The Lowdown
Alright, let’s get into it. The next couple weeks are a bit of a rollercoaster, to be honest. We’ve got a solid opening act, but then things flatline for a while, and we’re looking at a long stretch of weak, small surf before things might fire up again at the very end. Here’s the deal.
Your best bet in the near term is Monday, August 10th. Hakashita (Big Island) is the spot. We’ve got a clean 5ft of east swell rolling in, with a period around 13 seconds. That’s some solid groundswell, and the combined energy is reading 1032, which is significant. The wind’s dead glassy in the morning, so it’s going to be super clean. This is a reef break, so that long-period swell is going to wrap in nicely. It’s rated for intermediates, and with conditions like that, it’s the standout of the first few days. The water temp is about average for this time of year, so nothing crazy there.
The morning is the time to be out. The afternoon gets a bit bumpy with a cross-on breeze, and the energy drops off. Still, that morning session is the one to chase.
Tuesday, August 11th, is still worth a paddle. The swell drops a touch to 4ft, but the period is still a solid 12 seconds, and again, the morning is glassy. The energy is reading 613, which is still moderate and should have some push to it. It’s not as strong as Monday, but it’ll be clean and fun. The afternoon turns onshore and quickly gets messy.
After that, we start to lose it. Wednesday and Thursday see the swell drop into the 4ft and then 2ft range. The energy readings fall off a cliff. It’s small, lacking power, and while the mornings stay glassy, the waves are just average. By the weekend, we’re looking at surf that’s around 3ft to 3ft. It’s surfable, but it’s not going to get your heart pumping. This stretch runs from the 13th through to the 22nd, and honestly, it’s a bit of a dry spell. There's a lot of small, weak, and often poor conditions with increasing onshore winds as the days wear on.
The one little blip in this quiet spell is Sunday, August 17th. The swell bumps back up to 3ft with an 11-second period, and the morning is glassy again. It’s a small window of clean surf, but it’s still small. The energy is only 275, so it’s not a powerhouse, but if you’re keen, it’s the best of a pretty average week.
Now, looking further out, towards the end of the period, things get interesting again. The models are hinting at a pulse of energy arriving around Monday, August 24th. The swell starts to build, and by the afternoon we’re seeing a jump to 5ft with a 14-second period. That’s a big shift. The combined energy reads 993, which is a strong pulse. The wind is a bit onshore, which isn’t ideal, but the size and period are there.
Then on Tuesday, August 25th, it looks even bigger. The swell pushes to 6ft from the southeast, with a 12-second period. The energy is reading 1044. This is a proper swell. But, and it’s a big but, this is a long-range call, so treat it with a bit of caution. The wind is looking cross-shore, which could make it a bit lumpy. At 6ft, this is getting into the territory where it’s more for the experienced crew. It could be a great day, but it’s not a guarantee this far out.
So, to sum it up: Monday the 10th is your best early call. The end of the month, around the 24th and 25th, has some serious potential, but it’s a “promising but not certain” kind of thing. In between, it’s pretty average. The water is about normal for this time of year, by the way. Keep it on your radar, but don’t get too pumped.

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.
