The Lowdown
Alright, grab a coffee and listen up, ‘cause I’ve been eyeing the charts for Hakashita and it’s a bit of a mixed bag. This is a reef break, and it’s inconsistent, so you’ve gotta be patient. The water temp is sitting right around average for this time of year, so nothing wild there.
The first few days, from Thursday the 13th through to the 16th, are pretty ordinary. There’s some small swell around 2ft to 3ft, but the winds are often onshore or cross-shore, plus there’s a risk of thunderstorms. Not worth paddling out for. On Friday the 14th morning, there’s a window of glassy conditions, but the swell is only 2ft from the S with a 9-second period, so it’s barely surfable. The combined energy is weak (122), so don’t get your hopes up.
The real standout I’m looking at is Monday the 17th morning. The wind goes glassy, the swell bumps up to 4ft from the E with a 10-second period, and the combined energy is moderate (302). The conditions are clean and the break is exposed, so sets should swing in. That’s your best bet in the short term. Tuesday the 18th has some similar size, but the wind is cross-onshore, so it’s not as clean.
Then we hit a dry spell. From the 19th right through to the 24th, the surf is poor or marginal at best. The swell drops back under 3ft, and the winds are mostly cross or cross-onshore, sometimes onshore. It’s a real flat patch.
But hold onto your wetsuit, because things get interesting around the 25th. Tuesday the 25th morning brings a solid 8ft SE groundswell, with a very long 15-second period. The combined energy is extreme (3091), so this is a big, powerful swell. That’s only for experienced surfers – it’s going to be too big for beginners. The wind is light cross-shore, and this long-period swell will be lining up nicely on the reef, but it’s a bit of a caveat: long-period swells like this can break a bit fast and hollow on reefs, so you need to be on your game. The afternoon is still big at 8ft, but the wind swings cross-onshore, making it a bit less clean.
The following week, the 26th and 27th, look promising. Wednesday the 26th morning is glassy with 4ft ESE swell, period 11 seconds, and moderate energy (449). Then Thursday the 27th morning is the top pick for the second week: glassy conditions, 4ft S swell, but a 12-second period and strong combined energy (602). The waves will be clean and well-shaped, but the long period means better sets at this reef setup.
Overall, the best windows are Monday the 17th morning, and then keep an eye on the 25th for the big stuff, and the 27th for clean, strong waves. The rest of the time, you’re better off doing something else.

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.
