The Lowdown
Right, grab a coffee, let’s have a look at what’s on offer for Halawa.
This is a tough one to call. The whole 16-day window is basically a long, flat spell with a few brief pulses of energy that get completely blown out by the wind. For the first eight days, from Tuesday the 11th through to the 19th of August, the surf is pretty much unsurfable. The wind is hammering from the east and east-northeast, mostly cross to cross-onshore, and the wave heights are either tiny or, when we do get a bump, the wind is howling. The strongest pulse comes in around the 15th and 16th, with swell heights up to 8ft, but the wind is a strong breeze and then a severe gale on that Sunday afternoon, making it a total mess. The combined energy gets up to 2525 on the Sunday morning, which is powerful, but it’s completely wasted with that wind. The water temperature is 80°, which is a touch above average for the time of year, so at least you won’t need a thick suit.
The only real standout, and I mean the only one worth talking about, is Monday the 17th of August. Monday morning sees a window of hope. The swell is from the NE at 12ft, with a period of 11 seconds, and the combined energy hits 3041. That’s a lot of punch. The wind swings to a cross-offshore from the ESE at 19 mph, and the forecast calls for clean conditions. That’s your best shot. The break is a reef/river setup, which is perfect for a long-period groundswell like this. It’s a fairly consistent spot, but it can get crowded sometimes, so get in early. The size is into the expert-only range, over 8ft, so this is not a day for beginners. The optimum swell direction is from the NNW, and this is coming from the NE, so it’s not perfect, but the clean conditions and the power make it the clear winner. The afternoon on the 17th gets lumpy again, so the morning is the window.
After that, the swell drops off hard and fast. From the 18th onwards, it’s back to tiny, weak waves with poor conditions. The energy drops to 41 by the 19th, and then we get a ghostly pulse from the west on the 20th with a 1ft, 11-second swell, but it’s not enough to do anything. The rest of the month is flat and crossed out.
So, the short story: if you’re an expert with a flexible schedule, the morning of Monday the 17th is your only chance for a real session. The rest of the 16 days is a write-off for surfing. This is a pretty normal blank run for this area when the trade winds lock in.

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.
