The Lowdown
Alright folks, Rusty here. Let’s get stuck into what’s coming up for Hakashita over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. The first real window of anything worth paddling out for doesn’t show up until Saturday morning, August 15th. The week ahead is a bit of a mixed bag, with only a few clean windows, and a lot of cross-onshore or choppy conditions in between. The water temp is sitting at a pretty normal 83°, nothing unusual for this time of year.
The standout period is definitely the last few days of the month, from Monday the 24th through to Thursday the 27th. That’s where the real energy kicks in. The best of the best looks like Wednesday morning, August 26th. We’re looking at a solid 6ft groundswell from the ESE, with a very long period of 14 seconds. The energy is pumping hard (1232), and with glassy conditions, Hakashita is going to be absolutely firing. This is proper, powerful groundswell, so the reef will be working and the waves will have that deep, open face. That’s a serious, expert-level session with the crowd factor on the table too – it’ll be a popular peak.
Leading up to that, Monday morning the 24th gives a taste of things to come. A much smaller but clean 2ft swell from the SE, with a super long 16-second period. The energy is still moderate (312) and the glassy conditions make it a far more mellow option for intermediates. Then Tuesday morning the 25th, the swell jumps to 4ft from the ESE, with a 14-second period and strong energy (560), again glassy and clean. That’s a solid intermediate session.
Thursday the 27th is still good, with 4ft from the E at 12 seconds, and glassy conditions in the morning. Energy is moderate (435). The afternoon looks even cleaner with absolute zero wind.
After that, it drops off quickly. Friday the 28th and Saturday the 29th are smaller, cleaner but much weaker, and the energy fades to a trickle (98) by Saturday morning. That’s the end of the ride for this outlook.
So, bottom line: ignore the first week unless you’re desperate for a small, clean knee-high cruiser on the 15th or 16th in the morning. All eyes on that Wednesday the 26th for the big one. Patience.
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.
