The Lowdown
G'day, I'm Rusty. Let’s have a look at what’s coming down the line for Halawa.
Right off the bat, it’s a bit of a quiet start. The first week or so is pretty much a write-off, with nothing surfable until the end of August. The wind is a constant problem – mostly cross-shore or cross-onshore breezes, nothing clean. The swell is small and weak, with the combined energy staying under 203 (moderate at best) and the periods are short, around 6 to 7 seconds on the early stuff, which gives you no push.
We’ve got a real drought here until around Thursday, 31st August. That’s a solid 11-day gap with nothing worth paddling out for. Then the picture shifts. A bigger, longer-period groundswell shows up on the afternoon of Sunday, 30th August. The swell bumps up to 7ft from the ENE, with a very long 13-second period and the combined energy jumps to 1554 (strong wave energy). The problem is the wind is still cross-onshore and the surf conditions are poor.
But, Monday, 31st August afternoon shows a glimmer. The swell hits 8ft from the ENE, period holds at 13 seconds, and the energy is a whopping 2078 (very strong). The wind goes cross-shore. This is big, powerful swell – only for experienced surfers. It’s still a bit lumpy with the cross-chop, but the energy is real. Then into the first week of September, we see two days – Tuesday, 1st September and Wednesday, 2nd September – with solid 8ft to 8ft ENE swells, long periods between 10 and 12 seconds, and strong wave energy (1458 to 2317). The wind stays cross-shore, still not perfect, but it's the best we’ve got in this whole forecast. For Halawa, a reef/river break, that long-period groundswell can line up well, but the cross wind will keep it from being a true standout.
Honestly, there are no absolute standouts here. The closest we get to a session is Tuesday, 1st September and Wednesday, 2nd September, where the swell is solid, the energy is pumping, and the wind is at least manageable. If you’re an expert and hungry, those two days are your window. For everyone else, this is a two-week stretch where you’d be better off doing something else.
Rusty.

Information about the Halawa Surf forecast
The above surf forecast table for Halawa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Halawa can be found by selecting the local surf guide option on the grey menu. Our Halawa 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 (Halawa) 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 Halawa 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.
