The Lowdown
Alright, Rusty here. Let's break down this 16-day window for Halawa.
We've got a pretty rough start, I gotta be honest. The surf is on offer straight away from the 31st of August, but it's basically a write-off for a solid stretch. The swell is there, around 7ft from the ENE, with moderate wave energy (462), but it's marred by strong cross-shore winds. This makes for lumpy, choppy, poor conditions. That pattern holds for the first four days into early September. There's a real gap of about a week where the conditions are too ugly to recommend a paddle.
Come the 5th of September, the swell jumps in size to 8ft from the ENE, with a big jump in energy (2453) and a decent 13-second period, but the cross-shore wind is still howling. It's called marginal, not worth a session. Then on the 7th of September, we see the biggest swell of the whole run. We’re talking a 13ft swell on Monday afternoon from the ENE, with massive energy (4988) and a 12-second period. But the onshore wind is terrible from the NNE, and there's a risk of thunderstorms. The setup looks more interesting for kite surfing than paddle surfing at that point, honestly. After that, the swell drops right off to nothing for a few days with offshore wind on the 8th, but it's tiny.
The true standout, the only window that looks genuinely firing, is the second weekend. On the 13th of September, the stars finally align. We’ve got a clean 7ft swell from the ENE with very good wave energy (643). By the morning it's clean with a light cross-offshore breeze, and by the afternoon it goes glassy. That is the session to aim for. The 14th and 15th of September still have good chest-to-head high swell from the ENE, but the wind is lighter and more onshore, so it won't be quite as perfect as the 13th. The water temperature is 27°, which is about average for this time of year.

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.
