morning is a real highlight in the second week: an 8ft E swell with a long 16-second period, and clean cross-offshore winds. The energy is strong (3573). It's a promising setup, but it's a long way out, so keep an eye on it.
Overall, the standout is undeniably Tuesday the 25th of August. If you're a seasoned charger, that's your window. For the rest of us, the clean, small days on the 29th and 30th offer a nice, relaxed session.
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.
