The Lowdown
Alright, this is Rusty. Look, I’ve got to be straight with you—the next week and a half around here is a bit of a dud. We’re looking at a long stretch of weak, wind-affected surf that’s just not worth paddling out for. Don’t even bother looking at the water until the very end of August. Things go quiet, then they go big.
Starting on Wednesday the 19th of August, Hakashita is running tiny. We’re talking 3 ft of east swell with a short, weak period of 8 seconds. That combined wave energy is a measly 123 (weak), and with cross-shore winds, it’s nothing but wind ripples. The water temp is about average for this time of year.
Thursday the 20th and Friday the 21st are more of the same—small scraps of energy. On Friday morning there’s a brief window with glassy conditions and 3 ft south swell, but the energy is still only 195 (weak) and the quality is described as "very ordinary." It’s a tease, not a session.
From Saturday the 22nd all the way through to Monday the 25th, it’s just mush. Swells stay under 3 ft, periods are short, and the wind is cross or cross-on. The combined energy drops into the double or low triple digits. Save your wax.
Now, things start to get interesting around Wednesday the 26th of August. We’ve got a big pulse of 8 ft swell from the southeast at 13 seconds on Wednesday morning. The energy jumps to 1955 (strong), but the wind is a howling 35 km/h cross-offshore. It’s clean, but that’s a lot of juice for a reef break that’s inconsistent. This is big, raw, and not for the timid. Thursday the 27th gets even bigger with 12 ft faces, but the wind swings onshore and cranks to 50 km/h. That’s a washing machine.
The standout window, the one you’re waiting for, starts on Sunday the 30th of August. Sunday afternoon, Hakashita sees a 12 ft swell from the east at 13 seconds. The combined energy is a massive 8318 (very strong). The wind is light and cross-shore. Conditions are "marginal" in the data, but that’s a lot of water moving for a reef.
Then Monday the 31st of August morning is the real gem. We get 10 ft of east swell, a 11-second period, and perfect light offshore wind from the northwest. This is "exceptional surf conditions for expert surfers." The energy is 5958 (very strong). The swell direction matches the optimum southeast swell direction for this break. This spot is inconsistent, so when it lines up like this, you get on it.
Tuesday the 1st of September keeps the quality high. It’s glassy in the morning with 10 ft of south-southeast swell at a long 14 seconds. A long period like that is best on this reef setup, and the energy is 5694 (very strong). It’s clean and powerful.
But the absolute best on offer is Wednesday the 2nd of September. Wednesday morning is glassy, with a massive 18 ft swell from the east-southeast at 12 seconds. The energy hits 11767 (very strong). That is for experts only. It’s too big for anyone else. The afternoon gets even bigger at 20 ft, but the wind turns cross-on. The real session is that glassy morning.
Thursday the 3rd of September cleans up again with 18 ft east swell at 13 seconds and light cross-offshore winds. Energy is 11372 (very strong). It’s another expert day.
So here’s the call: forget the first week. The best is the stretch from Sunday the 30th of August through Wednesday the 2nd of September. The absolute standout is Wednesday the 2nd of September morning at Hakashita for the big, clean, groundswell. You’ll need to be an expert, but it’ll be worth it. Crowds are possible at this spot, so get there early.
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.

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.
