The Lowdown
Alright, let’s take a look at what’s brewing for the next couple of weeks around Hakashita. I gotta be straight with you – for a solid stretch there’s not much to get excited about. But if you’ve got patience, the back half of this forecast has some serious potential.
We start off on Monday, August 17th with small, weak surf. Morning glass at Hakashita, a reef break, with a tiny 2ft easterly swell and a period of 10 seconds. The water is sitting at 83°, pretty much average for this time of year. The combined swell energy is weak (183). It’s surfable, but very ordinary. The glassy wind is nice, but the afternoon turns onshore and messy with a 4ft easterly swell and poor conditions. Honestly, not worth paddling out for.
Tuesday the 18th through Sunday the 23rd is a real flat spell. We’re looking at tiny, weak swells between 2ft and 5ft, mostly from the east or south, with periods of 8 to 10 seconds. Winds are cross-onshore or onshore most of the time, and there’s a risk of thunderstorms or moderate rain pretty much every day. The combined energy stays well under 500 – that’s weak, weak stuff. No decent surf in this stretch. About six days of nothing to write home about.
Now, here’s where it gets interesting. On Monday, August 24th, things start to change. We get a pulse of longer-period swell, 5ft from the southeast with a 17-second period. That’s proper groundswell, and the combined energy jumps to 1392 – moderate. Winds are light and cross-shore, so it’s not a total loss, but the conditions are still a bit marginal. This is more of a warm-up.
But Tuesday, August 25th? That’s the standout. Morning glass at Hakashita – wind is dead calm, just a light air. Swell hits 12ft from the southeast with a 16-second period. The combined energy is massive (6628). This is big, powerful, long-period groundswell. That’s expert territory all the way – over 8ft, so it’s not for beginners. The reef setup here should handle that long period well, giving some proper shaped waves, though expect longer lulls between sets. The afternoon stays clean with light cross-shore winds, still 12ft. This is the peak of the run.
Wednesday, August 26th keeps the energy going. Morning is clear, with a 15ft swell from the south-southeast at 15 seconds. Combined energy is 8142 – strong. Winds are light and cross-shore. This is another day for experienced surfers only. The afternoon drops a bit to 13ft with a shorter period of 13 seconds and a light cross-onshore breeze, still powerful but less clean.
From Thursday the 27th through to the end of the forecast, we’ve got continuing swell, but the wind turns more moderate to breezy, mostly cross or cross-onshore from the east-northeast. Swell sizes stay in the 8ft to 20ft range, with periods varying from 10 to 12 seconds. That Saturday, August 29th afternoon, sees a massive 20ft south-southeast swell with a 12-second period and combined energy of 9072 – that’s very strong energy. The wind is a gentle cross-shore, so it’s not blown out, but it’s still big and powerful. Only for the brave.
Looking into the start of September, Monday the 31st of August afternoon has a 13ft easterly swell with a very long 17-second period, combined energy of 9770 – that’s a serious amount of water moving. Winds are light cross-onshore though, so it won’t be perfect. Tuesday, September 1st sees the swell dropping back.
So, the real winners here are Tuesday, August 25th and Wednesday, August 26th. Glassy or light cross-shore winds, big long-period groundswell from the southeast, and that reef at Hakashita is going to handle it well. Just be aware, with that size and power, it’s strictly for experts. Crowds are possible at this spot, so get in early.
This is Rusty, signing off.

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.
